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.


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.
