Title: Control system
IPC: G05D3/12
Filed: 1950-05-26
Abstract: 678,409. Control of motors. BENDIX AVIATION CORPORATION. May 26, 1950. [June 28, 1949] No. 13344/50. Class 38 (iii). [Also in Groups XXXV and XXXVIII] Apparatus for synchronising a rotating slave element with a rotating master element comprises a phase sense conscious device, responsive to the sense of an error signal developed when the slave element is out of synchronism, which selectively energizes a pair of relays to continuously connect a synchronising motor to a power-source, so as to operate in one or other direction dependent on the error signal phase sense and correspondingly to accelerate or decelerate the slave element to restore it to synchronism with the master element. In Fig. 1 the A.C. energized rotor 3 of selsyn 1 is driven by a master rotatory element 12, and the stator 7 is connected to the stator 9 of a similar selsyn 11 whose rotor 13 is driven by a slave rotatory element 15. Asynchronism of the master element relatively to the slave element develops an error voltage across the rotor 13, which is amplified and coupled to the grids of a pair of thyratrons 23, 25, whose anodes are energized in antiphase from an A.C. energized transformer 49 through the coils of relays 63, 65. Current limiting resistors are connected in series with the relay coils and condensers are shunted adross the coils and resistors to prevent chattering. According to the phase sense of the error signal, one or other of the thyratrons conducts on alternate half cycles and energises its associated relay to open contact 84 or 86 and close contact 77 or 79 and connect the field winding 71 or 73 of a synchronising motor 19 across an A.C. power source 69 to accelerate or decelerate the slave element relatively to the master element e.g. by regulating a control potentiometer of a motor driving the slave element, or by driving the slave element through one shaft of a differential whose other shaft is driven at constant speed. On resynchronisation the error voltage falls to zero and the relay is de-energized to open contacts 77 or 79 and close contacts 84 or 86 to connect a D.C. source 82 to the field winding 71, which exerts a braking torque on the motor to prevent hunting. Displacement of a switch 43 from its central position in either direction breaks the thyratron cathode circuit and the D.C. anti-hunt circuit, and energizes either motor field for manual control. A centre zero rectifier meter 7 indicates the direction of motor rotation. In Fig. 3 (not shown) the relay contacts control a 3-phase motor and in Fig. 4 (not shown) a D.C. motor for rotation in either direction.
