Product Description:

The E32NRFP-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen as part of the E Hybrid Stepper Motors series. This two-stack unit is intended for open-loop or closed-loop positioning in automated machinery, where pulse commands are converted into incremental shaft movement for indexers, small conveyors, and tooling fixtures. Standard NEMA mounting dimensions support installation on equipment that uses the same bolt circle and pilot diameter. The hybrid rotor design also supports precise low-speed motion in applications that need repeatable starts, stops, and holding behavior. That makes the motor suitable for machines that need controlled incremental motion without the added complexity of a servo package.

The motor uses a NEMA 34 frame, giving it a square 3.4-inch face and enough rotor volume for moderate torque output. Each full step moves the shaft by 1.8 degrees, which creates 200 discrete positions per revolution without microstepping. This step resolution is useful for indexing tasks that rely on direct pulse input from a compatible drive. The windings are insulated to Class B, 130 °C, and the insulation system has 100 Megohms of resistance when measured at room temperature. A dielectric withstand rating of 340 V DC is provided between the windings and frame, while the two-stack construction increases detent torque for loads with higher inertia. The smooth shaft has no keyway, which simplifies coupling alignment and reduces local stress at the shaft surface.

The motor is rated for operation from -20 °C to +40 °C, which supports use in many unconditioned industrial spaces. A regular lead-wire arrangement uses 8 lead connections instead of a fixed connector, allowing series or parallel winding configurations to match the drive and current requirements. Positional repeatability is supported by a step accuracy of ± 1.5 %, which is suitable for many indexing and transfer applications. The internal magnetic path uses SIGMAX construction, which helps the motor maintain torque as pulse rates increase. Lead wires can also be routed through terminal blocks or drive terminals where a molded plug is not preferred.
