Functional Features:

Hybrid stepping motor combining the high torque density of permanent magnet and variable reluctance designs
Low-speed torque optimized winding for applications requiring high holding torque at lower rotational speeds

Application Scenarios: Suitable for industrial automation systems, indexing tables, valve control, small conveyor positioning, and other applications requiring accurate incremental motion under moderate load conditions.

Working Principle: As a hybrid stepper, the motor divides a full rotation into a large number of discrete steps. An external stepper drive energizes the stator windings in a precise sequence, causing the rotor (with both permanent magnet and toothed salient pole construction) to advance incrementally. Each pulse from the controller advances the rotor by one step angle.

Installation Requirements: Mount using the NEMA 23 standard face mounting pattern with the special mounting configuration as specified. Ensure proper alignment with the coupling or load. The motor requires a compatible microstepping drive for operation.

Usage Precautions: Because detailed torque-speed curves and electrical ratings are defined by the specific drive used, the motor must always be paired with a Pacific Scientific / Kollmorgen approved stepper drive matched to the E22 series winding. Avoid exceeding the rated temperature and current limits to prevent demagnetization of the rotor.
