Product Description:
The E31NCLP-LDN-NK-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. Designed for incremental positioning tasks, the unit converts pulse trains from an indexer or drive into discrete shaft movement so machine tools, pick-and-place gantries, or packaging equipment can achieve repeatable motion without feedback devices. Its SIGMAX construction concentrates magnetic flux to provide higher torque in the NEMA 34 frame, while the smooth shaft simplifies direct coupling to belt pulleys or rigid couplings in automated assemblies.
This motor supplies a holding torque of 2.43 N-m, allowing stationary axes to resist external disturbances when the coils are energized. Motion is divided into discrete increments by a 1.8° step angle, which yields 200 full steps per revolution with an accuracy of ±1.5%. Each phase draws 4.2 A under rated conditions. The winding has a resistance of 0.52 Ω, which affects copper losses, and an inductance of 4.4 mH, which influences current rise time during high-speed operation. These electrical characteristics allow microstepping drives to modulate current smoothly and maintain torque at elevated pulse rates. The rotor inertia of 0.0083 oz-in-s² supports responsive acceleration during frequent positioning cycles.
The shaft can accept an axial load of 801 N and a radial load of 156 N without exceeding the bearing load limits, allowing belt tension or gear forces to act directly on the output. The Class B insulation rated to 130 °C withstands winding temperature rise during operation. The permitted operating temperature range is -20 °C to +40 °C, allowing use in many factory enclosures without additional temperature control. A System MS connector provides the electrical interface for the motor. The motor also uses a single lamination stack and a four-lead series wiring arrangement for installation with compatible NEMA mounting patterns. Its insulation system withstands 340 VDC and provides 100 MΩ of resistance between the windings and frame.
