    摘要: A motor includes a stator, a rotor, and a case. The stator includes a stator core and windings. The rotor is provided inside the stator. The rotor includes first and second rotor cores and a field magnet. The first and second rotor cores each includes a core base and claw-shaped magnetic poles. The core bases are opposed to each other and the claw-shaped magnetic poles of the first and second rotor cores are alternately disposed in a circumferential direction. The field magnet is disposed between the core bases in the axial direction. The field magnet is magnetized in the axial direction so as to cause the claw-shaped magnetic poles of the first rotor core and the second rotor core to function respectively as first magnetic poles and second magnetic poles. At least part of an end part of the case in the axial direction is made of a non-magnetic body.

    摘要: A supporting member on which a wafer table is mounted is substantially kinematically supported, via six rod members placed on a slider. Further, coupling members are placed facing in a non-contact manner via a predetermined gap, thin plate-shaped edges provided at both ends in the Y-axis direction of the supporting member. By this arrangement, vibration-damping is performed by the coupling members (squeeze dampers) facing the edges, on vibration of the supporting member mounted on the wafer table. Further, because the supporting member is kinematically supported via the plurality of rod members, it becomes possible to reduce deformation of the wafer table that accompanies deformation of the slider.

    摘要: An on-board fluid machine includes a housing configured to allow fluid to flow into the housing, an electric motor accommodated in the housing, and a driver that is supplied with DC power and drives the electric motor. The driver includes a low-pass filter circuit and an inverter circuit. The low-pass filter circuit includes a common mode choke coil and a capacitor. The driver further includes a damping unit located at a position where magnetic field lines produced by the common mode choke coil generate eddy current.

    摘要: A mechanically commutated electric motor is at least partially arranged in a closure apparatus for a housing. The closure apparatus includes at least a first rod-like throttle coil and a second rod-like throttle coil which are wound in opposite directions with coil wire and which are arranged parallel to one another. The first throttle coil is electrically directly coupled to a first coupling element provided for electrical coupling to the mechanically commutated electric motor, and the second throttle coil is electrically directly coupled to a second coupling element provided for electrical coupling to the mechanically commutated electric motor, such that, when the mechanically commutated electric motor is connected to the coupling elements and the mechanically commutated electric motor is operated, the magnetic fluxes (Phi1, Phi2) in the first throttle coil and second throttle coil at least partially compensate one another.

    摘要: An electric machine for a motor vehicle, includes a rotor, and a stator. The stator has a coil device for generating a magnetic rotary field for driving the rotor. the coil device has a soft magnetic flux-guiding device for guiding the rotary field, wherein the coil device is only partially arranged in the flux-guiding device, wherein at least one winding overhang of the coil device extends out of the flux guiding device into an environment of the stator. The electric also includes and an electrically conductive shielding element arranged on the at least one winding overhang and configured to electrically and/or electromagnetically shield the winding overhang against an environment, wherein the shielding element is connected to a frame potential connection of the electric machine.
