  1. Thanks for your comments. I thought that I could probably do it by measuring the current in the motor by one of the analogue inputs and then control the duty cycle. Reduce the duty cycle when the current is too high and vice versa. Like a closed loop.
  2. I have a Samba SM43-J-T20. I need to control a brushed DC-motor with 24 V/50 Watt with an optical encoder. I need a suitable motor driver with current sense for this. The task is to control the torque of the motor. I need a constant torque characteristic (Like if the motor would be supplied by a constant current source). This means that the motor delivers a defined torque regardless of the RPM. The RPM shall only be limited to an adjustable value. Can you make a recommendation for the motor driver and maybe a sample program for this job?
