It has been superseded by the HT23-554. The HT23-550 two-phase stepper motor is designed for use with high-voltage stepper drives like the STAC5 and STAC6 series (120 VAC input versions only) and is suitable for a wide range of motion control applications. The motor comes with an integral 10 ft shielded cable and a preassembled drive connector. When not used with STAC5 or STAC6 drives, the preassembled drive connector can be removed to reveal 8 motor leads plus 1 ground lead. The 8 motor leads can be connected in one of three ways to the step motor drive of your choice: bipolar series (required for STAC5/STAC6 drives), bipolar parallel, or unipolar. This motor has features which do not conform to standard NEMA for gearhead ordering purposes. Stated lead time for a gearhead ordered with this motor may be longer than shown. Please call for delivery on a gearhead being ordered with this motor.
