Q: How do I choose a suitable stepper motor for my application?

A: There are several important criteria to consider: holding torque, physical size (NEMA size, length of motor etc.), supply voltage, and supply current etc. Once you determine these key criteria, we can find a suitable model for you. Feel free to contact us, we are more than happy to help you with the selection process.


Q: I need a non-standard motor for my application, can you help?

A: Certainly, most of our customers request custom configurations in one form or another. If you plan on replacing a motor in an existing application, just send us a drawing or sample and we can help you find a suitable replacement. Alternatively, contact us and describe your application, our engineers will work with you to create a solution tailor-made for you.


Q: Do you have any products in stock? Can I order samples first?
