YE4-225S-4 Three-phase Asynchronous Elektromotor 37 Kw 380V

Brief Introduction

The SIMO YE4-225S-4 is a premium three-phase asynchronous elektromotor 37 kw, engineered by Xi'an SIMO Motor Co., Ltd. to deliver exceptional energy efficiency, reliable performance, and long service life for demanding industrial applications. As an IE4 ultra-high-efficiency motor, it sets a new benchmark for energy conservation, making it an ideal choice for businesses seeking to reduce operational costs and meet global carbon-neutrality goals.

Designed with a 4-pole configuration, this elektromotor 37 kw delivers a rated power of 37kW (50HP) at 380V, 50Hz, with a rated current of 69.5A and a power factor (cosφ) of 0.85. Boasting an outstanding efficiency of 95.2%, it far exceeds national and international energy efficiency standards, significantly cutting down power consumption during continuous operation. The motor adopts a delta (△) connection method, ensuring stable electrical performance and compatibility with standard industrial power grids.

Built for rugged industrial environments, the YE4-225S-4 features an IP55 protection degree, providing robust resistance to dust, moisture, and water splashes, making it suitable for harsh operating conditions such as manufacturing plants, mining sites, and outdoor installations. It is equipped with F-class insulation (thermal class F), offering excellent heat resistance and electrical insulation performance, which extends the motor's service life and ensures reliable operation even under heavy loads. The IC411 self-ventilated cooling system efficiently dissipates heat, maintaining optimal operating temperatures during continuous S1 duty cycles.

The motor is mounted in the B3 foot-mounted configuration, a universal design compatible with a wide range of industrial machinery, including pumps, fans, compressors, conveyors, and machine tools. It is fitted with high-performance 6313/C3 deep groove ball bearings, which reduce friction, lower noise levels, and ensure smooth, low-vibration operation. With a net weight of 299kg, the motor balances structural rigidity and ease of installation, while its CE certification guarantees compliance with European Union safety, health, and environmental protection standards.

Backed by Xi'an SIMO Motor's decades of expertise in motor manufacturing, the YE4 series motor undergoes rigorous quality testing and strict quality control throughout the production process. It is an ideal solution for industrial users looking to upgrade their equipment for higher energy efficiency, lower maintenance costs, and enhanced operational reliability. Whether for new installations or retrofitting existing systems, the SIMO YE4-225S-4 elektromotor 37 kw delivers outstanding performance and long-term value.
