Guide to Stepper Motor Drive Selection

Q: How can I work out which stepper motor drive I need?
A: If you are new to these products we suggest that you start by reading our technical guides to stepper motors and stepper motor drives. These may be downloaded through the Technical section of this website. With this overview you will then need to review the motor and drive product ranges, e.g., unipolar or bipolar drive mode, drive voltage and current, size and style of drive etc.

Q: Are your products suitable for worldwide use?
A: In general, yes, as they are DC powered and designed to International Standards.

Q: Are the products compliant with EU safety standards and directives?
A: Yes, we apply all relevant European Directives to our designs, and where appropriate, carry out EMC testing in independent laboratories.

Q: Are the products compliant with the RoHS Directive?
A: Our materials and manufacturing processes were converted to RoHS-compliance several years ago. All of our current products are fully RoHS-compliant.

Q: Do you accept credit card payment for goods?
