Re: IAC motors

[steve ravet <sravet@arm.com>]

Ken -- the IAC motor is a stepper motor, which requires pulses to be
given in a particular sequence to the different wires in order to move
the spindle.  There are different types of steppers, and I don't know
what kind the IAC is, so I can't tell you anything further, other than
to check out this WWW page which has lots and lots of info about stepper
motors.
