Product Description:
The E22SSLT-LNN-NS-03 is a hybrid stepper motor built by Kollmorgen for the E Hybrid Stepper Motors series. With a laminated rotor and SIGMAX magnetic construction, the unit provides incremental motion in response to digital command pulses. It is commonly installed in small conveyors, laboratory pumps, and pick-and-place actuators where open-loop position control and moderate holding torque are required. The round frame couples directly to standard motor mounts, and the smooth shaft simplifies connection to timing pulleys or couplings.
The motor advances by 1.8 degrees per input pulse, so a full electrical sequence delivers 200 mechanical steps per revolution. This discrete movement supports predictable positioning without requiring a feedback device. Its NEMA 23 frame has a 2.25-inch face dimension and a 1.86-inch pilot register, allowing interchange with other motors in the same size class. The electrical insulation meets Class B thermal limits at 130 °C, permitting continuous winding temperatures well above typical ambient conditions without loss of dielectric strength. A winding withstand rating of 340 VDC supports use with high-voltage microstepping drives while maintaining a margin against turn-to-turn breakdown.
The permitted ambient temperature ranges from -20 °C to +40 °C, so the motor can operate in unconditioned equipment rooms and chilled enclosures. The windings have an insulation resistance of 100 megohms, minimizing leakage current when moisture is present. Power is supplied through a four-lead series connection, enabling simple bipolar drive configurations and full-stack energization across the motor’s two stator sections. Position repeatability remains within ±1.5% of each commanded step, which supports light indexing duties when no feedback device is installed. The dual-stack layout balances holding-torque requirements with the rotational inertia needed for controlled starts and stops.
