Abstract: 528,881. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1939, No. 14614. Convention date, May 18, 1938. [Class 38 (iii)] The application of excitation to the field 3 of a synchronous motor 1 is effected under the control of a transformer 40 having a primary winding 42 supplied from the source 5 through a rectifier 11, and a secondary winding 43 supplying a control relay 10. The core of the transformer is provided with an air gap bridged at predetermined points in the path of movement of the rotor of the motor, by a member 45 coupled to the motor. The relay 10 is sufficiently energized to cause operation of the field switch 7 only when the air gap is bridged for substantially a full half-wave of energization of the primary winding, and this occurs when the motor approaches synchronous speed. The field switch is maintained over back contacts of the relay 10, and the operation of the field switch transfers the energization of the relay to the secondary of a second transformer element 50. Thus the field switch is retained until the motor loses synchronism and the relay 10 is energized sufficiently from the secondary of this second transformer. The rectifier 11 may be in the secondary circuit of the transformer. Specifications 497,354 and 525,056 are referred to.
