Hi All,
I have a problem with the K2636 speed controller. I am using a brushed motor out of an old polisher. The problem is that the motor is surging the speed is low then it will go up for a short time and then slow again. When I switch it on the speed will first be fast and then slow. I adjusted the pot and speed controller but the problem remains.
Any help would be appreciated.
Regards
Marcel
Please check with a light bulb if the speed controller works correctly (adjust from 0 to 100%).
If it works correctly, then most likely the motor is not suited for control with this device.
