YE4-90~355 series (IP55) high-efficiency three-phase asynchronous motors are the latest fully enclosed self-fan-cooled squirrel-cage high-efficiency three-phase asynchronous motors developed by our company. The efficiency index of this series of motors reaches the Level 2 energy efficiency level in China's GB18613-2020 "Energy Efficiency Limits and Energy Efficiency Levels of Small and Medium-sized Three-Phase Asynchronous Motors". YE4-90~355 series high-efficiency three-phase asynchronous motors have high efficiency and various performance indicators have reached the international advanced level. This motor is used to drive fans, pumps and other long-term running loads, which can save considerable electrical energy and help protect the environment.
The installation size and power level of YE4-90~355 series (IP55) high-efficiency three-phase asynchronous motors comply with the International Electrotechnical Commission IEC72-1 standard. Motors with center height H160 and above are equipped with non-stop oil filling and draining devices, and are reserved for installation heat. There is space for sensitive resistors and moisture-proof heating tapes for user convenience. The stator of the motor adopts F-class insulation, but the temperature rise is assessed at 80K. The motor has a large temperature rise margin and a long service life. The rotor adopts cast aluminum technology and has high operational reliability.
Power range of this series of motors: 0.75~315KW;
Frame size center height: H90~355
