Technical Examples

A method for greatly reducing magnetic sound of an alternating current rotating machine compared with the past comprising superimposing an n?1-th order frequency in inverse turn on a multi-phase alternating current with reference to a basic frequency component of the multi-phase alternating current supplied to an armature of the alternating current rotating machine of multiple phases so as to reduce the n-th order harmonic components of the basic frequency component among radial direction magnetic vibrating forces generated in the radial direction in a core of the alternating current rotating machine.
