Product Description

YPKK series high-voltage variable frequency three-phase asynchronous motor (frame size 355-800) is a series of products developed on the basis of the original Y/YKK series high-voltage motors. This series of motors is used in conjunction with the inverter to control the running speed of the motor to meet the production requirements of industrial and mining machinery and equipment. This series of motors has a strong universal type, and its voltage level and power level are equivalent to Y and YKK high-voltage squirrel cage motors, enabling non-discriminate replacement.
YPKK variable frequency high voltage motors comply with IEC international standards, and the mechanical dimensions and tolerances of each component comply with the corresponding national and international standards.
YPKK series high-voltage variable frequency three-phase asynchronous motor also adopts box type structure. The base is welded by steel plate, which is light in weight and good in rigidity. The YPKK high voltage motor is enclosed with an independent variable frequency air-to-air cooler on top of the motor.
YPKK variable frequency high-voltage motor stator winding adopts Class F heat-resistant insulating material, the top binding is reliable, and the vacuum pressure immersion paint makes YKK high-voltage motor have good insulation performance and mechanical strength. The rotor is a squirrel-cage structure with a reliable cast aluminum or copper conductor. Bearings are available in both rolling and plain bearings.
YPKK high-voltage variable frequency three-phase asynchronous motor can be used in power stations, water plants, petrochemicals, metallurgy, mining and other industries. Such as compressors, pumps, fans, and other mechanical equipment. The motor has the advantages of high efficiency, low noise, low vibration, light weight, reliable quality, convenient installation and maintenance.
