Product Description:
The E42HCHT-LNK-NS-01 hybrid stepper motor is produced by Kollmorgen for the E Hybrid Stepper Motors series. It indexes and holds machine axes in packaging, semiconductor, and general automation equipment where repeatable mid-torque performance is required. The motor converts pulse and direction commands into incremental rotation, eliminating feedback hardware in applications that tolerate open-loop positioning but still demand high holding torque.
SIGMAX construction inside a NEMA 42 frame and a heavy-duty NEMA mounting flange provide mechanical stiffness, while a smooth shaft simplifies coupling. With a step angle of 1.8 degrees, the rotor advances through 200 discrete positions per revolution and maintains ±1.5% accuracy. Two magnetic stacks and the max-torque-at-low-speed winding raise the holding torque to 18.0 N·m. The rotor inertia is 1.13 × 10⁻³ kg·m², which balances rapid acceleration with position stability. Electrical excitation is delivered through four-lead parallel connections that terminate in a System MS connector; each phase draws 7.9 A with a resistance of 0.41 ohms and an inductance of 7.8 mH. The insulation system is rated for 340 V DC, provides 100 megohms of insulation resistance, and uses Class B materials that tolerate temperatures up to 130 °C. Its thermal resistance is 1.3 °C/W, allowing stator heat to move to the mounting surface.
The motor supports axial shaft forces up to 1780 N and radial loads up to 623 N, permitting the use of belt drives or lead screws without causing premature bearing wear. It operates from -20 °C to +40 °C, while the Class B insulation helps keep the winding within its temperature limit during sustained operation. The motor has an overall mass of 8.26 kg, allowing installation on moving axes without adding excessive weight to the machine assembly.
