A rotary machine type quadruple frequency converter of which a stator is mounted with a primary and a secondary winding having a pole ratio of 1 to 4. The rotor is arranged to have the same number of poles as the number of poles of the primary winding. The rotor pole is arranged to have a shape for producing magnetic flux of 4th harmonics of the source frequency which is supplied to the primary winding. A quadruple frequency power is generated on the secondary winding operating the converter with the source frequency power.
