Hi,
I have a 1kW 48V electric bike brushless motor and its controller. The throttle controls the speed of the motor, but I want to control the torque rather than the rpm.
Basically the motor should be set to certain speed, let's say 20rpm, and then controlling the torque (measured on the shaft) regardless the speed (i.e. 20Nm from 0 to 20 rpm)
I know that I need a current control loop, but I don't know how to do it.
Should I make it modifying the current speed controller or make it from scratch?
Is there anything off the shelf for this purpose?
Thank you
