Product Description:

The H34HRFT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. As a two-phase device with discrete step positioning, it converts pulse commands from an indexer or drive into incremental mechanical rotation for pick-and-place modules, small conveyors, and other motion axes in industrial automation. The frame, windings, and shaft dimensions follow standardized NEMA guidelines, allowing use with common motion components while maintaining Kollmorgen’s manufacturing tolerances for repeatable positioning.

With a frame size of NEMA 34, the unit fits mounting patterns common to medium-torque machinery. Its holding capability reaches 882 oz-in, so static loads can be restrained without a brake. Each electrical pulse advances the shaft by 1.8 degrees, and 200 such increments complete one revolution. The motor therefore has 200 steps per revolution. Continuous service is permitted between -20°C to +40°C, matching many indoor equipment envelopes. The Class B insulation system tolerates winding temperatures to 130 °C, and the insulation resistance is 100 megohms to limit leakage current. An insulation voltage rating of 340 Vdc supports unipolar or bipolar drives. Eight lead wires exit the regular lead-wire outlet, allowing series or parallel phase wiring to trade speed for torque.

The motor can sustain an axial force of 180 lb and a radial force of 35 lb without exceeding bearing ratings. A low rotor inertia of 0.035 oz-in-s² supports rapid index cycles while limiting drive current spikes. Overall mass is 9.7 lb, and the cylindrical body diameter is 3.38 in with a maximum length of 6.58 in. Thermal resistance of 1.7 °C/W describes how quickly internal heat moves to the housing, and the smooth 0.5000 in shaft simplifies coupler selection for pumps, slides, or belt drives.
