    Default MC-60 treadmill speed controller (controller needs a load ?)

    Any help will be greatly appreciated. I have an MC-60 treadmill speed controller. I'm mounting the motor on a drill press. I put switch on the wipe terminal on the pot and added a reverse switch on the motor leads. I have it geared way down so that I can do some thread tapping. I'd like to have it start and stop immediately. I'm trying to eliminate the soft start and stop. Putting a switch from the board (red wire to the motor) gives me what I'm looking for but I am concerned about whether the board needs the load from the motor. Is it safe for the speed controller to run with a switch on the motor lead?

    I'm no expert, but as you asked for "any help", is it possible to use a simpler controller? Such as:

    I'm not exactly sure what you mean by a switch in line with the wiper.
    But how about a switch from the wiper to the 'low' side of the pot - that would have the effect of turning the speed down to 0 instantly, without switching high currents.

    Ps, what sort of treadmill motor runs on 50 volts - I've only seen 90 or 180, but I guess if you only want relatively low output that wouldn't matter.
