A two-pole generator rotor assembly (100) including a core (120) and a shaft for mounting the core (120). The shaft includes a pair of shaft end portions (117, 119), with each of the shaft end portions (117, 119) including an integrally formed axially extending retaining wedge portion (134) adapted to mount and retain the core (120) in the rotor assembly (100). The wedge retaining portions (134) include opposed surface portions arranged so as to define therebetween a slot for accommodating the core (120) when the shaft end portions (117, 119) are assembled so that the core (120) and shaft end portions (117, 119) form a rotor subassembly. An outer containment (114) is shrink fitted on the rotor subassembly. A tongue and groove connection (38a, 39) is provided between the respective retaining wedge portions (134) and associated shaft end portions (117, 119) so as to interlock the two end shaft portions (117, 119) together.

A package for a high power electrical component includes a base and a plate disposed on a support surface of the base and having an electrically insulative layer and an outer layer having a conductive portion thereon. An electrically conductive pad is disposed on the electrically conductive portion of the plate and the electrical component is disposed on the pad. A cover is disposed atop the base and encloses the plate, the pad and the electrical component. First and second electrically conductive terminals extend through apertures in the cover and are electrically coupled to the electrodes of the electrical component. The cover is hermetically sealed to the base and to the first and second terminals. The coefficient of thermal expansion of the base and cover are substantially equal to minimize stresses developed therein.

A rotor assembly including first and second generally discoidal endshafts disposed at opposite ends of the rotor assembly, an electromagnetic core and winding assembly secured between the endshafts, and a generally annular sleeve member shrunk-fit onto the end shafts in a position surrounding the electromagnetic core and winding assembly. The torque is transmitted through the sleeve member between the endshafts during operation of the dynamoelectric device in which the rotor is employed. A method of assembling the rotor is also disclosed in which the electromagnetic core and winding assembly is bolted between the endshafts. The sleeve member is heated to a temperature between 900.degree. and 1,000.degree. F., the sleeve member is brought into a position over the endshafts, and subsequently allow to cool to ambient temperature to shrink into locking engagement with the endshafts.
