Product Description:

Kollmorgen manufactures the E32NCHP-LDN-NK-00 hybrid stepper motor for the E Hybrid Stepper Motors series. The device is a two-phase rotary actuator that converts discrete drive pulses into precise angular motion, allowing packaging lines, small gantries, and laboratory instruments to hold or index loads without a feedback sensor. Its laminated rotor core and dual-stack construction keep the magnetic circuit compact, while the MS-style connector simplifies cable routing in industrial automation systems with limited installation space.

The motor is built on a NEMA 34 frame, giving it a 3.4-inch square mounting face that matches standard gearboxes and brackets. Internally, it produces 200 full steps per revolution, and these increments can be combined with microstepping drives when finer resolution is required. The coil insulation withstands up to 340 VDC, while an insulation resistance of 100 MΩ helps isolate leakage paths during operation with high-voltage bipolar drives. Each command pulse advances the shaft by a 1.8° step angle, allowing travel distance to be calculated directly from the pulse count without additional scaling factors.

The motor has a no-load step accuracy of ±1.5%, which keeps cumulative position error low during extended motion sequences. Electrical terminations use a 4-lead parallel wiring scheme, offering lower phase inductance for higher operating speeds when paired with a compatible drive. Continuous operation is permitted from -20 to +40 °C, allowing use in unconditioned enclosures or lightly ventilated kiosks. The high-speed torque winding generates increased pull-out torque at higher rotational speeds to accommodate inertial loads. A double-ended shaft simplifies the connection of an encoder or mechanical brake without requiring additional adapters. Two rotor stacks increase detent holding capability, while the absence of a shaft seal reduces friction for smoother starts and stops at low speeds.
