Brief Introduction

The AIMIN YVF225S-4A W is a high-performance VVVF three-phase asynchronous motor, built to deliver reliable variable-speed control for demanding industrial environments. As a 3 phase 4 pole motor, it operates with a rated power of 37 kW, a 380V rated voltage, and a 70.5A rated current, achieving a base speed of 1480 rpm at 50Hz. Designed for variable-frequency drives, it supports a wide operating range of 3–50Hz, with extended performance up to 70Hz, making it highly adaptable to dynamic load requirements. The motor is constructed with IP55 ingress protection, Class F insulation (155°C thermal class), and IC416 cooling, ensuring durability in dusty, humid, or temperature-fluctuating conditions. It complies with JB/T7118 standards, features B3 (foot-mounted) installation, and has a total weight of 290 kg, with bearings 6313/C3 for enhanced operational stability.

Beyond core specifications, this 3 phase 4 pole motor offers distinct advantages tailored to variable-speed industrial needs. Its variable-frequency design allows precise speed regulation, reducing energy consumption by matching motor output to actual load requirements-ideal for pumps, fans, and conveyor systems where speed adjustment directly impacts operational efficiency. The robust construction, including high-quality C3 clearance bearings and IP55 protection, minimizes maintenance needs and extends service life, even in continuous S1 duty cycles. The motor's 37 kW power rating and 235.5 N·m rated torque deliver consistent performance across the speed range, while compliance with EN efficiency standards ensures it meets global sustainability and cost-saving goals. Additionally, its wide frequency tolerance (3–70Hz) enables compatibility with diverse drive systems, making it suitable for retrofitting into existing setups or integrating into new projects.

Designed for versatility, this 3 phase 4 pole motor excels in applications where speed control and reliability are critical. It is widely used in water treatment plants, HVAC systems, material handling lines, and manufacturing processes, where variable speed regulation optimizes process control and reduces operational costs. Whether powering centrifugal pumps in water distribution systems or variable-speed fans in ventilation units, the AIMIN YVF225S-4A W combines efficiency, durability, and adaptability to meet the evolving needs of modern industries. Backed by AIMIN's decades of engineering expertise, this motor is a trusted solution for businesses seeking a high-performance variable-frequency drive motor that balances power, efficiency, and long-term reliability.
