    Abstract: This application provides an oil-cooled motor, a powertrain, and a vehicle. The oil-cooled motor includes a rotating shaft and a first rotor iron core and a second rotor iron core that are sleeved on the rotating shaft and are adjacent to each other. A rotating shaft oil channel configured to communicate with a cooling system is disposed in the rotating shaft. M first oil channels that penetrate through two end faces of the first rotor iron core are disposed in the first rotor iron core. N second oil channels are disposed in the second rotor iron core. According to the oil-cooled motor provided in this application, a contact area between cooling oil and an interior of a rotor can be increased without affecting structural strength and magnetic conductivity of the rotor, so that cooling effect is improved.

    Abstract: A method of controlling a dual wound synchronous machine (DWSM) includes: determining virtual current commands based on a current command associated with each of two winding sets of the DWSM; determining virtual half-motor currents by applying a mathematical transformation on measured output currents; determining half-motor difference currents based on differences between the corresponding virtual current command and the virtual half-motor current; calculating forward path voltage commands based on the corresponding difference currents and using first and second gain factors; determining feedback voltage commands by applying third and fourth gain factors to the virtual half-motor currents; determining virtual final voltage commands based on the corresponding forward path and feedback voltage commands; determining final voltage commands by applying a second mathematical transformation to the virtual final voltage commands; commanding, based on the final voltage commands, inverters to apply corresponding voltages to the two winding sets and thereby generating the output currents.

    Abstract: In a core for a rotary electric machine, first end portions of back yoke portions are linked to second end portions of back yoke portions of adjacent core segments so as to be rotatable around pivot portions. Each of the core segments is configured by alternately laminating first core segment sheets and second core segment sheets. The pivot portions are constituted by interfitting protruding portions that are formed on the first core segment sheets. The core segments are displaceable relative to the adjacent core segments between a contracted position in which spacing between the magnetic pole tooth portions is contracted and an expanded position in which spacing between the magnetic pole tooth portions is expanded, when the core segment linked body is opened out rectilinearly.
