摘要： Methods and systems are provided for modeling temperature characteristics of components in a system such as a power module for a hybrid or electric vehicle. A power dissipation value is calculated for each of the components in the system. A first filter is applied to the power dissipation value associated with a selected component to determine its estimated temperature. For each of the neighboring components located adjacent to the selected component, a cross-coupling temperature is estimated by applying other filters to each of the power dissipation values for the neighboring components. The estimated temperature of the selected component and the estimated cross-coupling temperatures for each of the neighboring components can then be added to thereby estimate the operating temperature for the selected component. Further, the operation of the system may be adjusted if the operating temperature determined for the selected component exceeds a threshold value.

摘要： A coaxial stack of laminations for a stator of an electrical machine uses laminations that are substantially identical and in direct abutment with one another. Each of the laminations has an outer periphery and an inner periphery with the outer periphery being defined by an array of outwardly projecting pins and the inner periphery being defined by an array of inwardly projecting teeth. The outwardly projecting pins cooperate with a jacket surrounding the stack to provide a cooling space through which cooling liquid flows while the teeth provide spaces therebetween for receiving for receiving stator windings. The number of pins (npin) is proportional to the number of teeth (nth) according to the relationship (2K+1)/(2Kth) times the number of teeth (nth), where K is a selected integer number and Kth is the number of teeth past which each lamination is rotated with respect to adjacent laminations so that spaces between the teeth of adjacent laminations are aligned.

摘要： A rotor for an interior permanent magnet machine has a rotor body having an output shaft and a first cavity filled with magnetic material. Second cavities are disposed inboard of the first cavities and are not filled with magnetic material. Non-magnetic rods extend through the second cavities and protrude beyond end faces of the rotor body. The rods are press-fit in blind bores formed in non-magnetic end plates disposed adjacent the end faces of the rotor body. Shrink disks are shrunk around projecting ends of the output shaft in abutting relation with the end plates. In order to prevent induced voltage from generating current in the cage formed by the rods and end plates, an oxide layer is disposed between the rods and blind bores in the end plates.

摘要： Systems and methods are provided for an automotive drive system using an absolute position sensor for field-oriented control of an induction motor. An automotive drive system comprises an induction motor having a rotor, and a position sensor coupled to the induction motor. The position sensor is configured to sense an absolute angular position of the rotor. A processor may be coupled to the position sensor and configured to determine a relative angular position of the rotor based on a difference between the absolute angular position and an initial angular position obtained when the induction motor is started. A controller may be coupled to the induction motor and the processor and configured to provide field-oriented control of the induction motor based on the relative angular position of the rotor.
