YE3-250M -2 55kw Electric Motor 380V 3000rpm ip55

Brief Introduction

The 55kW electric motor (model YE3-250M-2) is a premium-efficiency three-phase asynchronous motor manufactured by Xi'an SIMO Motor Co., Ltd., engineered to meet the highest industrial performance and reliability standards. Built in compliance with GB/T 28575 and IE3 efficiency specifications, this motor delivers exceptional energy efficiency and consistent power output for demanding continuous-duty applications.

At the core of its performance, the 55kW electric motor operates at 380V/50Hz, with a rated speed of 2970 r/min and a power factor (cosφ) of 0.90, ensuring optimal power utilization. Boasting a high efficiency rating of 94.3%, it significantly reduces energy consumption and operational costs over its service life, aligning with global energy-saving initiatives. The motor is equipped with Class F insulation and a temperature rise limit of 155°C, providing robust thermal stability even under prolonged operation.

For durability in harsh environments, the motor features an IP55 protection rating, safeguarding against dust ingress and water splashes, while its IC411 cooling system maintains consistent operating temperatures. The use of 6314/C3 bearings on both the drive and non-drive ends minimizes vibration and noise, extending service life and reducing maintenance needs. With a total weight of 362kg, its cast-iron construction ensures mechanical rigidity, making it suitable for heavy-duty industrial use.

Versatile in application, this 55kW electric motor excels in powering pumps, fans, compressors, conveyors, and other general industrial machinery across sectors like water treatment, HVAC, mining, metallurgy, and manufacturing. Its S1 continuous duty rating allows non-stop operation, while the Y-type connection ensures flexible integration into various power systems. Certified with CE compliance, it meets international safety and quality standards, making it suitable for both domestic and export markets.
