Damaged Motor

[YAN-1]

Hello everyone. I have a linear stepper motor. I think I overloaded it and suddenly it is behaving in a weird way. As soon as any load is applied to it now, it starts reversing direction several times until the load is removed. :cry:
I'm not sure if the motor itself is damaged or if there is something wrong in the driving circuitry. Which is more likely and how can I know and/or solve the problem? Thanks a lot.

I suggest you try measuring the resistance of the windings, see if they are all the same. But I would suspect it's more likely to be a damaged driver?.
