Request Information
The series 123-1 (2.3 inch diameter) permanent magnet step motors is available in 7.5 degree or 15 degree step angles, and can be wound for bipolar or unipolar drives. Motors that are wound for Bipolar drives can be run from an AC voltage source, using a capacitor to create a phase shift in the line voltage. This method creates a simple, low cost, reversing drive. Series 123-1 step motors can be custom wound for any voltage up to 240 V. Custom shafts and connectors are available.
