Engineering Selection Highlights
- NEMA 34 flange → confirms the mechanical mounting interface and motor-frame class for replacement or new-machine design.
- 1.8° step angle → provides 200 full steps per revolution, which defines the base positioning resolution before microstepping.
- 8.6 A parallel rated current → the stepper drive must be selected and configured for the motor’s parallel winding connection and current setting.
- 6.64 Nm holding torque → establishes the static torque capacity; application torque, acceleration, and duty cycle must be evaluated separately.
- Three-stack SIGMAX construction → identifies the motor’s physical length and torque-producing stack configuration.
- Smooth shaft and no encoder feedback → the motor is intended for open-loop stepper control unless an external feedback device is added by the system designer.
- Four parallel-connected leadwires → wiring must match the parallel configuration; incorrect series or parallel connection changes current and torque behavior.

Detailed Product Overview
The Kollmorgen E33NCHA-LNN-NS-00 is a three-stack hybrid stepper motor in the Kollmorgen E Series. Its SIGMAX construction and NEMA 34 flange identify it as a larger-frame stepper motor intended for industrial motion applications requiring relatively high holding torque. The model is documented with a smooth shaft, standard NEMA end bell, Class B insulation, and winding type A.
The motor’s electrical configuration is central to drive selection. It has four leadwires connected in parallel and a rated current of 8.6 A in that configuration. The drive must therefore be capable of supplying and regulating the required phase current, and its current setting must match the parallel winding arrangement. The 1.8° step angle corresponds to 200 full steps per revolution; microstepping, if used, is a function of the selected stepper drive rather than an inherent motor specification.
The E33NCHA-LNN-NS-00 is identified as a stepper motor without encoder feedback. In an open-loop system, position is inferred from the number and frequency of command pulses, so load conditions, acceleration profile, and available torque margin are important design considerations. If an application requires position verification or closed-loop correction, the system designer must add an appropriate external feedback solution; the available references do not identify an integrated encoder for this exact model.
Mechanically, the motor uses a NEMA 34 flange and smooth shaft. The three-stack SIGMAX construction contributes to its 6.64 Nm holding torque and 3.8 kg weight. Mounting and coupling must preserve shaft alignment and avoid side loading; the available references do not provide verified shaft dimensions or bearing-load limits for this exact model.
Applications & System Role
The E33NCHA-LNN-NS-00 is the actuator in an open-loop stepper-motion system. A compatible stepper drive converts pulse and direction commands into phased motor currents, causing the motor to rotate in discrete 1.8° steps.
Its NEMA 34 frame, 6.64 Nm holding torque, and three-stack construction make it a fit for industrial positioning axes that require substantial static torque without integrated feedback. Typical fit scenarios include indexing, positioning, and coordinated motion applications where the drive and mechanical system are designed for open-loop stepper operation.
