QS Motor 1000W - 3000W 205 brushless dc electric car singhle shaft wheel hub motor

 

For 205 E-Car wheel hub motor, it could be used for electric scooter, tricycle, mini/golf car.

205 motor means the diameter of iron ring of rotor is 205mm, for all 205 motor, e.g. 10inch & 12inch 205 e-scooter hub motor,

205 spoke hub motor, 10inch & 12inch 205 single shaft hub motor, 205 E-car Hub motor etc., the configuration & performance is the same as 10inch 205 Hub Motor.

 

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%

 

It\'s only hub motor without rim, it could be mounted in wheel rim, CB ≥60mm. PCD ≤ 110mm.

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

Product List

205 e-car price

PS. 1. Above quotation base on 205 electric car wheel hub motor.

      2. For 205 motor, the voltage is 48V~96V.

      3. Above configuration is suggested for mass production,

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

 

For the max continuous power rating

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 before.

 

Due to our understanding and feedback of customer,

for 205 3000W 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.

How to find suitable hub 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   

 

Electric Motor Kits

After confirming the motor, we could try to offer suitable motor kits, e.g. controllerwheel setchargerspeedometer,

throttlebrakeDC-DC converter, etc.

PS. So far, the battery is not avaiable.

 

QS Motor V1/V2/V3 Type Motor

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

QS Motor 1000W - 3000W 205 brushless dc electric car singhle shaft wheel hub motor

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.

E.g. 1. Choose C&U bearing which is motorcycle standard, more quiet when riding.

       2. High Coil space factor, better efficiency.

       3. Silicon steel sheet 0.35mm instead of 0.5mm, less current consumption & low temp rise.

       4. Insulation varnish outside of varnished wire, max 180 ℃ than normal 120 ℃. 

       5. Better magnet, demagnetizing less than 1% than normal 3%.
