ABSTRACT:
An induction motor comprises a stator and rotor totally enclosed in a case with no air communication through the case, an internal shaft mounted fan at each end of the rotor and an external fan and fan shield at one end to direct cooling air along the outer surface of the case. The motor is further provided with hollow, toroidal baffles internally at each end which force the air within the case at each end of the motor to be circulated across the bearing and ends of the windings to pick up heat and along the internal surface of the case to exchange the heat through the case with the fan driven outside air. A further improvement is the provision of an air channel from the fan shield along the outer surface of the case to the other end of the motor and radial ducts from the channel to the interior of the baffle and from the opposite side of the baffle to the case, whereby a portion of the fan driven external cooling air is forced through the interior of the driving end baffle. Another improvement is the provision of a lower axially extending inlet duct and an upper radially extending outlet duct for the fan end baffle for air to be driven therethrough by the external fan.
