Abstract

1,190,482. Control of A.C. motors. JANOME SEWING MACHINE CO. Ltd. 7 Feb., 1968 [7 Feb., 1967; 27 March, 1967; 25 Sept., 1967], No. 6160/68. Heading H2J. [Also in Divisions D1, G3 and H1] A commutator motor 3 is energized from an A.C. supply through a symmetrical semiconductor element SSSM using both wave omission and phase angle control. SSSM is made to conduct asymmetrically for positive and negative half-cycles by pulses from a pulse transformer P.T. in the primary of which is a similar semi-conductor SSST, the conduction of which is controlled by the setting of a potentiometer V.R. and the back e.m.f. of the motor.
