Product Description:

The H22NRNC-JNN-NS-00 is a hybrid stepper motor produced by Kollmorgen as a member of the H Hybrid Motors series. The unit combines permanent-magnet and variable-reluctance principles to create incremental torque for machine axes that require open-loop positioning, such as small conveyors, labelers, or syringe pumps. By converting pulse trains from a microstep drive into precise rotor increments, the motor provides a direct mechanical interface that eliminates gear reduction in many low-to-medium-torque applications. Its hybrid design supports controlled starts, stops, and directional changes when paired with a compatible stepper drive.

The frame follows NEMA 23 geometry, so the four-bolt face and pilot diameter fit common 57 mm mounting patterns. The windings use Class B insulation rated for 130 °C, enabling continuous service near elevated cabinet temperatures. Insulation resistance between the windings and frame is 100 megohms at 500 V, helping protect control circuits from ground faults. The insulation system tolerates transients of up to 340 VDC from chopper drives. An ambient operating range of -20 °C to +40 °C permits installation in cold-storage equipment or standard indoor machinery without derating. Lead-wire terminations simplify connections to terminal blocks, while the standard housing provides basic protection for the internal components.

The laminated core is arranged in two stacks, balancing axial length against torque output for moderate-inertia loads. Each full step advances the shaft by 1.8 degrees, producing 200 full-step positions per revolution. A compatible microstepping drive can subdivide each full step to produce smoother movement and reduce low-speed vibration. Positional deviation remains within ±1.5%, supporting repeatable indexing in print heads and optical tables. The smooth shaft accommodates clamping couplings or compression fittings without requiring a keyed connection. The standardized mounting face helps maintain alignment between the shaft and the attached load. Lead wires exit the housing in a regular arrangement that supports direct routing to a drive or terminal block.
