SEW DRN71M4/DH Product Description

The SEW DRN71M4/DH is an IE3 high-efficiency three-phase asynchronous motor built on SEW modular drive platform for continuous industrial operation. This three-phase asynchronous motor features 0.37kW rated power and 4-pole design, delivering stable torque output for material handling, conveyor systems and automated machinery. This three-phase asynchronous motor adopts cast aluminium housing with lightweight structure and good heat dissipation performance to keep temperature stable during long-time running. This three-phase asynchronous motor complies with IEC standard and IE3 energy efficiency grade, helping factories cut long-term power consumption and meet global energy-saving regulations.

This SEW motor is equipped with reliable motor winding assembly that is manufactured under strict insulation standards to resist voltage fluctuation and thermal aging. The motor winding assembly uses Class F insulation material, which can withstand high operating temperature and extend the whole motor service cycle. The motor winding assembly supports both star and delta wiring modes, adapting to 230V/400V power supply for flexible on-site electrical configuration. The motor winding assembly passes strict factory testing to reduce risk of short circuit and insulation breakdown under heavy-duty working conditions.

The model supports versatile installation types and optional brake or encoder add-ons to satisfy closed-loop speed control demands. Robust industrial drive control matches this motor perfectly, realizing stable speed regulation and overload protection in automated production lines. Precise industrial drive control monitors motor current and temperature in real time to trigger protective action once abnormal operating status occurs. Flexible industrial drive control works well with SEW frequency converters, supporting speed adjustment for conveying, packaging and processing equipment. Stable industrial drive control reduces mechanical impact during start and stop, lowering wear on transmission components and maintenance workload.

The SEW DRN71M4/DH comes with IP54 standard protection grade, effectively preventing dust and splashing water from entering the motor interior. Its squirrel-cage rotor structure brings low vibration and low noise operation, suitable for continuous S1 duty cycle. Multiple optional accessories are available including thermal sensors, manual brake release and different shaft or flange configurations. The modular design allows quick combination with SEW standard gear reducers to form integrated gearmotor units, saving installation space and simplifying mechanical layout. Widely used in logistics conveyors, packaging machines, small processing equipment and general automation systems, this SEW three-phase asynchronous motor offers dependable performance for global industrial drive applications.
