Internal Product Review
The E42HLHT-LNK-NS-02 is a Kollmorgen hybrid stepper motor with a NEMA 42 frame and 18.0 N·m holding torque. A 1.8-degree step angle and ±1.5% step accuracy support precise low-speed positioning in demanding motion systems. Heavy Duty NEMA mounting adds installation confidence, and the max torque at low speed winding makes this motor a strong choice for high-load indexing applications.

Product Description:
The E42HLHT-LNK-NS-02 hybrid stepper motor is produced by Kollmorgen within the E Hybrid Stepper Motors series. As a positioning element for indexing tables, pick-and-place actuators, and similar motion systems, it converts pulse trains into incremental rotation. SIGMAX laminated construction supports high flux density, while the heavy-duty NEMA mounting face supports installation in compatible legacy frames. A splashproof conduit entry routes the leads to a terminal board through a 1/2 in NPS pipe thread. The stator is wound for maximum torque at low speed and configured as a four-lead parallel circuit across the two magnet stacks. The output shaft has a smooth finish for use with press-fit couplings.
The motor occupies a NEMA 42 frame and develops a holding torque of 18.0 N·m, giving it the capacity to maintain load position without an external brake. Each phase operates at 7.9 A and has a coil resistance of 0.41 ohm. Its phase inductance is 7.8 mH, which influences the current rise time during microstepping. A fundamental step angle of 1.8 degrees sets the electrical commutation interval. Step accuracy is ±1.5%, supporting repeatable positioning throughout the motor’s rotation. The rotor inertia is 0.16 oz-in-s², which affects the acceleration and deceleration available for a connected load. High-resolution stepper drives can regulate phase current to produce controlled motion across the operating speed range.
One revolution is subdivided into 200 discrete steps, so direct coupling to lead screws or timing pulleys produces predictable linear advances. The motor operates from -20 °C to +40 °C and has a thermal resistance of 1.3 °C/W. Its Class B insulation system permits a winding temperature of up to 130 °C when the motor is operated within its allowable load conditions. The insulation resistance is 100 megohms when measured at 340 VDC, providing resistance to common industrial voltage transients. The bearings can withstand radial loads up to 623 N and axial forces up to 1,780 N under appropriate mounting and operating conditions. With a mass of 8.26 kg, the motor adds a substantial static and dynamic load when installed on a moving axis.
