YE4-280M-4 Three-phase Asynchronous 90kw Motor 380V 1500rpm

Brief Introduction

The SIMO YE4 series represents the pinnacle of energy-efficient motor technology from Xi'an SIMO Motor Co., Ltd., designed to meet the most stringent global energy conservation and industrial performance requirements. As a premium line of three-phase asynchronous motors, the YE4 series achieves China Grade 2 energy efficiency, equivalent to the IEC IE4 super premium efficiency standard, setting a new benchmark for sustainability in industrial power applications.

At the core of the YE4 series is exceptional efficiency. The  YE4-280M-4 90kw motor model shown, for example, boasts a remarkable efficiency rating of 96.1%, far exceeding conventional motor standards. This translates to significant energy savings over the motor's lifecycle, directly reducing operational costs and carbon emissions for industrial facilities. The series is engineered for 380V, 50Hz power systems, with a rated speed of 1490 rpm, making it ideal for use with pumps, fans, compressors, conveyors, and general industrial machinery.

Built for reliability in demanding environments, the YE4 series features IP55 protection, which safeguards against dust ingress and low-pressure water jets, ensuring consistent performance in harsh industrial settings. Class F insulation, combined with a temperature rise limit of 155°C, guarantees thermal stability even under continuous S1 duty cycle operation. The IC411 cooling system-totally enclosed fan cooling-effectively dissipates heat, preventing overheating and extending the motor's service life.

Every component is engineered for durability. The motor uses C3 clearance bearings (6317/C3 for the drive end and 6314/C3 for the non-drive end), which are designed to handle higher operating temperatures and reduce noise and vibration. This robust bearing configuration, paired with precision balancing, ensures smooth, quiet operation with minimal maintenance needs. The motor's solid construction, weighing 623kg, reflects its heavy-duty build quality, engineered to withstand the rigors of continuous industrial use.

Compliance with international standards is a hallmark of the YE4 series. Manufactured in accordance with JB/T13299 and certified with the CE mark, these motors meet both Chinese and European regulatory requirements, making them suitable for global markets. The CE certification ensures that the motor adheres to strict safety, health, and environmental protection standards, providing peace of mind for users worldwide.

The YE4 series is not just about efficiency and reliability-it is also about versatility. With a wide range of power ratings and frame sizes available, including the YE4-280M-4 90kw motor shown here, the series can be tailored to meet the specific needs of various industrial applications. Whether used in manufacturing plants, water treatment facilities, mining operations, or HVAC systems, the YE4 motor delivers consistent, high-performance power while reducing energy consumption and operational costs.

In addition to its technical superiority, the YE4 series is backed by SIMO's renowned manufacturing expertise and customer support. With over decades of experience in motor production, Xi'an SIMO Motor Co., Ltd. ensures that every YE4 motor undergoes rigorous quality testing to meet the highest industry standards. The company's dedicated support team, reachable at 400-029-1177, provides comprehensive after-sales service, including installation guidance, maintenance support, and troubleshooting.

In summary, the SIMO YE4 series ultra-high efficiency three-phase asynchronous 90kw motor is a state-of-the-art solution for industrial power needs. With its exceptional energy efficiency, robust construction, reliable performance, and global compliance, it offers a cost-effective, sustainable, and durable power source for a wide range of industrial applications. By choosing the YE4 series, businesses can reduce their environmental footprint, lower operational costs, and ensure long-term productivity.
