Abstract

1293291 Automatic control of speed TOKYO SHIBAURA ELECTRIC Co Ltd 14 Jan 1971 [16 Jan 1970(2) 11 June 1970 (2)] 1798/71 Heading G3R [Also in Division H2] The speed of a brushless motor (see Division H2) is controlled by varying the voltage fed to the static commutator SRC energising the stator windings U,V,W in dependence on the difference between the desired and actual speeds of the motor. The thyristor commutater shown is supplied from a variable d.c. source 1c whose output voltage is varied in dependence as the difference between a tachometer output voltage G and a reference voltage Rd.
