Product Description:

The E32NRFA-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen for the E Hybrid Stepper Motors series. In automated machinery, it converts digital pulse commands from a drive into fixed angular movement for repeatable indexing on conveyors, pick-and-place axes, and light gantries. Its two-phase electromagnetic design holds commanded positions without external feedback in many applications, making it a practical choice for pulse-driven motion systems that need consistent incremental movement. Because step commands are translated directly into predictable shaft increments, the motor suits machines that rely on repeatable starts, stops, and short indexing moves rather than continuous high-speed rotation.

With a frame size of NEMA 34, the motor bolts directly to standard NEMA mounting brackets used in industrial equipment. Each full step covers 1.8 degrees, which gives 200 discrete rotor positions per revolution for straightforward motion scaling. The winding harness has 8 leads, so the motor can be wired in series, parallel, or half-coil arrangements to suit different voltage and current requirements. This wiring flexibility helps the motor adapt to a wider range of drive configurations without changing the mechanical package. Positioning error remains within ± 1.5 %, helping repeated moves stay within a narrow tolerance band. Kollmorgen’s SIGMAX construction increases magnetic flux to improve usable torque without increasing the motor housing size.

Electrical insulation is supported by a dielectric withstand of 340 VDC and an insulation resistance of 100 megohms. The windings carry a thermal class of Class B, 130 °C, and the motor is intended for continuous operation in ambient conditions from −20 °C to +40 °C. Two internal rotor-stator stacks increase detent torque while keeping the overall length manageable. A smooth shaft supports straightforward coupling to clutches or shaft couplers, and the regular leadwire connection style simplifies wiring at the motor. This shaft style also works well with clamp-type couplings that avoid the added geometry of a keyed connection.
