July 21, will service the Shenzhen Metro Line 5 of the urban rail train, in the CSR Zhuzhou Electric Locomotive Co., Ltd. (hereinafter referred to as “CSR bike motor“) success off the assembly line. According to technical personnel, the Shenzhen subway train is the first time the use of domestic market traction electric bike motor, equipped with a CSR Zhuzhou bike hub motor Co., Ltd. successfully developed independently of the traction bike hub motor products. Reportedly, the bike hub motor than similar foreign products, cost 20% less cost.

Construction cost of about 80 percent of foreign imports

CSR bike hub motor propaganda minister Zhu Jianfei told reporters the South, according to a long, high-strength technology validation test, the company’s traction electric bicycle hub motor of the technical indicators and very similar products imported, the cost is equivalent to the latter 80% follow-up maintenance costs only about 50% of the latter.

As a subway train the “heart”, traction bike hub motor is the core technology elements of the train, the train is pushing the cost of acquisition and maintenance of key components. According to the CSR bike hub motor to the source, every subway train by a total of 16 installed traction bike hub motor calculations, the cost of similar imported products equivalent to 80% of the standard means cost savings for each train at least 30 million, saving maintenance cost of $ 1.6 million. The Shenzhen Metro Line 5 quantities of eight trains, the subway operator side in one fell swoop to save the purchase and maintenance cost of more than 15 million yuan.

“China-made new subway excellent traction bike hub motor design, the technical indicators have reached international level of similar products, and by virtue of small size, light weight, excellent insulation properties, etc., more cost-effective than the international product.” CSR bike hub motor Publicity Minister Zhu Jianfei told reporters.

It is understood that the Shenzhen line 5 using Y Q-190-5-type asynchronous traction bike hub motor developed in November last year. “Our bike hub motor to meet the environmental climatic conditions in Shenzhen and lines, power supply and gauge conditions, reached the world advanced technology level.” Zhu Jianfei said. In addition to the quality of clearance, CSR bike hub motor with similar products, compared with a clear price advantage, is expected to slightly better in terms of competition.

Break the international monopoly of imported brands

Since 1984, successfully developed China’s first YQD -300 electric locomotive with AC traction bike hub motor has CSR bike hub motor in the year to promote technological breakthroughs in recent years, metro bike hub motor to speed up the localization process. And Shenzhen Metro Line 5 electric bicycle hub motor of similar products YQ -190-3 type bike hub motor landing in Beijing in December last year Fangshan Line subway. This year, the CSR Zhuzhou bike hub motor to provide traction electric bicycle hub motor project as well as Shanghai Metro Line 1, Shenyang Metro Line 2, Chongqing and Guangzhou Subway Line 6, 1,2,8 subway line.

“This year also includes the first major breakthrough into the European market, Izmir, Turkey to sign the light rail project, and volume manufacturing to 16, which is representative of the South China car bike hub motor bike hub motor subway traction vehicle with the European debut . “CSR bike hub motor to the reporter concerned. In addition, exports of CSR electric bicycle hub motor vehicles to maintain Singapore’s subway project supporting the development of electric bicycle hub motor, has achieved mass production, breaking the foreign giants for high-end metro and light rail traction system monopoly.

According to reports, South car sales this year expected to reach last year’s 2.5 times. And gradually replaced by a single manufacturer to create a combination of physical transformation and investment.

bike conversion kit for transport

Posted by on January 2, 2026 Comments Off on bike conversion kit for transport

bike conversion kit is the most common means of transport, is now able to buy everywhere, but the style and beautiful and light, as long as you want to buy, Na Zhaoqian to which the supermarket can be easily bought ride. In today’s traffic congestion is very severe cases, the cycling trip is a wise choice.

In the Great Northern Wilderness, I will not ride, even if someone took my car I can not go up (now still can not go it ^_^)。 After returning to the city, I Baijiazhuang Plant that is near the bulb before the bulb factory work, Chaoyang District. At that time I lived in the South of simple body work building, not far from the factory. We are morning and evening classes to work two shifts, early morning before 6:00 to duty, night shift will have 10 points to go home.
In order to rely on more than a moment when the early shift bed, I began to learn to drive a three-day course.

