Question:

Electric motor power is not fixed?

Is the motor power of the electric car fixed? Or the power of the motor changes with the voltage, my electric car is 48V 450W 22a, I want to change the controller to 60V 800W, can I?

Answer:

The controller size is its control capability. The electric car is the 48V 450W, and the mere replacement of the controller ("60V 800W") does not change the overall performance of the electric vehicle

The output power of electric motor can be seen as the change of voltage (current).
