QS Motor 13inch 2000W - 8000W 273 brushless DC electric bike motorcycle hub motor
For 13inch E-scooter Wheel hub motor, it could be used for electric scooter, electric motorcycle.
273 motor means the diameter of iron ring of rotor is 273mm, for all 273 motor, e.g. 13inch,14inch,16inch & 17inch 273 hub motor etc., the configuration & performance is the same as 10inch 205 Hub Motor.
There is only one width of the wheel, 13X3.5inch, which could match with 130/60-13 Moped Tire.
There are many options for the power, from 2000W-8000W.
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
