Title: Improvements in and relating to magnetic amplifier circuits
IPC: H03F9/04
Filed: 1951-02-21
Abstract: 707,400. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 21, 1951 [March 1, 1950], No. 4226/51. Class 38(3) [Also in Groups XXXVIII. and XXXIX] In a motor control system, a magnetic amplifier (see Group XXXIX) comprising two pairs of saturable reactors connected. in push-pull controls the direction of rotation of a motor in accordance with a signal applied to control windings 22, 23. Control of A.C. motors; a two phase motor 29, Fig. 1, has one phase 31 supplied from an A.C. source 4 over a phase shifting condenser 32, while the other phase 30 is energized from the same source over the magnetic amplifier and a transformer 28. The two pairs of saturable reactors are normally balanced and produce equal opposing D.C. voltage'in load resistors 14, 15 so that phase 30 is not energized. Application of a D.C. signal from potentiometer 24 to the control windings however unbalances the opposed voltages in the load resistors during successive half cycles of source voltage and produces an A.C. component which is applied to phase 30 over the transformer, the phase of the A.C. component being determined by the polarity of the D.C. signal so that directional control is effected. Control of D.C. motors; a motor 47, Fig. 2, is mechanically coupled to a load 48 and to the receiver rotor 46 of a selsyn system 40, 41 having its transmitter rotor 44 energized from an A.C. source 45 which also supplies the magnetic amplifier 35. This amplifier is normally balanced so that a similar amplifier 36 connected in cascade produces no output across resistors 14a, 15a. Lack of correspondence between the rotors 44, 46 however supplies an A.C. error signal to control windings 22, 23 and a resultant D.C. output across resistors 14, 15 is applied to control windings 22a, 23a of amplifier 36. This amplifier also becomes unbalanced and, since its windings 11a, 13a are connected in the reverse manner to the corresponding windings in amplifier 35, produces a D.C. output to the motor across 14a, 15a. The D.C. output polarity is determined by the phase relation of the error signal applied to windings 22, 23 and hence the direction of rotation of the motor to restore correspondence is determined.
