Promotional Various Durable Using QS Motor E-car 273 8000W 50H V2 Electric car brushless dc hub motor
|
For 273 E-Car wheel hub motor, it could be used for electric scooter, tricycle, light car.
273 motor means the diameter of iron ring/hoop is 273mm, for all 273 motor, e.g. 13inch,14inch,16inch,17inch 273 e-scooter hub motor,
273 spoke hub motor, 13inch,14inch,16inch.17inch 273 single shaft hub motor, 273 E-car Hub motor etc., the configuration & performance is the same as 13inch 273 Hub Motor.
For E-Car hub motor, we can also provide 205 type, you can refer to below hyperlink for the detailed:
1. Key Features
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%
2. QS Motor 273 3000-8000W E-car hub motor List
P.s.: 1. Above quotation base on 273 electric car wheel hub motor, 48V~144V.
2. Above configuration is suggested for mass production,
for EV enthusiast, V2 & V3 motor could be over-voltaged to gain more speed/performance (customizable).
3. Water Cooled Hub Motor, 12kW 70H,8kW Dual 50H Stator E-car Hub Motor could be customized (hand-made).
4. The default Disc is moped standard, PCD3*80mm, it could be PCD 4X114.3mm, M12. Extra 135.0/piece

4.Differences 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 /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.
