3. QS Motor 12*5.0inch 1500W-5000W 260 Brushless DC Electric Dual shaft Detachable Hub Motor List
It's hub motor with wheel rim detachable.
There are many options for the power, refer to below list.
Note for 12inch 260 motors (electroplating wheel)
1.12x3.5inch 260 double shaft motor + USD38/piece = 12x5.0inch 260 double shaft motor
2.12x3.5inch 260 double shaft motor + USD52/piece = 12x5.0inch double shaft motor (only electroplating wheel)
QS Motor Specification (e.g. 5000W 260 45H V3)
Item: QS Motor 5000W 260 45H V3 Electrc Scooter Hub Motor
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.

4. How to find suitable hub motor
To customized a suitable motor, could you pls. inform below points:
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
5. Motor Drawing
For V3 Motor, the dropouts is 230mm.
For V1 Motor, the dropout could be 200mm.
Btw., it could also be single shaft (so far it's not detachable).
Refer to below picture.
