Designed by Pacific Scientific for demanding automation environments, this NEMA 42 frame motor features bipolar parallel winding configuration to optimize torque output and thermal efficiency while maintaining smooth operation. With a power rating of 425 W and a current rating of 9.9A, the N42HLEM-LNK-NS-01 offers sustained high torque for complex motion profiles. Its IP 65 protection class ensures reliable operation in dusty or wet conditions, making it suitable for harsh industrial settings where environmental resilience is critical. This motor’s combination of high power density and rugged design enables extended service life under continuous operation.

Detailed technical specifications define the N42HLEM-LNK-NS-01’s electrical and mechanical parameters with precision. The motor operates at a nominal speed of 1500 RPM and a step angle of 1.8°, yielding accurate 1.8-degree increments for fine positional control. Rated at 170 V≫, the motor’s insulation voltage rating of 340 Vdc supports high-voltage drive systems. The Laminated rotor design and 340 Vdc insulation rating improve response times and thermal stability during high-speed operation. A 1/2 inch shaft diameter with straight key shaft feature and integrated shaft seal deliver secure mechanical coupling and effective protection against contaminants. The 6 lead leadwire configuration simplifies wiring options for unipolar or bipolar drive schemes, while the heavy duty NEMA mounting type supports robust mechanical integration.

Operational features highlight the motor’s performance under load and its adaptability to various control architectures. The bipolar parallel winding≫ enables higher torque at lower currents compared to series winding alternatives, reducing driver stress and enhancing efficiency. With a stack length of 2 stacks, the rotor achieves increased torque density without significant penalty in inertia. The single shaft design provides straightforward coupling to gearboxes or direct-drive systems, while the absence of an encoder (No feedback) minimizes cost for open-loop applications. A conduit thread of 1/2 in. NPSC pipe thread and splashproof connection style via conduit to terminal board ensure secure electrical connections and protection against ingress. This configuration supports smooth acceleration to 1500 RPM while maintaining precision and reliability.

System integration is simplified through standardized mechanical and electrical interfaces. The N42HLEM-LNK-NS-01 seamlessly integrates with industry-standard stepper drives and PLC-based motion controllers used in packaging, labeling, CNC tools, and pick-and-place systems. Its IP 65-rated housing and robust construction guarantee dependable performance in food processing, pharmaceutical, and outdoor automation applications where washdown and dust are concerns. Engineers benefit from Pacific Scientific’s comprehensive support documentation, facilitating rapid deployment and parameter tuning in complex motion control networks.