I heard my neighbors brother ride to school, take the initiative to lend me an old woman car, and enthusiastic and became my coach. Tightly clutching his back after the hanger, so I get to ride forward, rest assured, at first I did not dare look to the future, he kept looked at the ground, so the car will be a time to the side of the dump, thanks to a neighbor Big Brother’s escort, I almost can not Shuaiguo wrestle the riding of forward. Three days later, my riding skills have come a long way to grow, I can separate the two wheels along the road that circle around the riding too fast. Excited I was almost to the world declaring: I will eventually ride it! (Not included here pulley ah ^ _ ^)

Learned to ride, but the car where? The planned economy era, what to buy tickets should, bike conversion kit votes, sewing machine vote counting in a variety of furniture are the most scarce of the time. We factory pumping a few tickets every year, is the drawing of lots in accordance with the workshop team decision. The first time I hand a little bit smelly, nothing to catch. Finally caught a second bike conversion kit votes, so happy I can not wait to go home to my mother with me to buy a car. I remember when the Kanto shop near a bike conversion kit shop, I just bought a life where the first one bike conversion kit, the Flying Pigeon female car, 26’s, dark green color is very pretty, I I liked it, remember it took like 154 dollars. So the next day I started cycling to work, and daily round-trip time was reduced by nearly an hour it ^ _ ^.

Perhaps it is getting too much, I am pleased the less than six months, one day, a colleague to take my car to work, the results of a semi-tractor on the road and collided into my car and knocked out of shape, both wheels are almost twisted into a twist, but fortunately she were not injured. She had said he would pay me a new car, but she later changed his mind and refused to pay my car, I only agreed to repair. But my brother is that neighbors bike conversion kit Repair shop, shaking his head after he saw the car that did not fix it, even if the repair was able to ride away and will also affect the quality of life of the car. So I had to find that my colleagues once again express my meaning, I have a new car requires compensation, but also betray her, and insisted on the tube not pay car repair. She’s not unreasonable annoy me, I found the workshop director to complain, and the director is a very reasonable man, he and the secretary of the workshop repeatedly to do the work that my colleagues, she promised to pay me a new car.

So my first one bike conversion kit to come to an end with this result. Succeed it is a black, Flying Pigeon, 26 female car, the car has been accompanied me to the end of 2003, big day in front of my house was stolen by a thief. Now I travel all take the bus into the subway, every block on the road, I will miss the companionship I did get the bike conversion kit to …

he survey of electric bike conversion kit

Posted by on January 2, 2026 Comments Off on he survey of electric bike conversion kit

According to the survey of electric bike conversion kit has become the sale’s biggest problem, and serious problems to consumers, the convenience of electric bicycles as a result of the problem because the battery is not convenient, then the convenience of electric bikes on the greatly reduced, then consumers in the purchase of electric bicycles The process should be noted that the battery problem?

Primarily concerned with the battery capacity and voltage indicators. Electric vehicle battery is the main power source, the battery voltage and capacity is a combination of different combinations, electricity capacity, power, driving range so that the difference in the price are 2 to 3 times. So in the time of purchase, to find out the buy bike conversion kit in the end is how many volts, how many amps. Under normal circumstances, bike conversion kit 48-volt 20-amp 36 volt 10 amp than the fully charged one-time driving distance is longer, in general, the battery capacity, the greater the power, the price corresponding to high.

Second, we must ask electric vehicle warranty warranty period and specific content. Businesses are generally committed battery warranty for one year, but businesses said Paul, “year” is divided into periods of dollars: generally refers to the date of purchase, quality problems within six months of battery replacement, replacement of six months to a year maintenance of the old battery, continued to use the issue to a year after the business is not responsible.

Therefore, consumers in the purchase of electric vehicles and businesses time to negotiate a good battery specific warranty periods and the corresponding content, and indicated on the warranty card to avoid consumer disputes.

Finally, select the brand, service and reputation. Brand, service and word of mouth publicity is the best way to electric cars. Consumers buy not only to choose good quality car battery, but also than the service than the brand, pay attention to whether the product has a service point in the region, in the quality of service, reputation in the word of mouth how to fail the future of electric cars When, in the shortest possible time to be resolved.

Whether it is the battery or are in the purchase of electric bicycles should be noted, carefully follow the principle, and companies that focus on quality, focusing on after-sales service, so that electric bicycles can be a real blessing consumers!

How to Select bldc motor and stepper motor

Posted by on January 1, 2026 Comments Off on How to Select bldc motor and stepper motor

How to Select bldc motor and stepper motor?

Mainly depending on the specific application of the case may be, simply to determine: the nature of the load (such as horizontal or vertical load, etc.), torque, inertia, speed, accuracy, acceleration and deceleration, etc., the upper control requirements (such as port interface and communication requirements), is the main control position, torque or speed mode. Power supply is DC or AC power or battery power supply, voltage range. Accordingly, to determine the motor and equipped with the drive or controller models.

