Is it better to run motors at 110 or 220?


	Theoretically, it doesn't make any difference.  However, there
	is a difference is the amount of power lost in the supply
	wiring.  All things being equal, a 110V motor will lose 4 times
	more power in the house wiring than a 220V motor.  This also
	means that the startup surge loss will be less, and the motor
	will get to speed quicker with 220V.  And in some circumstances,
	the smaller power loss will lead to longer motor life.

	This is usually irrelevant unless the supply wires are more
	than 50 feet long.
