E34HRHT-LDS-SS by Kollmorgen

The E34HRHT-LDS-SS from Kollmorgen is a high-performance member of the E Hybrid Stepper Motors series, engineered for demanding industrial applications. This hybrid step motor features a robust NEMA 34 frame size and a precision frame dimension of approximately 3.38 inches in diameter, ensuring compatibility with standard mounting systems. Designed with Pacific Scientific SIGMAX technology, the motor delivers exceptional magnetic performance and torque density. The unit’s mounting configuration employs heavy-duty NEMA mounting hardware for secure installation in harsh environments. With a motor type optimized for cyclic and intermittent operation, it meets the rigorous reliability standards of modern automation.

Featuring a typical 2-phase configuration, the E34HRHT-LDS-SS provides smooth motion control with a step angle of 1.8° for precise microstepping. Its rated current of approximately 4.2 A per phase supports sustained high-torque output without overheating. The design leverages high-quality materials and precision winding techniques to maintain consistent inductance and current distribution across phases. With high torque performance, the motor achieves superior holding torque and rapid acceleration profiles. Its robust construction mitigates vibration and resonance, enabling stable operation at both low and high speeds.

Operationally, the E34HRHT-LDS-SS excels in applications requiring exact positioning and robust load handling. The advanced SIGMAX design increases torque density, allowing for higher torque without enlarging the frame size—a critical advantage in space-constrained machinery. Thermal management is enhanced by the heavy-duty frame and precision winding, reducing temperature rise during continuous duty cycles. Maintenance intervals are extended thanks to durable bearings and sealed construction that resist dust and particulate ingress. Integration with standard stepper drives and controllers is straightforward, facilitating quick commissioning and reducing downtime.

This motor seamlessly integrates into CNC machining centers, robotics, medical devices, packaging equipment, and other automated systems where reliability and precision are paramount. Its heavy-duty mounting configuration supports direct coupling with lead screws, belt drives, and gearheads, simplifying mechanical design. Engineers benefit from the motor’s consistent performance characteristics, which enable predictable system behavior and streamlined motion profiles. The E34HRHT-LDS-SS sets a new standard for hybrid stepper motors in industrial automation, delivering both power and accuracy in a compact package.
