LCD bldc motor controller for e-bike

There are two types of hub motor wheels are used for e-bikes. One type is hub bldc motor , the other is brushed hub motor. Because the brushed motor had some disadvantage of high noise, shorter-use life, low efficiency..

These days hub bldc motor wheels are used for electric bikes widely and had replaced brushed hub motor.

So more and more motor controller are showed in market. For example: cruise brushless controller , regen brushless controller, programmable brushless controller, lcd bldc motor controller…

Convert a bike to an e-bike, we should choose a hub bldc motor wheel with brushless controller and throttle, brake lever,on/off switches,disk brake,front&rear lights,horn..etc accessories

European like 250w hub bldc motor and North America prefer 750w / 1000w bldc motor. How to purchase a good brushless controller to drive this bldc motor .

Generally 250w bldc motor need to be driven by 6-MOSFET brushless controller, and a 9-MOSFET motor controller dirves a 750w bldc motor,a 12-MOSFET brushless controller dirves a 1000w bldc motor.

Now nearly all types of brushless controller for e-bikes have cruise, alert, reverse, limited speed..etc. function.

If you buy 1 set 48V DIY kit, you had better to choose 48V 12-MOSFET/15-MOSFET brushless controller. Please don’t order 9-MOSFET motor controller to drive your 1000W brushless controller, it’s the heart of e-bike. 1000W bldc motor will bring larger current and high temperature, 9-MOSFET can’t afford.

For the bulk .of motor controller, larger, better. Larger bulk has better cool system.

In past, there was a guy sold regen motor controller, but nearly all sold regen controllers were broken in 30 days. Because when you brake, this regen controller will bring twice current to stop your e-bike, thus larger current would break MOSFET directly.

Now programmable controller is still showed in market. This brushless controller seem has nice face, but its head is small, can’t stuff more MOSFET. Use this brushless controller to drive 750w / 1000w bike system and break this nice face controller is normal. Don’t be arrest by programmable. You will find nothing for actual use when you use.

We have LCD cruise controller, more MOSFET, don’t worry your motor controller will be broken.

16″ 36V 250W front electric hub motor kit

With the price of gasoline rise and pollution,a bicycle is good for an environmentalist.

Riding a bicycle is a great non-polluting way to get exercise and get around, but a steep hill or a long commute can turn into an unpleasantly sweaty affair. Converting a bicycle into an electric bicycle can create a vehicle with all the advantages of a regular bike, but with a little power assist to get past the disadvantages. You can assemble a set of components on your own or buy a matched electric bike conversion kit!

Compare to buy a new electric bicycle,order an electric bike kit to convert your existing common bicycle to be electric,less cost.

Leafmotor has one new type of e bike kit for old men and children.
It’s a 16″ front 36V 250w electric bike kit that includes:
1.16″ 36V 250W front casted brushless gearless hub motor is fit for 100mm front fork.
2.36V 250W 6-MOSFET brushless motor controller working with LCD,display speed,mileage,battery gauge..
3.Twist throttle or thumb throttle(default is twist throttle)
4.Brake lever
5.Three button ON/OFF switch is used to control front&rear lights,horn,cruise…

This hub motor is make up of aluminium hub,cover,magnet,rotor, winding,axis etc.The netweight is about 5.13kg,use 16×2 1/4″tyre.Motor speed,we can customise according as your actually need.

The difference between ordinary motor controller and bldc motor controller

The difference between ordinary motor controller and bldc motor controller

Generally refers to the bldc motor controller. Brush DC motor controller stator magnet (or excitation coil), the rotor of the coil. As the current need to enter the rotation of the coil and the coil rotated 180 degrees due to be exchanged once the direction of the current flowing through the coil, therefore, used for brush DC motor controller connected to the body coil and current. Reversing the direction of switching bodies with a commutator and brush composition.

bldc motor controller generally coils on the stator by the rotation axis of the magnet mounted on the output drive shaft work. To solve the current problem for the use of Hall devices measured magnet pole position, the control circuit to external change, to change the current direction.
bldc motor controller because there are no brushes, long life, motor controller structure has been simplified.
