Internal Product Review
The E41 SMHS-LSS-NS-05 is a Kollmorgen hybrid stepper motor in a NEMA 42 frame with 2-phase operation. A 1.8-degree step angle and ±1.5% step accuracy support precise, repeatable positioning in demanding motion applications. SIGMAX construction reinforces long-term dependability, and 200 steps per revolution stand out as a strong performance advantage.

Product Description:
Kollmorgen manufactures the E41 SMHS-LSS-NS-05 as part of its E Hybrid Stepper Motors series. The motor converts timed current pulses into discrete shaft positions, allowing packaging lines, small gantries, and other automated stations to index loads accurately without feedback devices. By combining laminated rotor stacks with permanent-magnet excitation, it offers consistent holding and incremental motion for open-loop positioning systems.
Its mechanical envelope follows the NEMA 42 frame standard, and electrical entry is provided through a PG13.5 conduit thread that accepts industry-standard glands. Static holding capability is supported by a detent torque of 58 oz-in (0.41 Nm), while dynamic response benefits from a rotor inertia of 0.0800 oz-in-s² and a single laminated rotor stack. The two winding phases are terminated in a four-lead parallel configuration, allowing the coils to operate with low inductance at higher drive currents. Kollmorgen’s SIGMAX construction maximizes flux density through improved lamination geometry, and an insulation system rated to 340 VDC withstands typical bus voltages in microstepping drives. Class B materials support continuous winding temperatures up to 130 °C. The inherent step accuracy remains within ±1.5% per full revolution.
Electrical isolation is reinforced by an insulation resistance of 100 megohms, limiting leakage current in humid environments. The motor operates from -20 °C to +40 °C, making it suitable for unconditioned plant areas within this temperature range. Each electrical transition rotates the shaft by 1.8 degrees, providing 200 steps per revolution for straightforward position calculations in most PLCs. Because the selected model is supplied without feedback, wiring remains minimal while the two-phase excitation pattern supports position control. The laminated rotor and single-stack arrangement also support smoother motion when microstepping drives modulate the phase currents.
