Title: Improved means for controlling the speed of electric motors
IPC: H02P29/00
Filed: 1937-10-20
Abstract: 500,893. Automatic control systems. RAWLINGS, A. L. Oct. 20, 1937, No. 28595. [Class 38 (iv)] Speed.-An electric motor is maintained at constant speed by a clock or escapement device and a device responsive to the motor speed operating in combination upon the circuit of the motor. A contact 8 carried by a spring 7 on the motor shaft 3 and a contact 9 on a screw 10 within a nut 11 are connected respectively to the ends of a resistance in the field circuit of the motor. The screw 10 is driven by the clock 23 and the nut rotates in a bearing 12 and is driven through reduction gear by the motor 1 so that no contact 9 is stationary so long as the number of revolutions made by clock and motor in any period agree. Excessive speed of the motor will short circuit the resistance and cause a fall in its speed. In a modification, the escapement mechanism is mounted in a casing free to turn on a shaft driven by the motor and driving the escapement; so that the casing remain stationary when clock and motor speeds agree; the casing is geared to drive the contact-carrying screw against a spring. The device responsive to motor speed may be a centrifugal governor or dependent on drag in a viscous fluid or magnetic field. The motor may drive an A.C. generator for synchronous motor-driven time dials and time setting may be effected by turning the nut 11 relatively to its driving pinion. A synchronous electric motor clock may be used to co-operate with the speed responsive means.
