YKK series medium-size high voltage 3-phase Squirrel cage asynchronous motors have good performance such as efficiency, energy conservation, lower noise, slight vibration, reliable operation, convenient installation and maintenance.
YKK series motors are suitable for driving compressor, water pump, crack machine, cut machine, transportation machine and other equipments. It is also used as the primitive drive for the mine mechanical industry, petroleum & chemistry industry, power plant and so on.
The motor has the box-type construction, which was made up of steel plates welded with each other, lightweight and good stiffness. On top of the motor is the air- air cooler, convenient to maintenance and replacement. The stator adopts the press construction. The winding is with class F insulation and VPI impregnating, which ensures the reliable of the insulation, the mechanical stress and the capable of resistant humidity.
