Abstract

978,247. Synchronous motors. FIRST ELECTRIC CORPORATION OF SOUTH AFRICA Ltd. Dec. 12, 1963 [Jan. 7, 1963], No. 49077/63. Heading H2A. The wound rotor 12 of a synchronous induction motor is D.C. excited during normal running from an additional winding and rectifiers 15 also carried on the rotor. The additional winding is excited by field winding 14 when the brushes 13 are raised in the usual way after the starting sequence.
