Scope
Scope: This standard specifies the types, basic parameters and dimensions, technical requirements, inspection rules, marking, packaging, and warranty period requirements of YE3 series ultra-high efficiency three-phase asynchronous motors. This standard applies to YE3 series ultra-high efficiency three-phase asynchronous motors (frame sizes 80~355) (hereinafter referred to as "motors"). Main technical content: This standard is based on and improved upon GB/T 28575-2012 "Technical Conditions for YE3 Series High-Efficiency Three-Phase Asynchronous Motors (Frame Sizes 80-355)". This standard takes into account the actual situation of market customers, and increases the shell protection of the motor and the rated power of the motor to meet different customer requirements. Under each frame size, the efficiency, power factor, maximum torque multiplier, minimum torque multiplier, and starting current multiplier are given for the increased power. The main differences between this standard and GB/T 28575-2012 "Technical Conditions for YE3 Series High-Efficiency Three-Phase Asynchronous Motors (Frame Sizes 80-355)" are as follows: - The shell protection level of the motor is increased to IP55; - The rated frequency of the motor is increased to 50Hz.