Choose the stepper motor or bldc motor controller?

In fact, the choice of what kind of motor should be based on the specific application, depending on their own characteristics. Please see table below, naturally understand.

Stepper motor system bldc motor system

Small and medium-range torque torque (20Nm usually less) small medium large, full range

Low speed range (usually in the following 2000RPM, high torque motor is less than 1000RPM) high (up to 5000RPM), DC bldc motor can even reach 1 to 2 million r / min

Main control position control diverse intelligent control, position / speed / torque mode

Vibration at low speed smoothness (but with a sub-type of drive can be improved) is good, runs smooth

Accuracy is generally low, higher high when the sub-type drive (depends on the specific feedback device resolution)

Torque-frequency characteristics of high speed, good torque down fast torque characteristics, features hard

Overload overload feature will be out of step 3 to 10 times overload (short)

The majority of open-loop feedback control mode, the encoder can also be connected to prevent the loss of step closed loop encoder feedback

Encoder Type – Optical Rotary Encoder (Incremental / Absolute), resolver-based

Response speed is generally fast

How equipped with bldc motor controller?

Posted by on January 1, 2026 Comments Off on How equipped with bldc motor controller?

How equipped with bldc motor controller?

According to the motor current, with the greater than or equal to the current drive. If you need a low vibration or high accuracy, can be equipped with a sub-type drive. For high torque motor, as with high voltage drive to get good high speed performance.

2 phase and 5 phase bldc motor What’s the difference, how to choose?

2-phase motor and low cost, but the larger the vibration at low speeds, the torque at high speed down quickly. 5-phase vibration motor is smaller, high-speed performance, compared with 2-phase motors, high-speed 30 to 50%, in some cases replace bldc motor.

When to select a DC servo system, servo it What’s the difference?

Bldc motor into a DC brush and brushless motors.

Brush motor, low cost, simple structure, starting torque, wide speed range, easy control, the need to maintain, but easy to maintain (for brushes), generate electromagnetic interference, the environment requirements. Therefore, it can be used for cost-sensitive general industrial and civil applications.

Brushless motor, small size, light weight, large output, fast response, high-speed, inertia is small, smooth rotation, torque and stability. Control complex, easy to implement intelligent, flexible way to their electronic commutation, the commutation can be square wave or sine wave commutation. Motor maintenance-free, high efficiency, low operating temperature, electromagnetic radiation is very small, long-life, can be used in various environments.

AC bldc motor is brushless motor, is divided into synchronous and asynchronous motors, motion control in general are currently with the synchronous motor, its power range, can do a lot of power. Large inertia, the maximum rotation speed is low, and with the power increases rapidly reduced. Therefore suitable for low speed applications running smoothly.

The motor should pay attention to the problem?

The power to run before you make the following checks:

1) the appropriateness of the supply voltage (overvoltage is likely to cause damage to the driver module); for the DC input of + / – polarity must not be wrong, the motor drive controller on the model or the current setting is appropriate (do not start too);

2) control signal line connected, secure, industrial site is best to consider shielding (such as the use of twisted-pair);

3) Do not put the need to take the start line all connected, only the most basic system even as, well, then gradually connection.

4) The grounding method must be clear, or the use of float is not connected.

5) began running half an hour to closely observe the motor state, such as the movement is normal, sound and temperature, and found the problem immediately stop adjustment.

leaf smart car race motor

leaf Super model car contest rules, no restrictions on the use of motors, as long as the right, players can choose the hub motor. Having an expert auto locksmith that you can call anytime is also a good
thing to have, though not necessary. If you are having a hard time finding an auto lock smith you can find an auto locksmith company in West Palm Beach FL here.So how to choose the right motor it? Oaks from little acorns, the motor is a fundamental part of the model car, the motor will have a direct decision model cars will eventually run fast? When you want to find out how much your car is worth can be a useful resource. With an office in San Diego they can help you get you paid quickly for your car. AC and DC motors are generally divided into two, thanks to battery-powered, combined with a model car of this level, it is generally used as the drive hub motor.It may be considered an exception to the brushless hub motor, and it is essentially a AC motor. The hub motor’s basic principle is nice and simple, there is no nonsense. Fixing a car can be difficult when you don’t have the right parts, but you can easily get new Bentley Parts from leaf Car Parts.

Specifically, the optional hub motor in the following categories: general motors, coreless motor, brushless motor.

