Abstract

1,171,903. Transformers. SERVOMEX CONTROLS Ltd. 22 Nov., 1965 [5 Oct., 1965], No. 42227/65. Heading H1T. [Also in Division G3] A transformer assembly includes a variable transformer 10 having a return spring 18 to restore the output tap to a minimum output voltage position when a servomotor controlling the output tap is rendered inoperative. The assembly provides a voltage stabilizer (see Division G3) in which the motor is supplied with bias and error signals to vary the output tap to boost or buck a transformer in the supply circuit (Figs. 1, 3, not shown), the motor being de-energized when the supply fails. A variable autotransformer comprises a toroidal winding contacted by a brush 16 on an arm 15 keyed to a shaft 17 carrying a sprocket 21 enabling coupling to the servomotor, and a drum 20, 20<SP>1</SP> about which the return spring 18 is wound and anchored.
