H31NLEB-LNN-NS-00 by Kollmorgen

The Kollmorgen H31NLEB-LNN-NS-00 hybrid motor integrates seamlessly into the H Hybrid Motors lineup by Kollmorgen, delivering a robust solution for precision motion control in industrial automation. This NEMA 34 device, with a Frame Size: NEMA 34 (3.38 in dia) and Basic Size: Standard Construction, leverages a Configuration: Unipolar winding architecture to optimize electrical performance. Rated for a continuous Rated Current: 4.2 A, the motor provides predictable operation under varying load conditions. Electrical characteristics include a Phase resistance: 0.50 ±10% Ohms and a Phase inductance: 1.6 mH, ensuring stable current regulation and minimal overshoot during switching events. Constructed with a Rotar type: Laminated rotor and a Number of Rotar stacks: 1 stack configuration, this motor achieves high efficiency and low eddy-current losses. The device’s Shaft modification: Smooth (Size 2,3) only design supports straightforward coupling and alignment in compact system layouts.

Performance attributes of the H31NLEB-LNN-NS-00 emphasize controlled torque delivery and thermal management. The motor generates a Holding torque: 1.12 ±10% Nm, enabling reliable holding and positioning in static or low-speed applications. A thermal resistance: 3.9 °C/Watt rating ensures predictable heat dissipation, even under sustained operation at full load. The laminated rotor construction reduces inertia and improves dynamic response, while the single rotor stack simplifies manufacturing consistency and maintenance procedures. Clocking losses are minimized through the unipolar winding scheme, which also reduces driver complexity for direct current drive topologies. At a weight of 156 kg, the motor balances structural rigidity with the mass necessary to dampen micro-vibrations, enhancing motion smoothness in precision assemblies.

Designed for seamless integration into industrial systems, the H31NLEB-LNN-NS-00 features a splashproof terminal board compatible with inch NPS conduit connectors for secure electrical connections. Its smooth, single-shaft configuration accommodates a variety of mounting brackets and couplings common in factory automation. The absence of onboard feedback electronics allows direct interfacing with external position encoders or open-loop driver architectures, preserving system-level flexibility. With a sturdy laminated rotor and proven unipolar topology, this motor delivers consistent performance across temperature and environmental fluctuations. Ideal use cases include pick-and-place machinery, indexing tables, and general-purpose motion stages where precise holding torque and repeatable positioning are essential.
