Applied Motion HT23-401 is a NEMA 23 high torque step motor rated 264 oz-in holding torque bipolar. Applied Motion has discontinued the HT23-401. The recommended replacement is the HT23-601, same NEMA 23 frame and 2.99 in length. The HT23-401 specs stay on this page so you can check the swap. Applied Control represents Applied Motion Products in Michigan. Send the part number and quantity and we quote the HT23-601.

Shaft and encoder versions
HT23-401 is the single shaft motor. HT23-401D adds a rear shaft for a brake, handwheel or encoder. The datasheet lists these encoder equipped versions: HT23-401D-ZAA. Ask for the one you need with the quote and we confirm the encoder resolution and output.
Picking the winding
Bipolar parallel gives the most torque at speed and draws the highest current. Bipolar series draws half the current and holds torque better at low speed. Unipolar is for drives that need it. Set the drive current to the figure in the table for the connection you wire. Torque speed curves for each connection are on the datasheet.
Drives
Applied Motion step drives (STAC5, STAC6, STR and ST series) and StepSERVO closed loop drives run these motors. Tell us the supply voltage, the controller or network and the move profile and we pick the drive with the motor. More on the line at Applied Motion Products stepper and servo motion and the Applied Motion collection.
