The controller is for an electric trials bike, so throttle response/ control is going to be everything. I want to try and emulate a petrol engine if possible, so have engine braking based on how far the throttle is closed. This will not need to be excessive at lower speeds, but can maybe be more violent at higher speeds.
I think I am going to try and implement this based on battery voltage, pwm duty cycle and motor speed. If I estimate the motor no load speed based on the battery voltage and pwm duty cycle I should be able to implement the right control for either light regen, or synchronous rectification (if below no load speed).

Can this damage the motor, or potentially produce an excessive amount of current from the generation? As you can see in the video I really didn't push it as I was worried it might damage the motor/ controller.
