YE4‑112M‑4 Three-phase Asynchronous Motor 4kw 380v

Brief Introduction

The YE4 series three‑phase asynchronous motors developed and manufactured by Xi'an SIMO Motor Co., Ltd. represent top‑tier super‑high‑efficiency drive solutions for modern industrial applications, engineered to meet global energy‑saving requirements and strict international efficiency standards. As a premium energy‑saving motor lineup, YE4 motors deliver outstanding efficiency performance, with the YE4‑112M‑4 motor 4kw 380v achieving an efficiency rate up to 91.1%, effectively cutting power consumption and lowering operational costs for long‑term industrial production.

All YE4 series motors are built with robust structural design and premium‑grade components. They adopt Class 155 thermal insulation, IC411 self‑ventilation cooling system and IP55 protection grade, offering excellent dustproof, waterproof and moisture‑proof capabilities. Under rated 380V, 50Hz three‑phase power supply, YE4‑112M‑4 motor 4kw 380v runs stably at standard rotational speeds (e.g., 1450 r/min for 4‑pole types), with stable power factor and low vibration, low noise features. Equipped with high‑precision bearings such as 6206‑2Z/C3, these motors ensure smooth rotation, long service life and minimal maintenance workload.

Strictly compliant with JB/T 13299 national standards and CE certification, SIMO YE4 series motors support IM B3 mounting form and delta connection, adapting to diverse installation scenarios. They cover multiple power specifications, perfectly matching pumps, fans, compressors, conveyors, machine tools and other general‑purpose industrial equipment. Compared with ordinary low‑efficiency motors, YE4 series greatly improves energy utilization efficiency, helping enterprises achieve carbon neutrality goals and reduce operating expenses.

SIMO YE4 motors are manufactured with rigorous quality control throughout production, from raw material screening to finished‑motor testing. Every unit undergoes strict performance inspections before delivery to guarantee stable output and reliable continuous operation. With compact structure, high power density and strong adaptability, YE4 series is widely exported to global markets, favored by industrial users for its high efficiency, durability and cost‑effectiveness.

For global buyers seeking energy‑efficient industrial drive motors, SIMO YE4 series (YE4‑112M‑4 motor 4kw 380v as model) super‑high‑efficiency asynchronous motors are your ideal choice, combining advanced technology, stable quality and comprehensive after‑sales service.
