Stepper Motor Drives
- A range of bipolar and unipolar stepper motor drives
- Programmable models or simple step and direction
- Suitable for 4, 5, 6 and 8 lead wire stepper motors
- Phase currents to match NEMA sizes 11 – 42
- Open frame and cased models
The range of Astrosyn stepper motor drives includes cased and open frame models offering both bipolar and unipolar modes of operation and a range of current outputs from 0.2-10A. At the top end of the range we offer programmable bipolar drives.
Bipolar drives generally achieve the highest stepper motor speed/torque performance, while unipolar drives provide a cost effective solution for routine applications.
Microstepping is available in all models of bipolar drives.
