1. Comparing Wheel Hub Motor with Gear Differential Motor

1). Simplify to make a electric-car. Gearbox, transmission shaft, clutch are no need. Which save space.

2). It could be installed in wheels, and easy to be hybrid car.

3). Easily to make 4-wheel drive, which could spot turn.

4). Support regenerative braking

5). High efficiency: 85~92%

There are many options for the power, refer to below list.

PS. 1. Above quotation base on 13X3.5inch wheel.

2. For 273 motor, the voltage is 48V~144V.

3. Above configuration is suggested for mass production,

for EV enthusiast, V2 & V3 motor could be over-voltaged to gain more speed/performance (customizable).

4. There are more powerful , e.g. 8000W Dual Stator Hub Motor, equal to 16000W rated, which is hand-made, take approx 40-50 business days.

For the max continuous rating power, the data should be tested in lab, which means no further temp rise at the power (e.g. 100 degree inside of motor at the power). Unluckly, all the continuous power rating is not done yet.

Due to our understanding and feedback of customer, for 205 3000W V3 motor, the max continuous power could be 6000W, peak power 12kW (even 18kW). For EV enthusiastic, they could input more power to enjoy the high performance, but the motor might suffer from over heating or even burnt. For EV Manufacture, we should notice the potential performance of motor, and keep some allowance for the whole e-scooter kits. include motor, controller, battery. to get them as stable as possible & decress the repair rate (consider all the usage environment). E.g. 3000W as continuous rating power.

PS. Temp Sensor Options: KTY84/130, KTY83/122, [email protected] 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.

5. How to Find a Suitable Motor

To customized a suitable motor, could you pls. inform below points:

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

We could suggest most suitable motor accordingly, thank you for your cooperation.

PS. To calculate the speed, v(km/h)=n(r/min)*2rπ(m)*60/1000,n=load RPM, r=tire radius.

For speed less than 100KPH, consider the Windage Resistance & Rolling resistance.

the load RPM is appr 0.9 * no-load RPM. v(km/h)=0.9*n(r/min)*2rπ(m)*60/1000

For over 100KPH, V=0.85*RPM*2rπ*60/1000

After confirming the motor, we could try to offer suitable motor kits, e.g. Motor Controller, Wheel RIM charger, speedometer, throttle, brake, DC-DC converter, etc.

PS. So far, the battery is not avaiable.
