Abstract:
A method of winding an electrical rotating apparatus comprising:determining a desired number of phases that is output from said electrical rotating apparatus, wherein said number of phases is greater than three;providing a stator comprising a plurality of slot pairs, each of said slot pairs comprising a first slot and a second slot, wherein the number of said slots is greater than or equal to twice said number of phases;providing a rotor electromagnetically coupled to a magnetic field generated by said stator;providing a plurality of coils that are around said stator, wherein said coils comprise:a first coil coupled to a first slot pair; anda second coil coupled to a second slot pair, with said first slot of each slot pair being on the right side of a reference line dividing said stator in half, and said second slot of each slot pair being on the left side of said reference line, wherein when said first coil is inserted in said first slot of said first slot pair and when said second coil is inserted in said first slot of said second slot pair, said first coil and said second coil being wound around said stator in directions opposite to each other.
