Do i need to use this output from my DC motor speed control board?
With the goal of using the DC treadmill style motor that i have in a project (or two), i have baught a SCR speed control board.
The circuitry of the control board has outputs for the armature and field coil (labeled "excitation"). But the motor that i have is a permanent magnet type (2 wires going in / out - red and black - nice and simple). So i don't need the 'excitation' output. My question is whether the control board needs this to be used? Am i going to fry my brand new controller if i only draw current through the armature output? I could, for instance, put a resistive load accross this output to make it use just less than the output it's rated for.
Here's more info on the parts in question:
The speed controller is like this: http://www.ebay.com/itm/DC-0-220V-Continuous-Adjustable-Dc-Motor-Speed-Regulator-Control-Board-1000W-/251600102759?pt=LH_DefaultDomain_0&hash=item3a9488e567

The motor is either of the models on this page (i actually have one of each): http://www.ectrade.com/Auction/FreeSample/1931851586/Electric_treadmill_motor_DC-specific.html
Thanks in advance.
