Abstract

1,076,673. Control of A.C. motors. A. A. FINK. May 17, 1965, No. 20659/65. Heading H2J. [Also in Division F1] A linear electric motor driving an hydraulic pump is controlled by a timing motor, e.g. a synchronous motor, driving a reversing switch in circuit with the linear motor. A rheostat is included in the circuit for adjusting the stroke of the motor. In a modification two rheostats are included in the circuit so that the stroke in each direction may be adjusted. In a further embodiment the motor actuates coupled reversing switches at each end of its stroke.
