    Default ID'ing Stepper Motor

    Can anyone shed any light on the model of this Stepper Motor?
    I've googled, the lower number( and parts of ), 'Tianya' and even tried searching for the logo....all failed.
    Its a larger stepper, suspect NEMA 34?

    The stepper driver blew up and I have fitted a new driver and now the motor is grumbling and not traversing.........I'm thinking one blew the other one up but don't know why or who died first.

    Steve

    Do the dimensions match with the 450A on this page?

    Nema 86?

    I would think more around a Nema 34 or 42 depending on what you measured:

    Slowing 104.200.25.14&c=1&t=45155.2092141204

    Any generic stepper motor with similar specs should do as a replacement.

    Probably one of the coils is damaged which is why it’s stuttering or it could be a bad MOSFET on the driver board.

    What machine does this belong to?

    You got me....I had a brain f##t, of course its a NEMA 34. I have edited the original post.....

    I found one of the motor coil wires loose in the terminal block. Looks like it was never fitted properly. All working now.

    Machine is from China, A Minglan 9060.
