Product Description:
The E41HLFB-LSS-NS-02 hybrid stepper motor is produced by Kollmorgen and belongs to the E Hybrid Stepper Motors series. As a NEMA-frame motor that advances in precise increments, it is used in industrial automation to index tooling, position slides, or meter product flow where open-loop motion is suitable. The motor is built without feedback devices, allowing the connected drive to control movement by counting command pulses. SIGMAX construction concentrates magnetic flux to provide higher torque per unit of volume, while the single magnetic stack helps minimize the motor’s overall length.
With a NEMA 42 frame, the motor occupies a 4.2-inch square envelope and mates with a 3.000-inch bolt circle and a 2.186-inch pilot. Each electrical pulse turns the rotor by 1.8 degrees, resulting in 200 commanded steps per revolution. Step accuracy remains within ± 1.5% of the commanded position. The rotor and stator geometry supports unipolar and bipolar phase operation, allowing the motor to work with a broad range of compatible power stages. A smooth shaft accepts clamping couplings without requiring a keyed connection. Heavy-duty NEMA mounting helps maintain alignment, while a splash-proof conduit entry protects the wiring path from incidental moisture. The coil topology can be reconfigured through the external wiring without disassembling the motor housing.
The winding uses a Class B insulation system rated for 130 °C to withstand elevated temperatures during sustained load cycles. The permitted ambient temperature range is −20 °C to +40 °C; operation outside this range may reduce available torque or service life. The coil insulation has a resistance of 100 megohms at a 500 V test voltage. It also withstands a working potential of 340 VDC. The motor has eight-lead connections that provide access to the individual coil sections for the selected drive arrangement. These discrete leads exit through a 1/2 NPSC conduit thread that accepts a 1/2-inch NPS pipe-thread connector. This splash-proof cable path routes the conductors to the internal terminal board while limiting exposure at the housing entry point.
