Multi-facet partial air deflector

A totally-enclosed fan-cooled motor, comprising:

• a stator provided in an air-tightly closed motor housing;
• a rotor provided oppositely to the stator and mounted to a rotation shaft;
• a pair of bearings for holding a drive side and a side opposite to the drive side of the rotation shaft;
• an external fan provided on the side opposite to the drive side of the rotation shaft and outside the motor for sending wind to the motor housing;
• an air deflector mounted to an endplate disposed on the drive side so as to be located on an outer side of the bearing and the endplate holding the drive side of the rotation shaft, outside the motor and in the vicinity of the bearing for cooling the bearing holding the drive side of the rotation shaft, wherein the air deflector includes:
• a plurality of faceted surfaces disposed at obtuse angles relative to each faceted surface about a periphery of the air deflector directed to deflect wind across the endplate and the drive side bearing, and
• a wind direction guide provided on the drive side for receiving wind sent from the external fan to change a direction of the wind toward the endplate and drive bearing.
