Scope

Scope: This standard specifies the types, basic parameters and dimensions, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation, storage, and warranty period requirements for three-phase asynchronous fan motors used in wind power systems of the YFF and YFD series, including cabin ventilation fan motors and oil pump cooling fan motors, with base numbers ranging from 100 to 132 (hereinafter referred to as "motors"). Main technical content: - These motors are suitable for use in wind power systems under alternating humid-heat, high-low temperature, and high-corrosive environments, and can meet the C5 corrosion protection grade in high-corrosive marine environments. - These motors feature excellent low-temperature start-up performance and strong overload capacity. They can start and operate normally in high-altitude (4000 meters) and low-temperature (-30°C) environments. The motors meet the requirements for use in high-temperature environments, with a maximum allowable ambient temperature of +55°C. Through optimized electromagnetic design and improved product structure, the comprehensive performance of these motors has reached advanced domestic standards. - These motors meet the special power supply characteristics of wind power systems. Wind power auxiliary motors typically use 400V/690V inverter-rectifier waveform power supplies with high harmonic content and high voltage rise rate (du/dt), which places high demands on the insulation strength of the motor windings. The motor windings are made of high-strength, high-tensile, high-temperature-resistant, and corona-resistant enameled copper wires, and undergo special insulation processing, ensuring safe and reliable performance with a 5-year maintenance-free period. - YFF and YFD series fan motors are widely used in the wind power industry, but there are no corresponding dedicated standards in China or abroad. The formulation of this standard will guide and standa
