Brief Introduction

The AIMIN YR500 8 pole ac motor, a flagship product from AIMIN Motor, is a high-performance three-phase wound rotor asynchronous motor designed to meet the most demanding industrial challenges. Built on decades of engineering expertise, this motor combines robust construction, exceptional efficiency, and reliable operation to drive critical processes across a wide range of sectors.

At its heart, the YR500 8 pole ac motor delivers a formidable 710 kW of power at a rated speed of 745 rpm on a 50 Hz power supply. This makes it the ideal choice for heavy-duty applications such as large centrifugal fans, water pumps, compressors, and heavy-duty conveyors, where consistent torque and stable performance are non-negotiable. The motor's stator is rated at 10,000 V with a current of 53.2 A, while the rotor operates at 972 V and 460 A, both configured in a Y connection to ensure efficient power transmission and stable operation under variable load conditions.

Durability is engineered into every component. Both stator and rotor windings feature Class 155 (F) insulation, providing superior thermal resistance and extending the motor's operational lifespan. Designed for continuous S1 duty, it boasts an IP23 protection rating, offering reliable defense against dust and water ingress in harsh industrial environments. It can operate reliably in ambient temperatures from -15°C to 40°C and at altitudes up to 1000 meters, ensuring adaptability to diverse operating conditions.

Key design features include premium-grade bearings: NU230ECM at the drive end (D.E.) and 6228/C3 at the non-drive end (N.D.E.), which ensure smooth, low-maintenance operation. The motor employs an IC01 cooling system and IM B3 mounting configuration, enhancing its performance and flexibility for various installation setups. With a mass of 4890 kg, the YR500-8 is built to withstand the rigors of heavy-duty operation, while its compliance with the JB/T10445 standard underscores its adherence to rigorous quality benchmarks.

Backed by AIMIN's global reputation for excellence and a comprehensive service network, the YR500 8 pole ac motor is more than a piece of equipment-it is a strategic investment in operational reliability. Whether powering critical infrastructure or driving production lines, this motor delivers the performance, efficiency, and peace of mind that industrial operations demand.
