Internal Product Review
The E41RCHT-LNK-NS-00 is a Kollmorgen hybrid stepper motor with 1350 oz-in holding torque and a 1.8 degree step angle. A System MS connector and 4 lead parallel configuration make integration especially clean for motion-control assemblies. The max-torque-at-low-speed winding and 5.4 A per-phase rating make this model a strong performer for demanding indexing duty.

Product Description:
The E41RCHT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. It converts discrete drive pulses into controlled angular motion for indexing tables, carton sealers, and other industrial automation axes that do not require closed-loop feedback. SIGMAX construction concentrates magnetic flux in the rotor, allowing higher torque density within the same envelope. Electrical power enters the stator through a System MS connector that carries the four parallel phase leads.
With a frame size of NEMA 42, the motor aligns with common mounting layouts used across heavy-duty machinery. Its static holding capability reaches 1350 oz-in, so fixtures stay locked when drive current is present. Each winding draws 5.4 A at standstill; that current across a per-phase resistance of 0.61 ohms establishes the required magnetic field while limiting copper loss. Dynamic behavior is influenced by an inductance of 9.0 mH, which affects the electrical time constant and the usable pulse rate. Class B insulation rated to 130 °C and a dielectric withstand rating of 340 VDC protect the stator against thermal and voltage stress. The insulation resistance is 100 megohms, limiting leakage current through the winding insulation. The rotor inertia of 0.080 oz-in-s² helps minimize settling time during rapid indexing.
Each full step advances the shaft by 1.8 degrees, yielding 200 discrete positions per revolution with a step accuracy of ±1.5%. The smooth shaft can withstand axial forces up to 400 lb and radial forces up to 140 lb, enabling direct belt or pulley attachment. Despite its torque capability, the motor weighs only 10.9 lb, easing installation on moving carriages. Its thermal resistance is 1.8 °C/W, indicating the relationship between power loss and winding temperature rise. Continuous operation is supported throughout an ambient temperature range of -20 °C to +40 °C. A single magnetic stack limits the motor’s overall length, while the maximum-torque-at-low-speed winding provides high stall torque for indexing cycles.
