    tormach 1100 3 series stepper motor

    Hello, My buddy has a 1100 that's been updated to the 3 series Steppers. His x axis has locked up. Tormach says the soonest they will have a replacement is June 6. He is running production parts and needs to be up and running. Has anyone used another Stepper and if so could you point us in the right direction on getting him up and running? The stepper motor is seized, The leadshine 3ND883 driver is fine. Just need a suitable stepper replacement. Thank You

    I believe that they use 3 phase steppers

    Yes they are a 3 wire 3 phase stepper. Tormach wouldn't even give him the factory stepper ounce number. 600oz-800oz?

    3 phase steppers. X & Y are (or were in the bipolar steppers) rated at 640 oz-in, Z was twice that. Presumably the spec on the 3 phase is similar or slightly bigger.
