While I check the specs and thought the driver could handle it, after about an hour of discontinuous use, the driver stopped working...
I used the following : Motor Specs: 24V 250w, rated current 13.4 Amps, No load current <2.2 Amps, Gear reduction 9.78:1
With this driver Dual channel, 5-25 volts 10 amp max continuous in each channel 30 amp max (upto 10 seconds)
While I ran the setup at no load, I checked the temperature of voltage regulator ic 7812 (on the driver board) after 45 mins or so, it was piping hot and the board had stopped conducting.
Also, the operation involved a pwm input from a potentiometer, which would gradually change the speed of motor from 0-300 rpm and had an emergency stop which would immediately turn the pwm to 0.
The motor would start slightly humming even at 0 pwm and would stop with a jerk when used emergency stop.
