QS Motor 3000W - 16000W 273 brushless dc electric car engine single shaft wheel hub motor for sale sale
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.
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 car wheel rim, PCD Customizable CB ≥60mm
There are many options for the power, refer to below list.
PS.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). These super power hand-made motors are not for new customer, we suggest to test 273 50H V3 firstly if necessary.
4. The default Disc is moped standard, PCD3*80mm, it could be PCD 4X114.3mm, M12. Extra 135.0/piece
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, 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.

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
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.

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).
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%.
