YX4505-4SZ Three-phase Asynchronous 4 Pole AC Motor 710kW 1490rpm

Brief Introduction

The SIMO YX series 4 pole AC motor represents a premium lineup of high-voltage three-phase asynchronous motors engineered for heavy-duty industrial operation, with the YX4505-4SZ unit as a flagship model for large-power drive scenarios. Developed and manufactured by Xi'an SIMO Motor Co., Ltd., this 4 pole AC motor strictly complies with JB/T 10446 national standards and CE safety specifications, balancing outstanding energy efficiency, stable mechanical performance and long service life to meet the rigorous power demands of mining, metallurgy, water treatment, power plant and heavy machinery industries. Rated at 710kW, 10kV, 50Hz and 1490r/min synchronous rotating speed, the model reaches an energy efficiency rate of 94.8% with Class 2 energy efficiency grade, effectively cutting long-term power consumption for continuous production lines.

In terms of core electrical design, the motor adopts star (Y) stator connection with a rated working current of 48A and a power factor of 0.9 under full load, which minimizes reactive power loss and optimizes matching performance with high-voltage frequency converters and power supply cabinets. Its stator winding applies Class 155 thermal insulation material, enabling stable operation under sustained high-load conditions without premature insulation aging. The motor follows S1 continuous working system, meaning it can run 24 hours nonstop without downtime under standard operating environments, perfectly fitting round-the-clock industrial production processes. For environmental adaptability, the unit supports working temperatures ranging from -15℃ to 40℃ and can run reliably at altitudes up to 1000 meters, avoiding performance attenuation caused by high-altitude thin air or extreme ambient temperatures.

The mechanical and structural configuration of this high-voltage motor is built for robust durability and easy installation and maintenance. It features IP23 protection grade and IC01 natural air cooling mode, paired with IM B35 universal mounting form that combines foot-mounted and flange-mounted structures, offering flexible installation compatibility with pumps, blowers, compressors and various speed reducer equipment. Two heavy-duty bearing sets are equipped separately on the drive end and non-drive end: the drive end uses NU228ECM cylindrical roller bearing to withstand large radial loads generated by heavy transmission equipment, while the non-drive end adopts 6226/C3 deep groove ball bearing to absorb axial offset, greatly reducing bearing wear and vibration during long-term operation. The whole machine weighs 3830kg, with a thickened cast iron frame that enhances structural rigidity to suppress resonance noise under full-speed operation.

Manufacturing quality control runs through every production link of the 4 pole AC motor, ensuring consistent reliability for global industrial clients. Every finished motor undergoes strict no-load, load, insulation resistance and vibration testing before delivery, with unique serial numbers recorded for full lifecycle traceability. The brand SIMO holds mature high-voltage motor R&D and production experience, with a professional after-sales service hotline providing technical consultation, on-site installation guidance and fault troubleshooting for overseas and domestic partners. All products pass CE certification, satisfying cross-border export standards for Southeast Asia, Central Asia, the Middle East and other international markets. Compared with ordinary low-efficiency industrial motors, this series lowers operational costs via high efficiency design and cuts maintenance frequency thanks to wear-resistant bearing configuration, delivering comprehensive economic benefits for enterprise production.

To sum up, SIMO's YX series 4 pole AC motor integrates high power output, superior energy efficiency, strong environmental adaptability and flexible installation advantages, standing as a trusted high-voltage drive solution for large-scale industrial facilities. Whether used to drive water supply pumps in power stations, ventilation fans in metallurgical workshops or conveying equipment in mining plants, this motor maintains stable, low-failure operation over years of continuous use. Supported by standardized production processes and complete international certification systems, Xi'an SIMO Motor can also customize voltage, cooling methods and mounting dimensions of the 4 pole AC motor according to clients' special working condition requirements, creating tailor-made heavy-duty power drive products for global industrial users.
