Brief Introduction

An industrial 1500 rpm cooler motor plays a critical role in heavy-duty cooling, ventilation, and power-transmission systems that require high energy efficiency and precise speed control. Manufactured by Xi'an AIMIN Motor Co., Ltd., the YVF355L1-4A W series variable frequency three-phase asynchronous motor is engineered to meet the demanding operational requirements of modern industrial machinery. Featuring a robust cast-iron frame and precision electromagnetic design, this motor operates at a rated voltage of 380V, a rated current of 497A, and a base power output of 250kW with a nominal speed of 1490 r/min. Built in compliance with the JB/T7118 standard, it offers an exceptional balance of mechanical strength, high starting torque, and continuous operational reliability under variable thermal and load conditions.

Equipped with advanced variable voltage and variable frequency (VVVF) capabilities, this drive unit enables seamless speed regulation across a wide 5Hz to 100Hz spectrum. Whether integrated into large industrial blowers, water pumps, heavy-duty compressors, or mining systems, this high-capacity 1500 rpm cooler motor delivers dynamic acceleration and smooth performance under fluctuating loads. The optimized magnetic circuit design significantly reduces energy consumption, acoustic noise, and temperature rise during continuous duty cycles. When paired with variable frequency drives (VFD), operators achieve superior process automation, precise flow control, and substantial reduction in long-term power consumption.

Designed to withstand harsh operating environments, the motor features an IP55 ingress protection rating that shields internal windings and core components from dust, moisture, and chemical contaminants. Its Class 155 (F) insulation system provides extraordinary thermal margins and dielectric strength, effectively resisting the voltage spikes typical of modern inverter switching. Additionally, the unit incorporates premium 6322/C3 deep groove ball bearings on both the drive end (D.E.) and non-drive end (N.D.E.). These high-load bearings minimize friction and mechanical vibration, extending service intervals and ensuring overall mechanical stability in heavy-industry applications such as power generation, metallurgy, and large HVAC installations.

Combining rugged mechanical construction, advanced VVVF performance, and strict quality engineering, AIMIN offers a comprehensive solution for demanding cooling and drive systems. It serves as an optimal choice for facilities aiming to upgrade their industrial infrastructure, maximize operational uptime, and achieve lower lifecycle maintenance costs. Modernize your industrial production line with high reliability and control efficiency using this powerful 1500 rpm cooler motor.
