<p>An electrical rotating machine consisting of an induction machine operated by an inverter drive system, wherein many phases are used in place of the conventional three. The use of many phases has benefits not anticipated by the art, the most important of which is the use of harmonic rotating fields which cause efficiency losses in conventional three phase induction machines. The method of the present invention is applicable to induction machines of all types, including motors and generators, and allows for higher efficiency and greater torque capabilities. The method of the present invention may further make use of many of the advances in inverter technology, however the harmonic tolerance of the many phase motor makes possible the efficient use of less advanced and less expensive inverter drive systems.</p> |
