Product Description:

The E32NRHA-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. It is intended for incremental positioning and controlled speed operation in automated machinery, converting pulse commands from a micro-stepping drive into discrete shaft movement without an internal feedback device. By combining SIGMAX magnetic construction with a two-stack rotor, the motor delivers high torque density while retaining a standard mounting pattern that fits common conveyor, gantry, and feeder layouts.

The motor uses a NEMA 34 frame and a regular leadwire interface with four parallel leads, so connection to most open-loop drives is direct. Each phase draws 5.6 A and produces a holding torque of 4.43 N·m to maintain shaft position when pulse output stops. Its phase inductance of 3.7 mH and phase resistance of 0.39 Ω influence the driver voltage needed for fast current rise. A basic step angle of 1.8 degrees gives 200 full steps per revolution, and intrinsic accuracy stays within ±1.5 percent to limit cumulative positioning error over long travel. Rotor inertia is 0.120×10⁻³ kg·m², while a thermal resistance of 2.7 °C/W and Class B insulation rated to 130 °C support continuous duty when winding temperature remains below the 340 Vdc insulation test level. Insulation resistance is 100 MΩ, which provides solid electrical isolation in humid environments.

A smooth shaft transmits motion and can withstand axial loads of up to 801 N and radial loads of up to 156 N, allowing the motor to handle belt tension or pinion side loading without external support bearings in many applications. The housing length is 95.5 mm, and the motor mass of 2.40 kg keeps it manageable for light equipment plates and compact machine sections. Permissible operating temperatures range from −20 °C to +40 °C, so the unit can run in most factory environments without additional climate control.
