  • Patent number: 10337887
    Abstract: A magnetic sensor includes: a magnetic converging plate; Hall elements disposed on one surface side of the magnetic converging plate; wires connecting with the Hall elements; and a signal processing circuit that connects with these wires to receive a signal from the Hall element. Between the Hall element and the signal processing circuit, the two wires cross while being spaced apart from each other in a depth direction of a substrate, and forms a compensation loop between a cross of the two wires and the circuit, and in a planar view as seen in a depth direction, at least part of a region occupied by the compensation loop is covered by the magnetic converging plate. The compensation loop compensates an induced electromotive force caused to the closed loop formed by the wires including the Hall element.

  • Patent number: 10317245
    Abstract: An electric machine (e.g., motor or generator) for an electric drive system of an electric vehicle is adapted to be coupled to wheels of the vehicle for conversion between stored electrical energy and rotation of the wheels. A resolver is coupled to the electric machine having a rotor rotating with the electric machine, the resolver responding to an excitation signal to produce a position signal. A controller is coupled to the resolver to receive the position signal and coupled to the electric machine to control the conversion. The controller generates the excitation signal at a variable frequency selected as a function of an operating point of the electric machine to avoid harmonic noise peaks propagating at the electric machine. Consequently, the position signal is relatively less affected by electromagnetic noise.
