Abstract

175,084. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 16, 1920. Alternating-current motors; field magnets, dampers on poles of.-A synchronous motor carries a double squirrel-cage winding on the rotor, to enable the machine to be started as an induction motor and also to prevent hunting by acting as a damper. The high-inductance squirrel-cage winding consists of a small number of bars 23 of large cross-section, a single bar being located in the middle of each pole-face. These bars are connected to end rings 24, and in order to reducethe resistance additional conductors 26 are placed under the pole tips and connected to the end rings. The high-resistance low-inductance winding consists of a greater number of smaller bars- 20, extending through the pole faces and connected to end rings 21. In the figures, four high-resistance bars are shown per pole, but a modification is described in which there are eight such bars per pole, and the conductors 26 are dispensed with, bars similar to the bars 23 being placed across the end rings in the spaces between each pair of poles.
