Internal Product Review
The E41HLHT-LNK-NS-00 is a Kollmorgen hybrid stepper motor built in a NEMA 42 frame with SIGMAX construction. Performance is especially strong for demanding indexing duty, with 1350 oz-in holding torque and a precise 1.8-degree step angle. Heavy Duty NEMA mounting and a splashproof conduit-board connection make the unit a dependable choice for low-speed, high-torque motion systems.

Product Description:
The E41HLHT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. As a two-phase device, it provides indexed rotary positioning for packaging machines, pick-and-place heads, and other automated axes that require repeatable incremental motion without a feedback sensor. The motor’s SIGMAX construction concentrates magnetic flux to provide higher torque at low speeds, making the unit suitable for applications with frequent starts and stops. A smooth shaft connects directly to clamping couplings or timing pulleys without requiring a keyed interface.
The motor develops 1350 oz-in of static holding torque when each phase is supplied with 5.4 A by a chopper drive. Its low phase inductance of 9.0 mH and phase resistance of 0.61 ohm support responsive current changes during acceleration and deceleration. The NEMA 42 frame encloses a single-stack rotor with an inertia of 0.080 oz-in-s², providing 200 discrete steps per revolution with a step accuracy of ±1.5%. A mechanical step angle of 1.8 degrees provides consistent incremental movement, while four-lead parallel wiring reduces inductive reactance at higher operating speeds. The winding has a thermal resistance of 1.8 °C/W and uses Class B insulation rated for 130 °C. Its insulation system withstands a 340 VDC hipot test and maintains a resistance of 100 megohms to ground.
The motor tolerates up to 400 lb of axial thrust and 140 lb of radial force on the shaft, supporting loads from belt tensioners and vertical lead screws. A splash-resistant connection system routes the terminal board through a 1/2-inch NPS conduit fitting, and four conductors provide a sealed electrical path to the drive. The permitted operating temperature ranges from -20 °C to +40 °C, allowing use in a variety of indoor industrial environments. The aluminum housing weighs 10.9 lb, which limits the added load on the supporting machine frame. Its winding arrangement supports sustained torque during slow indexing sequences, while the housing transfers generated heat to the surrounding air.
