YVFE3-355M-4A 250kw Chinese Electric Motor Manufacturers 400v

Brief Introduction

The YVFE3 series variable-frequency three-phase asynchronous motor, manufactured by Xi'an SIMO Motor, represents a leading solution from Chinese electric motor manufacturers for energy-efficient and precise speed-control applications. Designed to meet IE3 premium efficiency standards, it builds on the proven YE3 motor platform with optimized electromagnetic and structural designs, making it ideal for pumps, fans, compressors, conveyors, and other industrial equipment requiring variable speed regulation.

At its core, the YVFE3 series features robust construction, including IP55 protection class, F-class insulation, and IC416 forced cooling via an independent fan. This ensures stable performance across a wide frequency range (25–50Hz constant torque, up to 100Hz constant power), even under low-speed conditions where natural cooling would otherwise be insufficient. The model shown (YVFE3-355M-4A) delivers 250kW at 400V, 422A, and 1490r/min, with a rated torque of 1592N·m, embodying the series' high power density and reliability.

As a trusted name among Chinese electric motor manufacturers, SIMO has engineered the YVFE3 series to address both energy-saving demands and operational flexibility. The motor's parallel vertical fin design enhances heat dissipation, while reinforced mechanical components reduce vibration and extend service life. It supports multiple mounting configurations (IM B3, B35, V1) and customizable voltage/frequency parameters, catering to diverse industrial needs.

Compliant with GB 18613-2020 energy efficiency standards and certified with CE marks, the YVFE3 series meets international quality benchmarks. Whether for new installations or retrofits, it delivers consistent efficiency, low noise, and minimal maintenance, solidifying its position as a preferred choice for industrial automation. In a market where energy conservation and operational precision are paramount, this motor exemplifies the technical prowess of Chinese electric motor manufacturers, offering a cost-effective, high-performance solution for global clients.
