Product Description:

The E41HCT-LNK-NS-01 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. This single-stack motor converts sequences of control pulses into incremental shaft movement, allowing cost-effective open-loop positioning in conveyors, packaging systems, and light machining axes. The motor develops a holding torque of 9.53 N-m, ensuring stable shaft retention when the drive is energized but commanded to remain at a standstill.

Each electrical step advances the rotor by 1.8 degrees, so 200 full steps complete one revolution with a step accuracy of ±1.5%. Because the coils are wired in a four-lead parallel arrangement, the windings draw 5.4 A per phase with a resistance of 0.61 ohms. This arrangement supports high dynamic torque while limiting voltage drop. A phase inductance of 9.0 mH affects the current rise time, balancing responsiveness with drive switching losses. Rotor inertia is 0.565 × 10⁻³ kg·m², and the SIGMAX magnetic design works with the single stack to improve detent linearity. Power and feedback conductors connect through a System MS connector, while the large NEMA 42 frame seats against heavy-duty mounting holes.

The shaft can withstand axial thrusts up to 1780 N and radial side loads up to 623 N, making the motor suitable for belt drives, lead screws, or gearheads mounted directly on the shaft. Continuous operation is supported from −20 °C to +40 °C, and the winding-to-case thermal resistance is 1.8 °C/W, allowing external airflow to reduce temperature rise. Class B insulation is rated for 130 °C and works with an insulation resistance of 100 megohms and a withstand voltage of 340 VDC to protect against dielectric failure. A heavy-duty NEMA flange supports the single-ended shaft, while a shaft seal helps block contaminants. The assembly weighs 4.94 kg, an important consideration when the motor is installed on a moving carriage.
