Re: stepper

This is a two phase unipolar stepper motor.

term. 1 is phase "A" and term. 3 is phase "A NOT" with term. 6 going
to the current limiting resistor to the plus supply.

term. 4 is phase "B" and term. 5 is phase "B NOT" and term. 2 going
to the current limiting resistor to the plus supply.

I have worked with these type of stepper motors used in line printer
applications. The ones that I worked with were Slo-Syn model M061 and
M062 motors. The wiring for the larger M111, M112-FD, and M112-FJ
have screw terminals were the smaller one like I used have wire leads.

If the model numbers for the match the one of the number for the
larger stepper motors and are Slo-Syn I have the specs.
