Abstract: An oil transfer assembly supplies oil into a moving, rotating tube extending along an axis. The assembly is provided with a support plate transversal to the axis and a sleeve, which is angularly fixed with respect to the support plate, it is configured to be coupled in a sliding and watertight way to a terminal section of the inlet of said tube and has at least one chamber for transferring oil into said terminal section of the inlet. The assembly is also equipped with at least two tubular bodies, which project axially from the support plate, define between them an annular channel communicating with the chamber and join the sleeve to the support plate in a watertight manner and with clearances so as to leave freedom of orientation of the sleeve around any direction orthogonal to the axis.

Abstract: A method for designing a rotor structure of a synchronous reluctance electric machine, wherein the rotor structure has an annular arrangement about a central opening designed to be engaged by a rotation shaft, and provided with a plurality of magnetic portions, a plurality of electromagnetic flux barriers interposed between the magnetic portions, and radial connecting elements, for the mechanical connection between radially adjacent magnetic portions, the electromagnetic flux barriers defining at least one maximum magnetic reluctance path along a maximum reluctance axis and a minimum reluctance path along a minimum reluctance axis. The method envisages defining the arrangement the electromagnetic flux barriers and/or the radial connecting elements so as to jointly optimise electromagnetic performance of the synchronous reluctance electric machine and mechanical resistance properties, in particular the resistance to centrifugal forces due to rotation about the rotation shaft.

Abstract: Input is received. A conformance is determined. When conformance is determined, a raw torque is measured from a torque sensor at an engine; the raw torque is calibrated using the torque sensor parameters to produce a calibrated torque value, non-torque parameters associated with the engine are measured and the non-torque parameters are applied to a lookup structure to obtain an expected torque value. A separation of the calibrated torque value and the expected torque value is determined and based upon the separation, an operation of the torque sensor is controlled.
