Product Description:
The H33HRFT-LNK-NS-00 hybrid stepper motor is built by Kollmorgen within the H Hybrid Motors series. Designed for industrial automation, it uses a regular leadwire connection arrangement and comes with standard construction. The motor seats on a heavy-duty NEMA mount, has a 3.38 in frame diameter, and uses three stacks. Its overall body length is 5.33 in, and the smooth shaft supports direct coupling. Eight leads permit wiring to unipolar or bipolar drives, while the winding is optimized for maximum torque at low speed. The unit weighs 7.6 lb, which keeps structural loading moderate.
The motor conforms to the NEMA 34 frame standard, giving a consistent pilot diameter and bolt pattern. Its static holding capability reaches 687 oz-in, allowing the shaft to remain in position when power is removed. Each command pulse advances the rotor by 1.8 degrees, and 200 pulses complete one full revolution. Position repeatability stays within ±1.5% of a step. Low-mass motion is supported by a rotor inertia of 0.025 oz-in-s², which helps keep acceleration transients short. The 22 AWG lead set simplifies termination while maintaining current capacity. Electrical insulation is rated at 100 Megohms and withstands 340 VDC, isolating the drive electronics from the chassis. A thermal resistance of 2.0 °C/Watt shows how quickly winding heat moves to the frame during duty cycles.
The bearing system tolerates up to 180 lb of axial force and 35 lb of radial force, allowing couplings or pulleys to be mounted without exceeding L10 life assumptions. Continuous operation remains stable in ambient temperatures from -20 °C to +40 °C, and the windings use a Class B, 130 °C insulation system that resists thermal aging during high-cycle positioning. The motor can be used in conveyors, index tables, or gantry axes where end thrust, side belt pull, and changing room temperatures are present.
