摘要

An electric machine includes a rotor and a stator. The stator includes a stator core having a plurality of slots. The stator further includes a plurality of drive modules configured to collectively produce an aggregate rotating magnetic field. Each respective drive module includes a power supply configured to generate a respective poly-phase alternating current (AC) output and is connected to a plurality of respective conductor windings. Each respective conductor winding includes a plurality of respective conductors, each respective conductor configured to carry a respective phase of the respective poly-phase AC output. Each respective drive module is configured to generate a rotating, poly-phase, multipole magnetic field. The rotating, poly-phase, multipole magnetic field is a superimposition of a plurality of respective mono-phase, multiple magnetic fields being generated by a respective conductor of the respective conductor winding.

說(shuō)明書

The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
