Abstract: A current sensor includes an induction coil, a Hall sensor, and a calibration coil loaded by a generator continuously with a calibration current of defined frequency ?cal. A first evaluation circuit is loaded with the induction signal. A second evaluation circuit, whose input receives the Hall signal, includes a low-pass filter. A third evaluation circuit evaluates a part of the Hall signal that is attributed to the calibration current and uses it for defining a parameter of the second evaluation circuit. A fourth evaluation circuit generates an output signal that represents the current magnitude and is the sum of the output signal of the first evaluation circuit and the output signal of the second evaluation circuit minus the part of the output signal of the second evaluation circuit which is attributed to the calibration current.

Abstract: A vehicular device having a driven device and an electric motor coupled to and driving the driven device. The electric motor includes a rotor and a plurality of slots in the rotor. The rotor has a plurality of magnets. The plurality of slots includes a first slot associated with a corresponding one of the plurality of magnets thereby defining a first magnet. The first slot has a boundary that is partially defined by the first magnet. The first slot contains a fluid in direct contact with the first magnet.

Abstract: An insulation resistance detection system for use with a vehicle having a chassis. The system includes an electrical power source, an electrical system, and a detection circuit. The electrical system is electrically isolated from the chassis. The detection circuit is powered by the power source. The detection circuit includes a resistor electrically connected to the chassis. The detection circuit measures the voltage across the resistor to thereby determine insulation resistance between the electrical system and the chassis.

Abstract: An electrical circuit assembly includes an electrical circuit substrate having a first side; a heat sink including a metal base plate having a first side and a second side, and a plurality of fins extending from the second side; and a thermally conductive and electrically insulating adhesive directly interconnecting at least a portion of the first side of the electrical circuit substrate with the first side of the base plate.
