 I have a DC motor controlller here, power from AC. When the motor is run=
ning really fast and I press the off button at the controller side, it sl=
ows down to near stop, but "click" at the relay, and starts spinning agai=
n, which is quite dangerous. However, this does not happen when the motor=
 is running slow. I bet it is because of the motor back emf. But how can =
I take that effect away?
