Introduction

GB/T 21972.3-2023 "Technical specification for variable frequency speed control three-phase asynchronous motors for lifting and metallurgical applications - Part 3: YZP series variable frequency speed control three-phase asynchronous motors for lifting and metallurgical applications (centrifugal fan cooling) (frame size 100-400)" is a national standard in China that specifies the technical requirements for YZP series variable frequency speed control three-phase asynchronous motors used in lifting and metallurgical applications, with centrifugal fan cooling. This standard covers motors with frame sizes ranging from 100 to 400, providing guidance on their design, performance, and testing. The YZP series motors are specifically designed for applications that require variable frequency speed control, such as cranes and metallurgical equipment. They are equipped with centrifugal fan cooling systems to ensure efficient heat dissipation and reliable operation. The standard defines the technical parameters, including rated power, rated voltage, rated frequency, and operating conditions, for YZP series motors. It also specifies the performance requirements, such as the efficiency, temperature rise, and noise level, that the motors should meet. By adhering to the requirements of GB/T 21972.3-2023, manufacturers can ensure the quality and reliability of YZP series variable frequency speed control three-phase asynchronous motors for lifting and metallurgical applications. This standard serves as a valuable reference for both manufacturers and users in the industry.
