  • Terminal lead insulator assembly for wound field synchronous machine
    Patent number: 8373318
    Abstract: A terminal lead insulator assembly for use in a wound field synchronous machine has a generally cylindrical skirt extending in a first direction from a radially larger face. The radially larger face is formed with a plurality of radially outwardly extending ears. The ears include central openings for receiving electrical connections. A rotor assembly, a wound field synchronous machine and a method of assembling such a rotor assembly, each of which include the terminal lead insulator assembly as mentioned above, are also disclosed and claimed.
    Type: Grant

  • Pole count changing generator
    Patent number: 7969122
    Abstract: Disclosed is a pole count changing generator capable of altering the number of poles contained within a generator. This pole count change is accomplished by changing the path through which electrical current is capable of traveling in response to a control signal sent to a pole count changing circuit.
