摘要： A dynamoelectric machine stator has a primary winding for single phase alternating current input and a secondary winding for polyphase alternating current to be supplied from output terminals. The secondary winding is connected such that at least two frequencies are provided at the terminals. The rotor has two windings thereon for excitation, one being excitable for one frequency output and the other rotor winding being excitable for another frequency output at the secondary terminals. Another secondary winding may be provided on the stator to obtain a desired output terminal voltage at one of the selected frequencies.
