    • An electric machine (100) comprises a stator (112) and a rotor (114a, b) mounted for rotation about a rotor axis (120) with respect to the stator. Permanent magnets (124a, b) are carried by the rotor. The rotor has an output (190). The stator has coils (122) wound on stator bars (116) for interaction with the magnets. The rotor has two stages (114a,b) arranged one at either end of the stator bars, with two air gaps (126a,b) between the ends of the bars and the rotor stages. An annular housing (102, 142a, b, 146) retains and mounts the stator. A bearing (164a, b) is between the rotor and stator, the rotor being hollow around said rotor axis. There are two significant magnetic flux paths (30,30′) of the motor. The first passes between adjacent coils in a circuit on a substantially circumferential plane with respect to the axis (120). A second path 30′ is in an axial plane, passing around the bearing. The stator coils are spaced around the rotor axis and approach the rotor axis no closer than a first, stator radius (R1) of the stator. The bearing comprises rolling elements rolling on a surface of the rotor that is no closer to the rotor axis than a second, rotor radius (r), which rotor radius is between 60% and 90% of the stator radius.
    • 电机(100)包括定子(112)和安装成围绕转子轴线(120)相对于定子旋转的转子(114a,b)。 永磁体(124a,b)由转子承载。 转子具有输出(190)。 定子具有缠绕在定子棒(116)上的线圈(122),用于与磁体相互作用。 转子具有两个级(114a,b),它们在定子杆的任一端设置一个,在杆的端部和转子级之间具有两个气隙(126a,b)。 环形壳体(102,142a,b,146)保持和安装定子。 轴承(164a,b)位于转子和定子之间,转子围绕所述转子轴线是中空的。 电动机有两个明显的磁通路径(30,30')。 电路中的相邻线圈之间的第一通路相对于轴线(120)在基本上圆周的平面上。 第二路径30'处于轴向平面中,绕轴承穿过。 定子线圈围绕转子轴线间隔开并且接近转子轴线不比定子的第一定子半径(R1)更近。 该轴承包括在不超过定子半径的转子半径在60%至90%之间的转子半径(r)不超过转子轴线的转子表面上滚动的滚动元件。
