Loose and inlay double -deck lap winding structure of circle that varies

The utility model relates to a loose and inlay double -deck lap winding structure of circle that varies, including the multiunit coil, the coil adopts two multilayer component wire winding modes to form the winding, and every group loop diameter is different, each lies in the number of turns difference that coil cross -section orientation was respectively organized to each stator slot in organizing coil difference setting -in income stator slot, the utility model discloses in mainly used three -phase asynchronous motor dipolar, quadrupole, the sextupole motor, comparing circle winding such as double -deck lap wound and having that sparingly copper is heavy, miscellaneously consume lowly, high efficiency, the number of turns such as can finely tune at the advantage, the dense winding mode that varies has more superior electromagnetism nature, and flux density is more reasonable, through suitable ampere -turn distribution, can there be higher electric efficiency at the on the premise of of saving with the copper volume, at the on the premise of of great saving enameled wire copper wire cost, obtain higher electric efficiency and lower winding temperature rise.
