Y, YKK, YKS series Medium/Large Size High Voltage AC motor is suitable for poor surroundings, the site in high required protection and directly application of outdoor. The motors can drive water pump, compressor, transportation machinery and common used machinery.

Y, YKK, YKS series motors are permitted to start at full voltage. It is not allowed to make short circuit connection on rotor winding directly, it is necessary to regulate starting torque by the way of connecting starting transform.

The motor is design into box type construction. The frame is light in weight and good in rigid and is made of steel plates by melding. Air-water cooler is fixed at the top of frame with bolts and consists outside wind circuit in secondary cooling with water pump and water pool for motor, the primary cooling circulation is consisted of fan, cooler inside motor. The primary cooling medium (air) can complete the heat exchange with secondary cooling medium in cooling pipe (circulation water) through outside surface of pipe in the cooler as well as spring etc. Heat transfer conductor.

The rotor winding of Y, YKS,YKK series motor is made of aluminum casting or copper bar.
