Source of Stepper Motors

I'm helping a friend with a prop (as in theatrical prop, not the Propeller -- though we will use the Propeller to run it!) that requires two stepper motors. I'm looking for a reliable source of steppers as he may need to build several if all works out. Thanks!

    Jon,

    I've never bought stepper motors except as surplus, due to the price differential vs. new. Assuming the latter is what you're looking for, however, try Stock Drive Products/Sterling Instruments:

    What kind of other properties do you need in the motor?

    What size of stepper do you need? I've got a couple dozen NEMA 34 from EAD (Eastern Air Devices).

    If you are looking for options and want to buy from a place that will be around for a while, try Automation Direct. Been very happy with them for steppers and PLCs for various pieces of equipment since ~2002.

    Much depends on the size stepper motors you need.. big powerful ones have an array of industrial suppliers.

    But for the small tiny ones with good controller support... try Pololu. They have an excellent selection with related hardware and all are 200 steps.

    Phil, thanks for the pointer, I'll take a look at them. Something that drives me crazy about buying used or surplus steppers is that the seller will often list the form factor (e.g. NEMA 23), but not the torque. Those guys look like they list both.

    Thanks for the feedback. Right now we don't know what we don't know and will probably make a prototype with motors I can pick up over at All Electronics. Long term, though, we'd rather go with a stable source.

    The project is a Ouija board gag. A Propeller circuit will allow an operator to select an answer and an XY arrangement underneath will move the puck to spell it out.The puck will be magnetically coupled with the carriage.

    I've heard that these were excellent for 3D Printers, so should be fairly stable and dependable: http://shop.evilmadscientist.com/productsmenu/partsmenu/187-stepper
