Brief Introduction

The SIMO YVFE4-280S-4A motor 7 5 kw 1500 rpm is a high-performance variable frequency speed-regulating three-phase asynchronous motor manufactured by Xi'an SIMO Motor Co., Ltd. (SIMO), a leading enterprise in China's high-voltage motor manufacturing industry. As a core model of the YVFE4 series, this motor is engineered upon the advanced YE4 ultra-high-efficiency motor platform, adhering to the international IE4 efficiency standard and Chinese national standards such as GB 18613, making it a benchmark for energy-saving power transmission equipment in modern industrial settings.

Core Technical Specifications & Design Advantages

With a rated power of 75 kW, rated voltage of 380 V, and rated current of 136 A, the YVFE4-280S-4A motor 7 5 kw 1500 rpm delivers stable output at a rated speed of 1490 r/min, perfectly matching the speed requirements of medium-power industrial equipment. Its mechanical design features premium components: the drive-end (D.E.) and non-drive-end (N.D.E.) bearings adopt the 6314/C3 specification, ensuring low friction and high durability under continuous operation. The motor employs an IP55 protection grade and IC416 cooling method, providing robust resistance to dust, water splashes, and high-temperature environments, while maintaining efficient heat dissipation to prevent overheating during long-term operation.

Equipped with class F insulation (thermal class 155) and an IM B3 foot-mounted installation design, it complies with IEC international standards, ensuring broad compatibility with industrial automation systems. The motor supports a wide speed regulation range of 50–100 Hz, enabling flexible speed control to match diverse load demands-whether constant torque operation below 50 Hz or constant power operation above 50 Hz, it maintains stable performance with minimal torque ripple.

Distinguishing Features vs. Conventional & Competitor Motors

What sets the YVFE4 series apart lies in its targeted optimization for variable frequency drive (VFD) systems, a critical distinction from standard asynchronous motors and basic variable frequency motors (YVFE2/YVFE3 series). Unlike conventional motors that suffer from poor compatibility with VFDs, leading to insulation damage and high vibration, the YVFE4-280S-4A features an optimized electromagnetic design that minimizes harmonic interference from VFDs. This design reduces current harmonic losses by 15–20% compared to standard motors, extending the motor's service life and reducing maintenance costs.

Furthermore, the motor integrates advanced vibration reduction technology, limiting vibration amplitude to ≤2.3 mm/s-far lower than the industry average of 3.5 mm/s for ordinary VFD motors. This precision ensures stable operation in precision equipment scenarios, such as high-precision pumps and fans, where vibration stability is critical. In terms of energy efficiency, it achieves a 3–5% higher efficiency than the YVFE3 series and 8–10% higher than ordinary YE3 high-efficiency motors, translating to significant energy savings in continuous industrial operation.

Application Versatility & Industrial Value

The YVFE4-280S-4A excels in a wide range of industrial applications, including water supply systems, air handling units, compressors, and conveyor systems. Its S1 continuous duty rating ensures reliable operation 24/7, making it ideal for energy-intensive industries such as manufacturing, water treatment, and HVAC. For global markets, it supports 50/60 Hz dual-frequency operation, facilitating easy adaptation to international power grids-a key advantage for export-oriented projects.

Backed by SIMO's rigorous quality control and technical support, including a 1-year warranty and professional after-sales service, this motor delivers a balance of high efficiency, reliability, and adaptability. As a core product of SIMO's YVFE4 series, the YVFE4-280S-4A motor 7 5 kw 1500 rpm not only meets the growing demand for energy-saving industrial equipment but also sets a new standard for variable frequency motor performance in the global market.
