Posted by on August 4, 2023 Comments Off on Leaf Ebike Kit Questions

Q: I would like to purchase a 27.5″ electric hub motor kit that fits in 135mm dropouts and I have a 72v (20s) battery capable of 80A continuous that I would like to use.  Several questions please:
A. Can I buy a 27.5″, Freewheel, Rear, Wide Rim, kit that fits in 135mm dropouts with the “2000W ~ 5000W programmable controller” instead of the controller that normally comes with the hub motor kit and if yes, what would the total price of the hub motor kit be before shipping cost are added?
B. What is the internal width of the widest 27.5″ rim you have available?
C. Can I get the 5mm phase wires with the motor configuration I specified in “A.” above?  If yes, how much would it change the price?  If no, what are the largest diameter phase wires I could get?
D. Do all Direct Drive Leaf motors now use the .035″ thick laminations?  I would definitely want them. 

A: A. 135mm dropout – max make 48v 1500w rear bike motor,see below drawing. no room to make 2000w motor. (This 48v 1500w motor with 3mm phase wire can work with 48v or 52v or max 60v)
https://www.leafbike.com/u_file/2301/01/photo/1500w-rear-bike-motor-drawing_53f4287594.jpg 

     But, if no freewheel, not pedal, can make it to be 48v 2000w front bike motor(see below drawing) that fit for 135mm dropout and can use “2000w~5000w programmable controller”
This 48v 2000w motor with 6mm phase wire can work with 48v or 52v or 60 or 72v batteries.

We have three kinds of 27.5 inch rim, one is 23mm width, the other two is 25mm and 32mm width.   (Max 32mm width)

If 26 inch, we have 25mm, 32mm, 80mm width rims.

B. Our 27.5 inch 32mm width rim, internal width is 25mm

C. 48v 2000w can use 5mm or 6mm phase wires.  (But 48v 1500w max use 3mm phase wires.

D.  All of our motors use .035″ thick laminations

Q:
Two more question regarding the “48v 1500w rear bike motor” phase wires:

Q: Cengalo is a Startup for a 4 wheeled lightweight car with 2 bike Hub motors on the rear wheels.
We plan a speed of approx 75 Km/h, downhill, with 20 inch wheels.
Can you offer the 48V 52V 1500W front spoke hub motor – electric bike motor with appox 800 rpm?
Motor type: brushless bike motor
Voltage: 48V / 52V
Power: 1500W
Max efficiency: 90.5%
RPM: 600
Mechanical brake: V
Cable location: shaft end, Left
Cable length:150cm / 60″
Install: spacing of 100mm fork
Noise: < 60 db Surface: Black painted Net weight: 6.9kg / 15.2 lbs Gross weight: 7.8 kg ( after packing ) A: 48V 52V 1500W front spoke hub motor - electric bike motor with appox 600 rpm. It's very fast. (Default the fastest) But also, we can make faster bike motor (over 700rpm) Q: The higher speed hub motor can be interesting for the vehicle. Than we can use 48V battery. We have yet to decide if the vehicle is 48 or 72 volts batteries. With the higher voltage (72V) battery, the same hub motor would have a 1.5 times higher speed. Do you have experience what is better for the car? A: This 1500w bike motor max use about 2.5mm phase wires. Can work with 72v battery. But uphill,if cable too hot,should stop at once. Q: Can you give a wholesale quote for the 1500W front spoke hub motor 100 psc / 500 pcs / 1000 pcs per order? We calculate the Cangalo Smartcar with this offer. Unfortunately we can't place an order until 28.2. We have to develop the vehicle, Cengalo Smartcar, first. You always answered quickly and hopefully will continue to do good prices in the future, so we can well imagine ourselves with Leafbike as a long-term supplier work.

What’s the difference between 36V 500W,36V 750W and 48V 1000W hub motors

Posted by on May 11, 2022 Comments Off on What’s the difference between 36V 500W,36V 750W and 48V 1000W hub motors

Q:What’s the difference between 36V 500W,36V 750W and 48V 1000W hub motors

A:36V 500W,36V 750W and 48V 1000W hub motors are all used for electric bikes,also called electric bike motors.They have the same figuration.These three motors are all made of the same hub,covers,
axis,bearings,hall sensor.So they look the same,but they have different magnet and rotor-winding.

36V 750W and 48V 1000W are the same hub motors,just work at different voltage,has different watts.

But for 36V 500W × 36V 750W（48V 1000W）
The difference between them is that gauge of the coil wires,turns number of the coils and height of magnet.

The height of 36V 500W hub motor’s magenet is 24mm,but 750W hub motor reach 30mm.Picture enclosed.

In market,36V 500W is easy to find it,but difficult to find real 36V 750W hub motors.

In China,36V 500W(48V 600W) motors are very popular and used for electric bikes,these motors seem to ours,but No.The height of our magnet is 6mm more than as usual,reach 750w or 1000w.North America like them,more like high speed motors,we can customize motor speed as customers’ actual need.

Now 26″ 36V 750W bike wheel reaches 20m/h and the speed of 48V 1000W is 27m/h.It’s standard speed.

Three-phase bike motor torque

Symmetrical three-phase winding leads to symmetrical three-phase currents produce a rotating magnetic field, magnetic field lines cutting the rotor winding, according to the principle of electromagnetic induction, the rotor winding produce e and i, the rotor winding in the magnetic field by the electromagnetic force, which produce the electromagnetic torque the rotor spin, the rotor output mechanical energy to drive the mechanical load spin.

In the AC motor, when the AC current through the rotor winding, the establishment of the armature magnet force, its electrical energy conversion and operating performance has a significant impact. So pass into the three-phase AC three-phase AC winding generate pulsating magnetic momentum, the magnetic momentum can be decomposed into two equal in magnitude, opposite the rotation speed of the magnetic momentum and to create in the gap and reverse Story magnetic field and. The two rotating magnetic field cutting the rotor conductors, and conductors were generated in the rotor EMF and induced current.

The current and the magnetic interaction of positive and negative torque. Forward torque is an attempt to make the rotor turn; attempt to reverse the rotor torque reversal. Superposition of the two torque motors turning up is to promote the synthesis of torque.
