摘要： An electrical current sensing arrangement includes a busbar, a dielectric material containing therein a magnetic field sensor, and a ferromagnetic over-mold encapsulating a portion of the busbar and the dielectric material. The dielectric material is disposed against the busbar such that the magnetic field sensor is spaced away from the busbar and the ferromagnetic over-mold is not between the busbar and the magnetic field sensor.

摘要： A vehicle includes a traction motor having resonance frequency zones, an inverter including switches arranged to drive the traction motor, and a controller. The controller operates the switches only within specified sets of carrier frequencies such that noise side hands corresponding to the carrier frequencies fall outside the resonance frequency zones.

摘要： A system for a vehicle including an inverter electrically between a motor and traction battery, and a controller configured to operate the inverter at one of a predefined set of discrete frequencies selected according to rotor-torque-based probability weights corresponding to each of the discrete frequencies such that a probability that the inverter operates at the one changes as rotor torque changes.

摘要： A controller, while parameters are indicative of electromagnetic interference exceeding a predetermined value, generates voltage reference vectors or duty cycle commands such that differences between switching times of any two phases of an inverter are always greater than a threshold, and while the parameters are indicative of the electromagnetic interference being less than the predetermined value, generates the voltage reference vectors or duty cycle commands such that the differences are sometimes greater than the threshold and other times less than the threshold.

摘要： An electric machine includes a stator formed from a plurality of stacked laminations and defining a center bore and a rotor disposed within the center bore. The rotor is configured to output a rotational torque in response to an input current delivered to the stator. At least one of the stacked laminations of the stator includes a pattern of perforations disposed at a yoke portion of the stator to attenuate structure-bore transmission of vibration during operation of the electric machine.

摘要： Torque ripple produced by a traction motor of an electric vehicle when the motor produces torque from a motor current is compensated for by modifying operation of the motor according to a difference between an expected position of the motor to produce a desired torque from the current and the actual position of the motor when producing torque from the current.

摘要： A vehicle includes a ferromagnetic core having a winding, defining a gap, and configured to concentrate a net field in the gap. The vehicle also includes a controller programmed to flow a current in the winding such that an angle of the net field relative to a unipolar sensor in the gap is approximately zero and an intensity of the net field is at least twice that of a bi-directional field in the gap radiated from a conductor.
