In this paper, the authors investigate the half synchronous speed operation of induction motors gained by the various methods of unsymmetrical rotor-winding connections by the use of the equivalent circuit and actual measurement. And also they inquire the method of improving the characteristics of the halfspeed operation. The summary of the results is shown below. The output of induction motors at halfspeed decreases about one-half of the normal rated output because the rated voltage cannot be applied, and the stator current increases rapidly when the output increases above one-half of the normal rated output. But, by connecting the external capacitor with one phase of unsymmetrical rotor-winding connection, this halfspeed operation is more efficient than the operation without the external capacitor, and the output of this halfspeed operation increases about twice as much as the operation without the external capacitor.
