Product Description:
The H33HLEC-LNK-NS-00 is a three-stack hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. Its housing follows NEMA heavy-duty mounting practices and has a 3.38-inch body diameter with a 6.73-inch overall length. The smooth shaft permits the use of direct clamp couplings, and the unit has a standard construction. Field wiring passes through a splash-proof conduit connector to an internal terminal board; the entry uses a 1/2-inch NPS pipe thread for flexible metallic conduit. Six motor leads exit the stator, and the triple-stack lamination supports high torque density while maintaining precise incremental motion.
Its electromagnetic profile centers on a holding torque of 466 oz-in, which supports inertial loads at standstill without external brakes. Each phase draws 7.8 A, while the copper network has a phase resistance of 0.29 Ω, minimizing resistive heating during continuous movement. With a full-step angle of 1.8°, the rotor reaches 200 discrete positions per revolution, and positioning error remains controlled when microstepping drives are used. Safe operation spans -20 °C to +40 °C, aided by a thermal resistance of 2.0 °C/W between the winding and frame. The phase inductance is 1.6 mH, which moderates the rate of current change. Electrical insulation meets Class B limits of 130 °C, provides an insulation resistance of 100 MΩ, and withstands a test voltage of 340 VDC. The rotor inertia is 0.025 oz-in-s², supporting rapid acceleration and deceleration.
The motor supports an allowable axial force of 180 lb and a radial load limit of 35 lb at the reference overhung distance. It mounts into machinery with a NEMA 34 frame outline and adds 7.6 lb to the carriage mass, which assists with the dynamic sizing of linear stages. Incremental position fidelity is supported by a step accuracy of ±1.5%, maintaining predictable repeatability across indexing cycles. The six-lead connection permits compatible series or parallel winding arrangements. Its splash-proof conduit entry protects the terminal board while allowing flexible metallic conduit to route the field wiring into the housing.
