Disclosed is a coil support for an electrical machine including a shank having a first outer diameter configured to support a field coil of the electrical machine and a base located at one end of the shank. The base has a second outer diameter greater than the first outer diameter and includes a plurality of recesses configured to increase a cooling flow through the electrical machine. Further disclosed is an electrical machine including the coil support and a method for cooling an electrical machine.

Coil support for rotating electrical machine

Disclosed is a dynamoelectric machine having improved heat dissipation capabilities. The dynamoelectric machine includes a three-phase stator winding with a rectifier assembly electrically connected to the stator winding. The rectifier assembly includes an end frame having at least one negative diode contained therein and a positive heat sink which has at least one positive diode disposed therein. Connecting the negative diodes and positive diodes is a terminal assembly. The terminal assembly includes one or more electrically conductive and heat dissipative straps. The straps electrically connect one or more negative diodes and one or more positive diodes. Also disclosed is a method for dissipating heat from a rectifier of a dynamoelectric machine.
