Our YE4 series three-phase induction motors comply with JB/T  13299-2017, “Technical Specifications for YE4 Series (IP55) Three-Phase Induction Motors (Frame Sizes 80–450)”, and their efficiency ratings conform to IEC 60034 (IE4). This series comprises high-efficiency, energy-saving, and environmentally friendly motors characterized by low operating costs, minimal vibration, low noise, and high reliability, suitable for driving various mechanical equipment without special requirements.

      These motors have a rated voltage of 380 V, a rated frequency of 50 Hz, an IP55 protection rating, and an IC411 cooling method. They employ Class F insulation, with temperature rise at full load evaluated per Class B. They are designed for continuous operation at altitudes up to 1000 m and ambient temperatures ranging from –15 °C to +40 °C. Upon customer request, SIMO can also design and manufacture motors with customized voltages (e.g., 220 V, 400 V, 415 V, 440 V, 660 V), frequencies (e.g., 60 Hz), mounting configurations, or special requirements such as operation above 1000 m altitude—delivering ultra-high-efficiency motors tailored to specific needs.

SIMO Motor is committed to partnering with all customers to actively achieve energy conservation and emission reduction, jointly building a green society.
