Denford stepper motor

[Clive S]

Thanks Clive, it would appear that it is the cable going into the motor, as it moves there must be a break in the wire, it looks like the wiring is connected directly to the windings so not sure if it’s the cable or the thin copper wire on the winding that’s the problem, I’ll have a look tomorrow, ��

Don't open the motor up. Did you check the ohms between each phase they should be around 1-2 ohms across each coil.

You are not giving any info back so it is hard to guess.
