  • Patent number: 10523072
    Abstract: An electric machine may include a plurality of sections, each defining a permanent magnet pocket and a field formation chamber. The sections may be stacked to form a rotor such that when walls of the permanent magnet pockets are aligned from end to end, walls of the chambers of at least some of the sections are offset. An adjacent pair of the sections may have different chamber to pocket relative positions to define different pole arc angles. A difference between the first pole arc angle and the second pole arc angle may be equal to a slot pitch of a stator of the electric machine. The slot pitch may be 7.5 mechanical degrees. The chamber may be defined on a radially outward edge of the pocket. The chamber may taper in a radially outward direction.
