Quanshun 20inch 500W - 1500W 205 Cast Wheel Bicycle Electric Motor
For 20X2.125 E-bike wheel, it could be used for e-bike, drift trike.
These are 205 hub motor, so the configuration & performance is the same as 10inch 205 Hub Motor.
Meanwhile, for 500W motor, it could also be single shaft.
Generally, the iron ring height is 35mm, it could be 27H 500W V1 hub motor.
For lastest 52mm iron ring, it could be 800W, 1000W, 1200W, 1500W hub motor.
It could be 800W 30H V1 & V2, 1000W 35H V1 & V2, 1000W 40H V1 & V2,
1200W 43H V1 & V2, 1500W 45H V1, 40H V3 (155mm dropouts).
For 20inch 205 cast wheel hub motor, we can provide from 500w-1500w, you can refer below link for the detailed information:
1. Key Features
1). Simplify to make a electric-bicycle. Gearbox, transmission shaft, clutch are no need. Which save space.
2). It could be installed in the rear to save more space for battery.
3). Support regenerative braking
4). High efficiency: max above 85%-92%
2. QS Motor 20inch Bicycle Cast Wheel Hub Motor
P.s.: 1. Above quotation base on 20X2.125inch wheel.
2. Above configuration is suggested for mass production,
for EV enthusiast, V2 & V3 motor could be over-voltaged to gain more speed (customizable).
3. Production Description
QS Motor Specification (e.g. 800W 205 30H V1)
P.s.: For less than 1000W motor, there is no temp sensor as default.
Temp Sensor Options: KTY84/130, KTY83/122, 10K@25C NTC(model MF58-103F3950).
QS Motor could work 120 ℃ in half an hour without damage.
Suggestion (Setting of Controller)
When it's 130 ℃ inside of motor (in 30s), the current should be limited 50%.
When it's 150 ℃, the controller shut down. When it drop down to 110℃, the controller work again.

Differences between V1, V2 and V3
1). Difference between V1 & V2
Holder: Iron(V1), Aluminum (V2)
Hall: One hall with Normal connector(V1), Two halls with Waterproof connector(V2)
Stator: V2 have a stronger configuration, more cooper, thicker section surface, energy saving in usage.
Magnetic Steel Grade: V2 ≥ V1
Efficiency: 84~87%(V1) 86~88%(V2)
In short, normal type is standard configuration, while export type is high configuration.The price differs because of the cost of raw materials.
2). Difference between V2 & V3
The raw materials are alike, main difference in inner construction.
For V3 (16 Pole Pairs): stronger configuration than V2, wider lamination, more cooper wire /thicker Cross-sectional area section, bear more current in usage.
Higher torque at same current, lower temperature rise, more stable in high current.
Magentic Steel: V3 is wider and thicker.
Efficiency: 86~88%(V2) 88~92%(V3); Thus, V3 have best performance.
PS. for the same V1 steel/iron stator motors, QS Motor performance better on lifetime & stability becasue of good raw material. So the cost is more than normal hub motor in the market.
Drawing
For 110mm dropout with bicycle disc brake, no freewheel, the maximum power is 1000W 205 35H V1 motor, which suit for electric drift tricycle.
