A V-block with a preselected shape defining a preselected included angle between a pair of V-block side portions is connected to a laminated spider of a rotor at preselected location between spaced apart adjacent poles of the rotor by disposing an elongated connecting piece in a slot longitudinally disposed in the spider and connecting the elongated connecting piece to the V-block by a fastener. Applying a preselected torque to the fastener establishes a predetermined force between the V-block and the conductive windings disposed about adjacent poles. The V-block arrangement is particularly suited for use in a dynamo-electric machine.

An integral heat sink and fan rectifier assembly comprises a disk fastened to a rotor of a synchronous motor or generator, the disk having a central bore, a plurality of fan blades disposed on the outer periphery and a circular array of recesses that receive insulation encapsulated rectifier units that are fastened to the disk and a have a heat transfer plates that engage the bottom of the recesses to transfer heat to the disk which conducts the transferred heat to the fan blades, which transfer the heat to the cooling air as rotor rotates and blows cooling air through a portion of the motor or generator.
