    • The motor (72) includes a stator affixed to a motor housing (14).The stator has two sets of series connected coils (39a, 39b) (39c, 39d) wound in quadrature. Each set of coils is disposed in an annular configuration about a spin reference axis (Z), with the principal axis of each coil being substantially parallel to the reference axis. The motor further includes a rotor (42, 44) which is adapted for continuous rotation about a spin axis. The rotor includes a set of permanent magnets (46, 48) and a member (42a, 44a) for supporting the magnets in a substantially annular configuration about the spin axis. The magnet moment of each of the magnets is substantially parallel to the spin axis, with the magnetic moment of adjacent magnets being oppositely directed. The rotor is positioned with respect to the stator with the configuration of magnets being adjacent to the configuration of coils so that flux from the magnets is coupled to the coils. The rotor also includes a return ring (50) for establishing a magnetic flux return path for completing a circuitous path for flux passing through the coil. An excitation network (70) for the coils detected back emf in the respective coils, and in response thereto, generates control signals for driving alternating currents in the respective sets of coils. The alternating currents have a 90` relative phase shift and are in phase with the detected back emf for the respective sets of coils.

    • The invention relates to a self-levelling seating platform which does not require actuators or motors to self-level. The seating platform is designed for use in a vehicle. It allows movement in two axes to counteract the motion of a vehicle, thereby maintaining a user of the seating platform in a substantially level position with respect to the horizon. The self-levelling seating platform (10) includes a first frame (12) pivotally attached to a second frame (16) which allows pivotal motion of the first frame relative to the second frame, said second frame being pivotally attached to an outer frame (22) to allow pivotal motion of the second frame relative to the outer frame wherein the pivotal motion of the first frame with respect to the second frame is substantially at right angles to the pivotal motion of the second frame with respect to the outer frame.

    • The present invention provides a structure for isolating the reaction forces generated by a planar motor. Specifically, the fixed portion of the reaction motor, which is subject to reaction forces, is structurally isolated from the rest of the system in which the planar motor is deployed. In accordance with one embodiment of the present invention, the fixed portion of the planar motor is separated from the rest of the system and coupled to ground. The rest of the system is isolated from ground by deploying vibration isolation means. Alternatively or in addition, the fixed portion of the planar motor may be structured to move (e.g., on bearings) in the presence of reaction forces, so as to absorb the reaction forces with its inertia. In a further embodiment of the present invention, the fixed portion of the planar motor and the article to be moved are supported by the same frame, with the fixed portion of the planar motor movable on bearings.
    • 本发明提供了用于隔离由平面电动机产生的反作用力的结构。 具体地,反应电动机的受到反作用力的固定部分与其中布置有平面电动机的系统的其余部分结构地隔离。 根据本发明的一个实施例,平面电动机的固定部分与系统的其余部分分离并耦合到地面。 系统的其余部分通过部署隔振装置与地面隔离。 或者或另外,平面电动机的固定部分可以被构造成在反作用力的存在下移动(例如,在轴承上),以便以其惯性吸收反作用力。 在本发明的另一实施例中,平面电动机的固定部分和待移动的物品由相同的框架支撑,平面电动机的固定部分可在轴承上移动。
