QS 20inch 1000W 205 (40H) Single Shaft Normal/V1 Type Hub Motor     

When placing order, pls. advise below points:

1. E-tricycle or E-car, tire model?
2. Volt and wattage of motor, Speed, and torque/climb angle ? 
3. Your vehicle weight and loading weight? 
4. Lithium or lead-acid Battery?

Thank you for your cooperation.

²Speed Suggestion

The  voltage we could be 48v-96v, the max. speed can be customized to from 30-50km/h.

V=0.9*RPM*2πr*60/1000   V (KPH), RPM=un-load RPM, r=radius of tire

As Power=Torque*RPM/9.549, the more RPM is, the less torque it will be

Tips: Please advise Voltage & RPM when placing orderIf there is no marking, we will make it 48V 288RPM.

We suggest to choose Balance/2nd model for mass production, as the repair rate of high speed model will be higher.

 

²Controller Suggestion

The power of controller should ≥ power of motor.

For 20inch 205 1000W motor(rated speed 30-50km/h), you could choose 40-45A(limited current) controller. 

 

When you using overvoltage, then the max. speed increased sharply, the real power is not 1000w. The higher speed get for motor(overvoltage condition), the bigger limited current should choose for matched controller, when considering the starting acceleration capability and climbing performance.

If you dont how to match controller, please dont hesitate to contact with ue. We could also provide suitable controller.

²Motor Design of inner configuration

There are three types, Normal/V1 type (low cost), Export/V2 type (Cost-effective) and Extra/V3 type (Best Performance).

1. Comparison between V1 and 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. Comparison between V2 and 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/phase wire and thicker Cross-sectional area section,  bear more current in usage. Magentic Steel: V3 is wider and thicker.  Efficiency:  86~88%(V2) 88~92%(V3) Thus, V3 have best performance.
