E22NRFC-LNN-NS-00

The Kollmorgen E22NRFC-LNN-NS-00 stepper motor is a high-precision, industrial-grade actuator within the renowned E Hybrid Stepper Motors series, designed and manufactured by Kollmorgen to meet demanding motion control requirements. This model features a part_number of E22NRFC-LNN-NS-00 with a compact NEMA frame size of 23 and a maximum overall length (L Max.) of 77.7 mm for space-constrained installations. Engineered for precise motion, the motor delivers Full steps per Revolution of 200 with a Step Accuracy % of ±1.5 % ensuring repeatable positioning in closed-loop and open-loop systems. It incorporates an 8-lead winding configuration that allows flexible wiring options for 6-lead, 4-lead series, or 4-lead parallel connections. The robust design also includes an Insulation Resistance of 100 Megohms and an Insulation Voltage Rating of 340 Vdc to ensure electrical safety and durability in harsh environments.

Performance is optimized through advanced hybrid construction and patented Sigmax Technology, which directs magnetic flux from high-energy rare-earth magnets into precisely engineered stator tooth gaps. The double rotor stack design produces higher flux density and superior torque output relative to conventional motors of similar size. In a 6-lead configuration, the motor achieves a Holding Torque (6-lead) of 1.09 Nm at a Rated Current (6-lead) of 4.5 A DC, while the 4-lead series option boosts Holding Torque (4-lead series) to 1.54 Nm at 3.2 A DC. In 4-lead parallel mode, the device maintains the same 1.54 Nm torque level but delivers a higher Rated Current (4-lead parallel) of 6.4 A DC for rapid acceleration profiles. The multiple lead configurations enable users to tailor the motor’s electrical characteristics to specific speed-torque curves, minimizing power consumption without compromising dynamic response.

Designed for seamless integration, the E22NRFC-LNN-NS-00 offers standardized NEMA mounting provisions and compatibility with industry-leading stepper drives and motion controllers. The high Insulation Voltage Rating and robust winding insulation contribute to long-term reliability under continuous duty and frequent start-stop cycles. This motor excels in automation, packaging machinery, semiconductor equipment, medical devices, and robotics, where precise indexing and smooth motion are critical. Its compact footprint and flexible lead options simplify retrofits and new system designs, reducing development time and cost. With Kollmorgen’s reputation for quality and the proven reliability of the E Hybrid Stepper Motors series, this model is an ideal choice for demanding industrial applications where performance, adaptability, and longevity are paramount.
