5 Wire Stepper Motor

Recommended Posts


Has anybody successfully operated a 5 wire stepper motor before?

It's fitted to a Rover T16 (Turbo) Engine.

It has 5 pins (well 6, but only 5 used)

Pin 1 (Channel 1)

Pin 2 +12v 

Pin 3 (Channel 2)

Pin 4 (Channel 4)

Pin 5 (Empty)

Pin 6 (Channel 3)

I suspect that internally the 12v supply is split to both pairs of the stepper.

Maximum movement of the stepper motor is 3.75 revolutions, and this is accomplished by 180 steps of 7.5°

Can this be operated by Link?

I assume if I can ascertain which pair is which I can wire it as a 6 pin stepper?
