Brief Introduction
Manufactured by Xi'an AIMIN Motor Co., Ltd., the YE5 series represents IE5 ultra-premium efficiency three-phase squirrel cage asynchronous motors, fully compliant with national GB standards and international IEC specifications. Developed for global industrial energy-saving upgrades, this high-performance motor range delivers outstanding low-loss operation and long-term stable reliability. The displayed elektromotor 75kw model YE5-280S-4 serves as a flagship 4-pole heavy-duty variant of the YE5 lineup, perfectly engineered for continuous heavy-load industrial applications across Europe, Central Asia and Southeast Asia.
Running on a standard 380V industrial three-phase power supply, this unit features a rated current of 135A, a rated speed of 1490 r/min and an exceptional energy efficiency of 96.7%. Classified under S1 continuous duty cycle, the motor can operate 24/7 under full load without performance degradation or excessive temperature rise. It adopts IP55 protection grade, Class 155 (F-class) insulation and IC411 self-fan cooling structure, paired with C3 large-clearance bearings at both drive and non-drive ends to minimize vibration, noise and thermal expansion risks during long-hour operation. The delta connection design ensures seamless compatibility with most mainstream industrial power grids worldwide, while CE certification grants full access to European and other international markets. As a core high-power drive option, this robust motor is widely matched with large pumps, industrial fans, air compressors, mining conveyors and metallurgical processing equipment.
Through precise finite element electromagnetic optimization, the YE5 series drastically cuts stator copper loss, core iron loss and stray mechanical losses, achieving the top-tier IE5 energy efficiency level. For enterprises with round-the-clock equipment operation, switching to this high-efficiency model yields remarkable electricity savings; the cost premium of the motor can usually be recovered within just two to three years via reduced power bills. Its optimized high power factor also alleviates reactive power waste, improving the overall utilization efficiency of factory power distribution systems and helping factories avoid grid reactive power penalties. This makes our elektromotor 75kw one of the most cost-effective retrofitting choices for old high-power motor energy-saving renovation projects.
Built with high-strength cast iron housing and anti-corrosion surface coating, the YE5 motor withstands harsh working conditions including high humidity, coastal salt fog, chemical volatile gas and dusty open workshops. Every finished motor undergoes comprehensive factory tests covering no-load performance, full-load endurance, insulation resistance, vibration and noise inspection, with a unique production serial number enabling full lifecycle traceability for convenient global after-sales maintenance. Standardized mounting dimensions ensure great interchangeability, allowing equipment manufacturers to replace traditional low-efficiency motors without complicated structural modifications to existing machinery.
From water treatment pump stations and central ventilation systems to mineral processing and building material production lines, AIMIN YE5 IE5 motors provide reliable, eco-friendly power for nearly all heavy-duty industrial scenarios. Adopting this series helps manufacturers strictly comply with global carbon neutrality and energy consumption regulations, while greatly lowering equipment downtime and maintenance expenses throughout the entire service lifespan. With mature manufacturing technology, stable technical parameters and a complete global service network, our elektromotor 75kw and the full YE5 motor range have become a trusted ultra-high-efficiency drive solution for industrial users aiming to balance production stability, energy conservation and long-term economic benefits.
