Abstract: A permanent magnet electric machine with reduced cogging torque includes a plurality of axial rotor sections that are defined on a radially outer surface of a rotor. The axial rotor sections include a set of permanent magnets that are in an unmagnetized state and that have opposite edges that are aligned with an axis of the rotor. The axial rotor sections are rotationally offset such that the edges of the permanent magnets create stair step interfaces. The n sets of permanent magnets are magnetized using a magnetizing fixture. The permanent magnets have a generally rectangular shape and are preferably arc magnets or breadloaf magnets. The conductors of the magnetizing fixture are aligned with the stair step interfaces. A magnetic field induced in the permanent magnets is substantially reduced along the stair step interfaces.

A bearing receives the shaft for rotatably mounting the rotor. A stator assembly is mounted on said bearing and includes a bobbin mounted generally coaxially with the rotor shaft and having an interior diameter, an exterior diameter, a first axial end and a second axial end. A winding is wound on the bobbin and extends around the axis of the rotor shaft. The winding has a width in a direction parallel to the lengthwise extension of the rotor shaft. Plural separate ferromagnetic members are on each of the first and second axial ends of the bobbin. Each ferromagnetic member has a radially outer leg extending generally between the winding and the magnet. The outer legs of the ferromagnetic members on the first axial end of the bobbin extend generally from the first axial end of the bobbin toward the second axial end and the outer legs of the ferromagnetic members on the second axial end of the bobbin extend generally from the second axial end toward the first axial end.

Abstract: A laminated rotor for an induction motor has a plurality of ferro-magnetic laminations mounted axially on a rotor shaft. Each of the plurality of laminations has a central aperture in the shape of a polygon with sides of equal length. The laminations are alternatingly rotated 180° from one another so that the straight sides of the polygon shaped apertures are misaligned. As a circular rotor shaft is press fit into a stack of laminations, the point of maximum interference occurs at the midpoints of the sides of the polygon (i.e., at the smallest radius of the central apertures of the laminations). Because the laminates are alternatingly rotated, the laminate material at the points of maximum interference yields relatively easily into the vertices (i.e., the greatest radius of the central aperture) of the polygonal central aperture of the next lamination as the shaft is inserted into the stack of laminations. Because of this yielding process, the amount of force required to insert the shaft is reduced, and a tighter fit is achieved.

Abstract translation: 用于感应电动机的层压转子具有轴向安装在转子轴上的多个铁磁性叠片。 多个叠片中的每一个具有呈多边形形状的具有相等长度的边的中心孔。 叠片交替地彼此旋转180°，使得多边形孔的直边不对准。 由于圆形转子轴被压配合成叠片，所以最大干涉点出现在多边形侧面的中点（即在叠片的中心孔的最小半径处）。 由于层叠体交替旋转，所以当最大干涉点处的层压材料插入到堆叠中时，相对容易地进入下一叠层的多边形中心孔的顶点（即，中心孔的最大半径） 的叠片。 由于这种屈服过程，减少了插入轴所需的力的量，并且实现了更紧密的配合。
