1528877 Induction generators BORG WARNER CORP 16 Aug 1976 [15 Sept 1975 (2)] 34011/76 Heading H2A An induction machine 50 which is mechanically driven to operate as a generator has a short-circuiting switch 60 connected across its output terminals 52, 53, the switch being operable by a control circuit, e.g. of the type shown, whereby to short-circuit the terminals 52, 53. With appropriate choice of the timing and duration of the short-circuiting in each output cycle, mechanical energy can be transformed into field energy, and a magnetic field in the machine can be sustained. |
