ABSTRACT:
A magnetically driven motor comprises a housing, an output shaft, a stationary field, a rotating field, a control cylinder and a control cylinder drive motor. The housing and the three pairs of permanent magnets mounted thereon are considered to together define the stationary field of the subject motor. The rotating field consists of a series of permanent magnets at least equal in number to the number of pairs of permanent magnets of the stationary field mounted on the output shaft so as to bear preestablished angular relationships relative to each other and so as to be alignable with the pairs of permanent magnets of the stationary field. The control cylinder consists of a metal cylinder of lesser diameter than the housing of the motor and is supported on the output shaft for relative rotation intermediate the permanent magnets of the stationary field and the permanent magnets of the rotating field. The control cylinder drive motor is supported within the housing of the subject motor and is operatively connected to the control cylinder whereby the rotation of the latter is effected from the former and is independent of the rotation of the output shaft and the rotating field.
