Product Description:
Kollmorgen manufactures the E22NRLP-LNS-NS-02 as part of its E Hybrid Stepper Motors series. This two-phase rotary actuator converts drive pulses into controlled angular increments, giving packaging, semiconductor, and light-assembly equipment a direct means of indexing loads without closed-loop sensors. By advancing a laminated rotor stack in repeatable steps, the motor lets PLCs achieve position control with simple pulse trains and minimal interface hardware.
The motor uses a NEMA 23 frame with a 2.25-inch outside diameter and standard NEMA mounting holes. Each command pulse turns the shaft 1.8 degrees, so a full revolution contains 200 discrete steps. Angular error stays within ± 1.5 % of one step, supporting repeatable open-loop positioning. The windings use a bipolar series circuit connected through a four-lead harness with the standard lead-wire arrangement. The conductors are colored black, orange, red, and yellow for clear phase identification. Two rotor stacks supply torque, while a single smooth shaft simplifies coupling to compatible mechanical loads. SIGMAX magnetic construction reduces leakage flux, and the laminated rotor improves dynamic response during acceleration and deceleration. The max-torque-at-high-speed winding profile sustains output at elevated rotational speeds. No feedback device is fitted, so the drive sequences the motor strictly through commanded waveforms.
The permitted operating temperature ranges from -20 °C to +40 °C. A Class B dielectric system rated for 130 °C provides thermal headroom under continuous duty. Insulation resistance measures 100 megohms at 500 V, helping prevent unwanted current flow between electrically isolated parts. The insulation also supports a working potential of 340 VDC, allowing operation with common microstepping drives. A molded stator jacket channels heat through the steel frame to limit temperature buildup during extended operating cycles. This heat-transfer path helps maintain stable winding behavior as the motor repeatedly starts, stops, and changes speed in automated machinery.
