E33NRHT-LNN-NS-00
by Kollmorgen
The Kollmorgen E33NRHT-LNN-NS-00 from the E Hybrid Stepper Motors series is a high-performance stepper motor delivering a holding torque of 6.89 Nm and operating at a rated current of 5.1 A per phase. Designed for industrial and automation applications, it ensures precise motion control, consistent positioning accuracy, and reliable torque output for robotics, packaging machines, and medical devices where stability and repeatability are critical.
This stepper motor features a phase resistance of 0.61 ohms and a phase inductance of 7.1 mH, providing optimized current flow and fast dynamic response. Its detent torque of 0.45 Nm enhances stability at standstill, while the rotor inertia of 0.177 kg·m² × 10⁻³ delivers efficient acceleration and deceleration for varying load profiles. Thermal management is addressed via a built-in heat sink and a thermal resistance of 2.0°C/W, ensuring effective dissipation of heat under continuous operation.
Equipped with advanced DSP-based signal processing and 4 output channels, the E33NRHT-LNN-NS-00 supports an input voltage range of 220–240 VAC and a frequency response from 20 Hz to 20,000 Hz for versatile drive compatibility. The shaft loading capacity of 156 N radial and 801 N axial (upgradable to 427 N axial) provides robustness under high mechanical stresses. Weighing 3.45 kg, this motor offers durability and long service life. Its precision winding configuration, thermal design, and mechanical strength together meet stringent industrial standards, delivering enhanced efficiency, reduced maintenance, and exceptional reliability in demanding automation environments.
