Introduction

The GB/T 21972.2-2023 is a technical specification for variable frequency speed control three-phase asynchronous motors used in lifting and metallurgical applications, specifically designed for axial flow fan cooling. This standard applies to YZP series motors with frame sizes ranging from 100 to 400. The YZP series motors are known for their efficient and reliable performance in power-driven applications. They are widely used in various industries, including metallurgy, mining, and construction, where precise speed control and high torque output are required. With the adoption of variable frequency speed control technology, these motors offer enhanced energy efficiency and reduced noise levels. They are designed to withstand the harsh operating conditions commonly found in heavy-duty applications, ensuring long service life and minimal maintenance requirements. The YZP series motors also feature a compact and robust design, making them suitable for installation in limited space environments. The axial flow fan cooling system effectively dissipates heat generated during operation, ensuring optimal motor performance and preventing overheating issues. In conclusion, the GB/T 21972.2-2023 standard sets the technical requirements for YZP series variable frequency speed control three-phase asynchronous motors, providing a reliable and efficient solution for lifting and metallurgical applications with axial flow fan cooling.
