  • Foreign object detecting device, wireless power transmitting apparatus, and wireless power transfer system
    Patent number: 10651658
    Abstract: A foreign object detecting device includes first and second coils, the winding directions of which are the same, and a foreign object detecting circuit. The foreign object detecting circuit outputs a first detecting signal having a first predetermined waveform to a first terminal of the first coil and outputs a second detecting signal having a second predetermined waveform, which has the same polarity as the first predetermined waveform, to a third terminal of the second coil to cause magnetic fields generated from the first and second coils to repel each other. The foreign object detecting circuit measures an amount of change of the impedance value of the first or second coil which is caused by the presence of a foreign object. When the amount of change exceeds a predetermined value, the foreign object detecting circuit determines that there is a foreign object above the first or second coil.

  • Resolver
    Patent number: 10627258
    Abstract: In a related-art resolver, a front and a back of a stator core cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator including: a stator core formed of electromagnetic steel sheets, which have teeth, and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor arranged to be opposed to the resolver stator, in which the stator core has marks which enable distinction of a rolling direction of the stator core and distinction of a front and a back of the stator core.
