This standard specifies the type, basic parameters and dimensions, technical requirements, test methods and inspection rules of YZC series (IP44) low-vibration and low-noise three-phase asynchronous motors, as well as packaging, marking and warranty period requirements. This standard applies to YZC series (IP44) three-phase asynchronous motors (frame size 80 to 160). Various series of motors derived from this series of motors can also be implemented with reference.
