Product Description:
The E32NRHA-LSN-NS-02 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. It integrates a laminated rotor and SIGMAX construction to concentrate magnetic flux, enabling stable detent torque and dynamic torque without feedback electronics. Used on pick-and-place gantries, metering pumps, and small indexers, the motor converts digital pulse trains from a drive into precise mechanical steps. Its open-loop design provides controlled positioning for industrial automation systems that do not require encoder feedback.
The motor fits the NEMA 34 frame envelope and mounts with standard NEMA hardware. At standstill, it delivers a holding torque of 4.43 N·m, allowing loads to remain locked while power is applied. Each phase is wound for a rated current of 5.6 A and has a resistance of 0.39 Ω and an inductance of 3.7 mH. These electrical values help determine the drive voltage and expected current ripple. Four parallel leads provide the standard lead-wire connection, allowing the motor to be wired in series or parallel bipolar configurations. Two stator stacks generate the electromagnetic field, and the smooth shaft transfers torque directly to a coupling. Because the motor has no feedback device, its response depends on the rotor’s inherent detent profile and the drive’s microstepping algorithm.
The electrical insulation withstands 340 VDC and has an insulation resistance of 100 megohms. The insulation system carries a Class B temperature rating of 130 °C, supporting operation with grounded or floating power supplies. The motor operates in ambient temperatures from -20 °C to +40 °C and dissipates heat through a thermal resistance of 2.7 °C/W. A step angle of 1.8 degrees provides 200 full steps per revolution with an accuracy of ±1.5%, allowing predictable indexing without an encoder. The laminated rotor core reduces rotational inertia, while the NEMA mounting flange supports installation with compatible machine hardware.
