[sci.electronics] Stepper Motor Short Q

schriste@uceng.UC.EDU (Steven V. Christensen) (09/16/90)

Hi,
	I took apart an old hand-held scanning laser bar code
reader, and the motor which controlled the multi-fasceted mirror
(which moved the beam across) says "step 15(degrees)" on it, and has
4 wires - red, black, yellow, gray. I assume some kind of sequential
voltages on the wires makes it turn.

	Can anyone tell me more on how to operate the motor?

		Thanks,
		  Steven
