The stator comprises a plurality of stator coils (12) and a support (30) for holding the coils around a rotor of the motor. A cylindrical sleeve (16) is mounted radially inwardly on the support to form a barrier in use between cooling fluid passing over the coils and a rotor located within the stator. The rotor comprises a hub (73), a plurality of rotor segments (50,72), and a plurality of permanent magnets (56). The segments are arranged around the hub in a ring, with the permanent magnets disposed between the segments. A radially outwardly facing exposed surface (58)of each magnet is spaced radially inwardly from an outer cylindrical profile defined by the segments.

    Abstract: The present invention is a high efficiency permanent magnet machine capable of maintaining high power density. The machine is operable over a wide range of power output. The improved efficiency is due in part to copper wires with a current density lower than traditional designs and larger permanent magnets coupled with a large air gap. In a certain embodiment wide stator teeth are used to provide additional improved efficiency through significantly reducing magnetic saturation resulting in lower current. The machine also has a much smaller torque angle than that in traditional design at rated load and thus has a higher overload handling capability and improved efficiency. In addition, when the machine is used as a motor, an adaptive phase lag compensation scheme helps the sensorless field oriented control (FOC) scheme to perform more accurately.

    Abstract translation: 本发明是能够保持高功率密度的高效率永磁电机。 该机器可在广泛的功率输出范围内工作。 提高的效率部分是由于电流密度低于传统设计的铜线,并且具有大的气隙耦合的较大的永磁体。 在某些实施例中,通过显着地减小导致较低电流的磁饱和度,使用宽的定子齿来提供额外的改进的效率。 该机器在额定负载下也具有比传统设计小得多的扭矩角,因此具有更高的过载处理能力和更高的效率。 此外,当机器用作电动机时,自适应相位滞后补偿方案有助于无传感器场定向控制(FOC)方案更准确地执行。

    Abstract: The rotor unit has a plurality of rotating bodies which is arranged along a central axis. Each of the plurality of rotating bodies has an annular rotor core which surrounds the central axis, a plurality of magnets which is arranged in the circumferential direction around the rotor core, and a holder which holds the magnets. Further, the holder has a plurality of partitioning portions each axially extending between the magnets. The axial dimension of the partitioning portion is longer than the axial dimension of the magnet which is held by the partitioning portions. Further, the plurality of rotating bodies is disposed in a state where the circumferential positions of the plurality of magnets are out of alignment. In this way, contact between the magnets is prevented by the partitioning portion. Therefore, damage to each magnet is suppressed.
