ABSTRACT:
A rectifier assembly for use in a rotating electromagnetic machine includes an outer heat sink and an inner heat sink. The outer heat sink is configured to be connected with a diode wheel rim such that an air space is defined therebetween for cooling during rotation of the diode wheel rim. At least one rectifier element is disposed between and electrically connected with the outer heat sink and the inner heat sink. A block is disposed adjacent to the outer heat sink generally opposite the at least one rectifier element. A clamping bolt extending through the inner heat sink and the outer heat sink is threadingly engaged with the block. An electrically insulating tube is disposed around the clamping bolt. An elastomeric spacer is positioned around the clamping bolt on an end of the tube. The spacer is configured to accommodate axial stack-up tolerances of the rectifier assembly in an axial direction of the clamping bolt.
