摘要： In order to provide a modular arrangement, an inverter for an electric traction motor used to drive an automotive vehicle is positioned in proximity with the traction motor. The inverter is located within a compartment adjacent to one end of the electric traction motor and is cooled in a closed system by spraying a liquid coolant directly onto the inverter. The liquid coolant absorbs heat from the inverter and is cooled by a heat exchange arrangement comprising a reservoir with pipes carrying a second coolant from the radiator of the automotive vehicle. In a preferred embodiment, the coolant is collected from the inverter in an annular reservoir that is integral with the compartment containing the inverter. In accordance with one embodiment of the cooling arrangement, heat from the inverter vaporizes the liquid coolant by absorbing heat from the inverter during a phase change from a liquid to a vapor. The vaporized coolant is condensed by a circulating second coolant in pipes connected to the vehicle's radiator through a condenser that is preferably coaxial with the motor and the annular reservoir, which annular reservoir in the second embodiment collects overspray liquid coolant. In order to avoid degrading the inverter, the coolant is a dielectric fluid.
摘要翻译：为了提供模块化布置，用于驱动机动车辆的电动牵引电动机的逆变器位于牵引电动机附近。逆变器位于与电力牵引电动机的一端相邻的隔室内，并通过将液体冷却剂直接喷射到逆变器上而在封闭系统中冷却。液体冷却剂从逆变器吸收热量，并且通过热交换装置来冷却，所述热交换装置包括具有从机动车辆的散热器承载第二冷却剂的管道的储存器。在优选实施例中，冷却剂从与逆变器的隔室成一整体的环形容器中从逆变器收集。根据冷却装置的一个实施例，来自逆变器的热量在从液体到蒸汽的相变期间通过吸收来自逆变器的热量来蒸发液体冷却剂。蒸发的冷却剂通过连接到车辆散热器的管道中的循环第二冷却剂冷凝，该冷凝器优选地与电动机和环形储存器同轴，该第二实施例中的环形储存器收集过喷液体冷却剂。为了避免降低变频器，冷却剂是介质流体。

摘要： Methods and apparatus are provided for an axial electric motor. The apparatus comprises, a stator having coils thereon for producing a magnetic field, a rotor rotated by the magnetic field, and an output shaft coupled to the rotor. The rotor includes a magnetic and non-magnetic component. The non-magnetic component has a lower density than the magnetic component. One or both of the rotor components have apertures therein for ventilation and weight reduction. Permanent magnets are desirably mounted on the magnetic component of the rotor facing the stator and portions of the rotor behind the permanent magnets are hollowed out to be thinner than portions of the rotor between the permanent magnets. This reduces rotor weight without significantly affecting magnetic flux density in the rotor or motor torque.

摘要： A method of controlling an IPM machine having a salient rotor. Stator terminal signals are measured and rotated to obtain synchronous reference frame current signals. A rotor position is estimated based on an impedance generated using the rotor and included in the current signals. The estimated rotor position is used to control the machine. An alternator-starter system in which this method is used can provide high cranking torque and generation power over a wide speed range while providing operational efficiency.
