TF and the wire
At the factory where I work, we have a machine with a pair of motors that traverse a couple of guides across a machine using push buttons. They are connected to a PCB containing 6 relays and 7 diodes. The external connections to this board are the push buttons, a 120v AC supply and the motors.
The PCB has failed and I am looking at replacing it with hard wired relays or contactors. It looks like all the board does is switch the 120v through to the motors to make them travel in either direction.
The motors are US made and have a label "AC synchronous stepper motor". I am trying to figure out how to connect to the motors. Each has 3 connections, and the drawing shows 2 windings in each motor, one end of each winding is connected to a common connection. the other ends are to their own terminal.
How is the 120v applied? How is the motor reversed? In GB a stepper motor would require a drive full of electronics, transistors etc and a synchronous motor would have different connections to what are on our motors. So I am thinking the terminology is different across the atlantic.
