Product Features 2-phase hybrid step motor High torque design Standard NEMA 23 dimensions Optimized for high bus voltage $168.00 Add to Cart: HT23-550 ($168.00) Part Number w/ Single Shaft HT23-550D ($168.00) Part Number w/ Double Shaft Quantity U.S. & Canada Product Details Vertical Tabs DescriptionThe HT23-550 two-phase stepper motor is designed for use with the STAC6 series of stepper drives (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 for easy connection to a STAC6 drive. When not used with 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 STAC6 drives), bipolar parallel, or unipolar. Note: The HT23-550 step motor has been superseded by the HT23-554 step motor for use in all new applications with STAC6 stepper drives. 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.
