Product Description:
The E41SMHS-LSS-NS-05 is a hybrid stepper motor manufactured by Kollmorgen for the E Hybrid Stepper Motors series. It supplies precise open-loop positioning torque to automated indexers, packaging carriages, and small gantry axes. This model uses one laminated rotor stack for compact magnetic coupling and has a smooth shaft that mates directly with timing pulleys or couplers. A special winding arrangement increases torque density, while the standard build supports continuous operation at ambient temperatures from -20 °C to +40 °C.
The motor occupies a NEMA 42 frame, providing 4.20-inch square mounting dimensions that match common machinery plates. Its stator uses SIGMAX construction, a Kollmorgen technique that shortens the magnetic path to improve stiffness and reduce energy loss. Field wiring passes through a metric PG11 conduit connector and follows a splash-resistant conduit route to the terminal board, helping protect the leads from coolant and washdown spray. Inside the housing, the phase coils terminate in a four-lead parallel configuration intended for compatible bipolar stepper drives. The motor has a dielectric withstand rating of 340 VDC, which helps prevent insulation breakdown when high-voltage suppression circuits are used. No feedback device is installed, so commanded step pulses control the shaft angle through open-loop operation.
The winding insulation has a thermal endurance rating of Class B at 130 °C. The winding also has an insulation resistance of 100 megohms, providing electrical isolation between the conductors and motor housing. A basic step angle of 1.8 degrees provides 200 discrete positions during each shaft revolution. Cumulative step error remains within ±1.5% of the commanded advance, supporting accurate movement through common mechanical drive ratios. Without encoder or resolver feedback, the controller counts command pulses to track the expected position, while the motor’s low detent torque allows a microstepping drive to produce smoother motion when reduced vibration is required.
