Product Description:

The H33NRFC-LNW-NS-00 is a hybrid stepper motor built by Kollmorgen and supplied through the H Hybrid Motors series. It fits the NEMA 34 frame standard and converts digital pulse commands into incremental rotary motion. Its laminated rotor and single smooth shaft support controlled movement in pick-and-place heads, small conveyors, metering pumps, and other industrial automation equipment.

The motor housing measures 3.38 in across, giving it the footprint associated with its frame size while leaving room for mounting hardware. Each full step covers 1.8 degrees, allowing precise open-loop positioning when the motor is paired with a suitable drive. Power enters through eight flying leads that use 22 AWG conductors, balancing current capacity with the flexibility needed for routing through machinery. The stator windings use Class B insulation rated for 130 °C, supporting operation within the permitted winding temperature limit. The insulation resistance is at least 100 megohms when measured under ambient test conditions, helping limit leakage current that could interfere with nearby control circuits.

The rotor provides 200 full steps per revolution, while the three-stack lamination arrangement helps reduce torque ripple during slow movement. The winding insulation withstands a hipot test voltage of 340 VDC, allowing it to tolerate drive overvoltages that can occur during regenerative deceleration. The permitted operating temperature range is -20 °C to +40 °C, making the motor suitable for unheated storage areas and lightly ventilated control panels. Overall body depth does not exceed 5.06 in, helping limit the space required behind the mounting surface. The flying leads have a minimum length of 12 inches, providing sufficient reach for strain-relieved electrical terminations without placing excessive tension on the conductor entry point.
