Abstract: In a preferred form, a brush-holder assembly for dynamoelectric machines includes a support plate formed with a yieldable clip for holding a brush in a retracted position by engaging the brush shunt wire. The brush is held retracted to prevent its interference with the machine rotor when the rotor is assembled to a case part. The brush is released by depressing the yieldable clip out of the path of the shunt wire so that the shunt wire is disengaged.

Abstract: In a preferred embodiment, a rotor for a dynamoelectric machine and method for manufacture includes a laminated rotor core mounted on a shaft sleeve which is mechanically expanded by an interference fit with the motor shaft. A pair of rotor end supports are mounted on the shaft sleeve in an axially supporting relationship with the ends of the rotor core and in a circumferentially supporting relationship with the ends of a winding carried by the rotor core.

Abstract: In a preferred form, a bearing support assembly for dynamoelectric machines carries one end of the machine shaft so as to limit axial shaft movement. The shaft end is rotatable in a bearing which is axially confined on the shaft by a thrust collar. First and second annular retaining springs are mounted in the end of one of the housing case parts so as to provide support for opposite sides of the bearing. The method of assembling the shaft to the case part includes mounting the first retaining spring, the bearing, and the thrust collar to the shaft end and mounting the second retaining spring within the case part. The shaft is inserted axially into the case part so that the bearing initially engages the second retaining spring. The shaft end is pressed further until the first retaining spring snaps into place within the case part, whereupon the bearing support assembly is completed and the shaft end is supported therein with a predetermined axial end play.

Abstract: In a preferred form, a cooling arrangement for a squirrel cage rotor assembly of an alternating current electric drive motor includes a pair of rotor end plates clamped to the ends of a rotor core carrying a pair of conductive end rings extending from the ends of the rotor core. The rotor end plates form end ring cooling cavities circumscribing the inner peripheries of the end rings. The rotor core is carried by the motor shaft and a recessed area on the outer diameter of the shaft forms axial cooling channels in heat conducting relation with the inner bore of the rotor core. A pair of concentric axial shaft passages extend through a bore in the center of the shaft and communicate with radial shaft passages connected with the end ring cooling cavities and with the axial cooling channels. A hollow insert is mounted in the shaft bore for separating the pair of axial shaft passages. A liquid coolant is circulated from one end of the shaft through the end ring cooling cavities and the annular cooling chamber to transfer heat from the end ring and the rotor core.

Abstract: A conduit arrangement is described for conducting a liquid coolant between stationary and rotating parts of a liquid-cooled dynamoelectric machine. One conduit end is rotatably mounted in a self-aligning bearing supported in the stationary part and the other end is mounted for universal movement within the passage opening of the rotating part. The conduit is rotated by a pin extending into the passage of the rotating part.

Abstract: A dynamoelectric machine cooling arrangement is disclosed for a brushless alternating current generator including an integral rectifier assembly. Rotating parts mounted on the machine shaft are cooled by annular pools of liquid coolant which are circulated around annular supporting portions of the rotating parts. A rectifier support wheel mounted on the shaft has an annular cooling chamber. Heat sinks for supporting radially oriented semiconductor diodes are mounted within the annular chamber and are cooled by an annular pool of coolant supplied by a coolant flow directed over the semiconductor diodes. Coil end turn supports mounted on the shaft include annular reservoirs for containing annular pools of coolant with a coolant flow being directed thereto form radial passages provided in the shaft.
