Abstract: A dynamoelectric machine 20 includes a rotor assembly 24 and a main lead insulating assembly 26. The rotor assembly 24 includes a shaft 28 having a main lead receiving recess 32 in its outer surface, a rotor 30 mounted to the shaft 28, and a stator 22 surrounding the rotor 30. The main lead insulating assembly 26 lines the main lead receiving recess 32 and includes at least one insulating bottom block 34 axially secured to the shaft 28 and at least one insulating sidewall block 40 secured to the at least one insulating bottom block 34 with at least one interlocking joint 42. A main lead 35 is received in the main lead insulating assembly 26.

Abstract: A generator rotor lead path configuration includes a plurality of electrically conductive components attached to each other. These components may include a cleat and a wedge. The improved lead path inhibits, if not prevents, lead path failure. A method of assembling or fitting the lead path into a generator is also provided, as well as a method of replacing or retrofitting a lead path that is susceptible to failure with the improved lead path configuration. Assistance in determining causes of lead path failure and ways to overcome lead path failure are also provided.
