11. A dual redundant permanent magnet type dynamoelectric machine comprising:
-
a first motor; a second motor; a common drive shaft powered by said first motor and said second motor; and a dual flux throttle system to selectively disable one of said first motor and said second motor in response to a detected condition while said common drive shaft is rotated by the other of said first motor and said second motor, said dual flux throttle system includes a first ring and a second ring for operation of a first flux throttle system relative said first motor and a first ring and a second ring for operation of a second flux throttle system relative said second motor. - View Dependent Claims (12, 13)

16. A method of operating a dual redundant permanent magnet type dynamoelectric machine comprising:
-
axially positioning a dual flux throttle system operable to selectively disable one of a first motor and a second motor in response to a detected condition while the other of the first motor and the second motor continues rotating a common drive shaft; and overcoming a spring bias of the dual flux throttle system to disable one of the first motor and the second motor.

18. A dual redundant permanent magnet type dynamoelectric machine comprising:
-
a first motor; a second motor; and a spring bias of a dual flux throttle system to disable one of said first motor and said second motor in response to a detected condition while a common drive shaft is rotatable by the other of said first motor and said second motor.