1 General Electric. Is the most common, the most common motor.

2. Coreless hub motor. Coreless DC motors are permanent magnet, servo motor, the main difference with the ordinary use of the motor is coreless rotor, also called hollow cup-shaped rotor. Coreless motor compared with ordinary motor, has the following advantages:

a. higher energy conversion efficiency (a measure of its energy-saving features of indicators): The average efficiency of 70% or more, some products can reach more than 90% (normal 15-50% in the core motor);

b. Activate the brake quickly, fast response: mechanical time constant is less than 28 milliseconds, some products can reach 10 ms or less, the recommended area of ​​high speed running state, the speed control sensitivity;

c. reliable operation stability: adaptive ability, their speed fluctuations can be controlled in less than 2%;

d. less electromagnetic interference: the use of high-quality brushes, commutator structure, change the spark is small, can avoid the additional anti-jamming device; energy density: core motor with the same power compared to its weight, volume reduce 1/3-1/2; speed – voltage, speed – torque, torque – current standards such as the corresponding parameters presents a linear relationship.

Coreless motors are divided into brush and metal brush, brush carbon brush of high melting point than the metal resistance, strong overload capacity, peak current for frequent occasions (start / stop operation, forward and reverse operation, etc.)

3.brushless motor. Brushless motor stator windings made of three-phase symmetrical multi-star connection, with three-phase asynchronous motor is very similar. Stick with the motor rotor has magnetized permanent magnet, in order to detect the polarity of the motor rotor, the motor that has the position sensor. Drive from the power electronic devices and integrated circuits, etc., and its function is to: Accept the motor start, stop, brake signal to control the motor start, stop and braking; receiving position sensor signal and inversion signals used to control the reverse change the bridge off of the power tube to produce a continuous torque; accept the speed command and speed feedback signals used to control and adjust the speed; providing protection and display, and so on.

brushless motor and other motor comparison:

Advantages of brushless, brush motor on the brush to avoid damage to the defect, long service life. Fast speed, big power.

Disadvantages brushless machine load fluctuations may not respond, and this model contest for the motor load required to withstand very large fluctuations, the use of brushless motor may be (actually bound) appears the phenomenon of motor suddenly stopped. And brushless motor voltage range of smaller, less torque, control complexity, the current large to meet the requirements of the Japanese games do not brushless motor. So the basic rule out the brushless motor.

The above point of view, the most suitable for the game is hollow cup hub motor, had previously conducted experiments on the corresponding features coreless motor has a very profound impact. However, the coreless motor has its drawbacks, first of all is the price, coreless motors are more sophisticated motor, prices are generally very expensive, but also hundreds of cheap domestic one, expensive as MAXon, FAULHABER, thousands of one. With four-wheel drive, for example, the motor would take thousands, taking into account what the backup, put quite big ah. The other is the hub motor resistance than ordinary rough ah, improper use, then easily out mechanical failure, such as brush burn, the drive shaft off, I have broken several a night, a few thousand dollars gone ah.

Therefore, most of the teams, the more appropriate is the ordinary motor, the cheap, rough-resistant, pressure is good. Ordinary hub motor can be divided into several levels, the general classification by motor diameter, such as the RC130, RC260/RC280, RC380, RC540, and so on. Freescale is the RC380 motor racing competition organizing committee to provide Renesas level is RC260 motor. Generally the larger motor, the greater the power, the same level of motor parameters are also different.

If you pick it? Example. Suppose I want the rented car that can reach up to 4m / s speed, wheel diameter of 45mm, the transmission ratio 1:6, then the motor speed at least 10000r/min, taking into account the redundancy of the motor rated speed to achieve 14000r/min, only more but, even taking into account work by the overpressure, ie 6V motor in 10V (8 * 1.2) voltage, is higher than the motor rated speed 8000r/min, then you can visit royaldrive. Another important parameter is the power, experience, 1kg 3w about model car with the motor on it, of course, the power is the bigger the better.

Japan “MCR God” Haruo Shimazu car will use a committee of four to provide the motor (Mabuchi’s RC260-18130), as shown below, you can reach 3.8m / s average speed. And in 2009, Huazhong University of Science uses four RC-280 motor. Thus, an ordinary motor, as long as the design is reasonable, selection is correct, we can achieve good results. Select the motor, it is best to buy the regular manufacturers such as Johnson Electric, yushan motor, etc., generally corresponding specifications for reference, the quality is also reliable. After a long tiring day, your cars is just like you, it wants to have a best wash it deserves. You can bring in best pressure washers for your car to make it presentable and cool again.
