Internal Product Review
The E33HRHT-LNK-NS-00 is a Kollmorgen hybrid stepper motor with NEMA 34 frame sizing and a heavy-duty NEMA mounting style. A 975 oz-in holding torque paired with a 1.8-degree step angle supports strong low-speed positioning and confident indexing. Max-torque-at-low-speed winding and 5.1 A DC rated current make the unit an excellent choice for demanding motion axes.

Product Description:
The E33HRHT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. As a three-stack, high-torque actuator, it translates digital pulse trains from an indexer or microstep drive into precise rotary motion for positioning tables, pick-and-place heads, and other industrial axes. Its SIGMAX magnetic construction provides high torque density, while the heavy-duty NEMA mounting interface simplifies installation in existing machinery.
With a holding torque of 975 oz-in, the motor can hold loads in position while power is applied, and its NEMA 34 frame provides a 2.875-inch pilot for rigid face mounting. Each full step covers 1.8 degrees, yielding 200 discrete positions per revolution with a step accuracy of ±1.5%. The two phase windings draw 5.1 A DC in parallel and have a resistance of 0.61 ohms, supporting operation with high-current, low-resistance drives. A detent torque of 64 oz-in provides passive holding force when the windings are not energized. The rotor inertia is 0.0250 oz-in-s², balancing responsive acceleration with mechanical damping. The smooth 0.500-inch shaft extends 0.875 inch beyond the front face for direct coupling to gears or timing pulleys.
The winding inductance is 7.1 mH, which affects the electrical time constant and should be considered when selecting microstepping drive settings. At 7.6 lb and 5.33 inches in overall length, the motor has a compact profile for space-limited industrial equipment. It supports operation at ambient temperatures from -20 °C to +40 °C, and heat passes through the lamination stack with a thermal resistance of 2.0 °C/W. The internal insulation is rated Class B at 130 °C and has an insulation resistance of 100 MΩ. A dielectric withstand rating of 340 VDC helps protect the windings from electrical breakdown during continuous operation. Four lead wires provide parallel access to the motor phases, and the regular lead-wire arrangement simplifies connection to a compatible drive.
