Product Description:

The H34HRFA-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the H Hybrid Motors series. This motor converts digital drive pulses into discrete angular movement, allowing indexers, conveyors, and small gantry axes to position loads accurately without a separate feedback device. By combining permanent-magnet and variable-reluctance principles, it provides high detent torque that supports repeatable incremental rotation in automation tasks.

Mechanical dimensions include a body diameter of 3.38 in and an overall length of 6.58 in, giving the motor a compact cylindrical envelope for tight panels. Its frame conforms to the NEMA 34 standard, which uses a common mounting hole pattern and pilot register for installation on heavy-duty brackets. Four rotor stacks and standard construction raise the holding torque to 888 oz-in, helping the motor hold static loads when excitation is present. A full-step angle of 1.8 degrees and a step accuracy of ±1.5% produce 200 full steps per revolution, which simplifies microstepping calculations. A smooth, hardened shaft with a diameter of 0.5000 in extends from the front face, and eight lead wires allow series or parallel phase wiring to match drive current limits.

The insulation system uses Class B, 130°C limits, allowing the windings to operate safely in ambient temperatures from −20 °C to +40 °C. Electrical isolation includes an insulation resistance of 100 Megohms and a hipot capability of 340 Vdc, supporting use with standard low-voltage drives. Dynamic response is influenced by a rotor inertia of 0.035 oz-in-s², which helps the motor accelerate quickly while limiting sensitivity to small load changes. The motor weighs 9.7 lb, and the heavy-duty mounting flange helps maintain alignment under side loads. Lead wires exit through a molded strain relief at the rear housing, and the regular construction keeps the exterior smooth for airflow in fan-cooled cabinets.
