摘要： 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.

The rotor has two stages (14a, b) arranged one at either end of the bars. The bars have a shoe (18a, 8) at each end of each bar that links magnetic flux through the bars with said magnets on each stage. Adjacent shoes facing the same stage of the rotor have a high-reluctance shoe gap (27) between them; adjacent magnets on each stage of the rotor have a high-reluctance magnet gap (25) between them; and the shoe and magnet gaps (25, 27) are angled with respect to each other such that they engage progressively as the rotor rotates. Alternatively, the shoes facing each stage are in a ring of connected shoes such that the magnets experience a continuous reluctance that is at least 90% constant as a function of rotor position. The bars (16) and shoes (18) are formed separately from one another and at least a part of each is formed by moulding soft-iron particles so that the particles have a short dimension that is arranged transverse a reluctance-plane. The bars and shoes are assembled so that the reluctance-plane of the bar is parallel a longitudinal axis (16a) of the bar and said reluctance-plane of the shoe is transverse said longitudinal axis.

摘要： 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.
