What would be necessary componets in a system that measures voltage, and at a certain voltage, engages or disengages a motor? How would this work? Thanks.

To get you started:

You would begin with a comparitor, one input would be referenced to a voltage that you want the output to "trip" at. The second input would be where you apply your "voltage" that you are using to start the motor.

The output of the comparitor would go to a buffer/driver that would be able to turn on a relay that would engage/disengage your motor.
