Product Description:

The E33NCHT-LDN-ND-01 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. This closed-loop-ready component integrates into pick-and-place axes, index tables, and other positioning stations where incremental motion commands must translate directly into repeatable shaft rotation. By combining SIGMAX magnetic construction with a laminated rotor and dual smooth shafts, the motor delivers high detent stiffness and connects easily to encoders or gearheads, providing a compact drive element for step-based control architectures.

The motor uses a NEMA 34 frame, so the front face, mounting holes, and shaft height match standard brackets in conveyor and gantry systems. It develops 6.89 Nm of holding torque because three stator stacks share a low-loss SIGMAX flux path, and the parallel four-lead winding accepts 5.1 A per phase from a bipolar drive. Electrical reactance is governed by a phase inductance of 7.1 mH, while copper losses are limited by a phase resistance of 0.61 ohms. These electrical characteristics influence current rise time and how quickly the 1.8-degree step angle can be driven without overshoot. Each revolution is divided into 200 steps with ±1.5% accuracy, providing encoder-free resolution for moderate-precision axes.

The windings withstand an isolation potential of up to 340 VDC, and the varnish system maintains an insulation resistance of 100 megohms at the Class B insulation limit of 130 °C. An ambient operating range of -20 °C to +40 °C accommodates most cabinet-cooled machinery, while heat generated during operation exits through a 2.0 °C/W thermal path from the stator to the frame. The motor’s 3.45 kg mass acts as a thermal buffer during changes in load. A System MS connector routes the four parallel leads to the drive. The NEMA face flange simplifies mounting in compatible machine assemblies. The winding is tuned for maximum torque at low speed, maintaining output without derating when the shaft turns slowly.
