Product Features 2-phase hybrid step motor High torque design Standard NEMA 23 dimensions Series or parallel wiring Not available for new applications. Please call for assistance selecting a replacement.1-800-525-1609 Product Details Vertical Tabs DescriptionThe HT23-401 stepper motor is no longer available. The recommended replacement motor is the HT23-601. The HT23-401 stepper motor is a two-phase hybrid step motor with a NEMA 23 frame size. It is terminated with 8 motor leads, meaning it can be connected in a few different ways including bipolar series and bipolar parallel.
