Product Description:

The E33NRFP-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen for the E Hybrid Stepper Motors series. Built on the NEMA 34 frame, it translates pulse commands from a drive into controlled incremental motion for positioning tables, cutters, or feeders on automated machines. The device accepts a standard NEMA mounting pattern and uses a regular lead-wire connection, making integration straightforward in retrofit and new-build control cabinets.

When wired in bipolar mode, it can resist static loads with 7.03 N·m of holding torque, allowing vertical axes to remain locked without external brakes. Angular resolution is set by a 1.8-degree step angle, so each revolution is divided into 200 full steps for repeatable indexing. In a series connection, the windings draw 4.0 A/phase, a current level suited to compatible stepper drives. The laminated rotor carries an inertia of only 0.025 oz-in-s², supporting rapid acceleration and deceleration in pick-and-place tasks. Torque is multiplied by the motor’s 3-stack magnetic structure, which lengthens the active core inside a 5.06-inch body without enlarging the faceplate. Eight 22 AWG leads exit the housing for series, parallel, or unipolar wiring, and a smooth shaft simplifies coupler or pulley attachment.

Thermal management is characterized by 2.0 °C/W of winding-to-ambient resistance, so temperature rise stays predictable during duty-cycle changes. Continuous operation is permitted from -20 °C to +40 °C, and the windings use Class B, 130 °C insulation to maintain dielectric strength under load. Insulation resistance is specified at 100 megohms at 340 Vdc to protect control electronics from leakage currents. Total mass is 7.6 lb, adding inertial damping when the motor is hard-mounted to machinery. Step linearity remains within ±1.5% thanks to SIGMAX construction and windings optimized for maximum torque at high speed.
