- Bachman motors are designed to use DC only. The motor won't go anywhere when
- connected to an AC supply. It will try t osscillate back and forth. A DC motor
- relies on the current travelling in the same direction to maintain a direction
- of rotation. If AC were applied to it, it would try to oscillate. Also, the
- motor detemines the current draw. The motor will not draw 5 amps unless there
- is something seriously wrong with it. Most low quality motors like Bachmans
- draw only 2 amps or so under stall conditions.

- I think you need to brush up on your electronics a bit before you proceed.
