Product Description:

The E31NRLP-LSN-NS-03 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. As a two-phase actuator, it indexes machinery one magnetic detent at a time, supplying incremental motion control without an onboard feedback device. Its NEMA mounting interface permits direct installation on standardized brackets. The SIGMAX rotor concentrates magnetic flux to increase usable torque for positioning tables, labelers, and light conveyor axes in industrial automation.

The single-stack rotor develops a holding torque of 2.43 Nm, and every command pulse turns the shaft by 1.8 degrees. One complete revolution requires 200 discrete steps. Each phase draws 4.2 A through a coil resistance of 0.52 ohms, while the phase inductance of 4.4 mH affects current rise time and high-speed operation. The NEMA 34 frame contains a laminated rotor, a smooth output shaft, and four lead wires arranged in a series configuration for connection to a microstepping drive. A standard lead-wire connection simplifies cable routing where space is limited, and the lack of feedback reduces the number of required conductors. Continuous operation is permitted from -20 °C to +40 °C. Heat generated within the windings passes through the stator along a thermal path rated at 3.9 °C/W.

The electrical insulation is rated as Class B for temperatures up to 130 °C. Insulating material separates the windings from the frame and provides a resistance of 100 megohms, while the varnish withstands voltages up to 340 VDC without breakdown. Positional accuracy remains within ±1.5% of each commanded step, supporting indexing duties that cannot tolerate significant movement error. The single-stack design limits motor length and rotor inertia, which supports responsive acceleration in compact motion systems. Its maximum-torque-at-high-speed winding option supports higher supply voltages and extends the available operating speed when the motor is paired with an appropriate drive.
