摘要： A vehicle cooling arrangement includes a first electric machine with a drive output shaft and a first rotor mounted to rotate about a rotation axis and extending axially around the rotation axis. A first stator surrounds the first rotor peripherally. A second electric machine is mounted axially close to the first electric machine and has a second rotor mounted to rotate about the rotation axis and the drive output shaft. A second stator surrounds the second rotor peripherally. A common housing forms a casing for the first and second electric machines and the drive output shaft extends axially through the housing. The first and second electric machines form a coolant circuit having at least one coolant line arranged to cool the first and second rotors and a second coolant line parallel to the first coolant line and arranged to separately cool the first and second stators.

摘要： According to an embodiment of the present disclosure, provided is a high-output, high-torque in-wheel motor having a power line-taken-out structure. According to an embodiment of the present disclosure, the in-wheel motor includes a circular rim; a shaft connected to the rim through a center of the rim; a motor assembly including a stator connected to the shaft in the rim and a rotor surrounding the stator and rotated about the stator; a cover coupled to an opening of the rim to block the motor assembly from an outside of the rim; and a bearing contacting and configured to support the shaft. The shaft includes a first shaft body passing through a center of each of the rim and the cover and extending outward; and a second shaft body having a larger diameter than a diameter of the first shaft body and disposed between the stator and the bearing. A power line for supplying power to the motor assembly is inserted in a radial direction of the second shaft body between the stator and the bearing and is taken out in a longitudinal direction of the second shaft body. According to an embodiment of the present disclosure, even when a diameter of the power line is increased to achieve the high-output, high torque performance of the in-wheel motor, structural rigidity of the shaft may not be degraded.

摘要： A coolant supply system for an electric vehicle axle drive having an electric machine, in the electric machine housing of which a stator interacts with a rotor. The electric machine outputs to at least one vehicle wheel of the vehicle axle via a transmission arrangement. A coolant separator is arranged in the electric machine housing, which divides the interior of the electric machine housing into a radially outer stator chamber, in which the stator with its stator windings is arranged, and into a radially inner rotor chamber, which is separated therefrom in a largely fluid-tight manner and in which the rotor is arranged.

摘要： An in-wheel motor in which a torque will not be applied excessively to a rotor and a wheel, and in which an axial length is reduced. In the in-wheel motor, a rotor is arranged around the stator, and torque is transmitted between a drive member rotated integrally with the rotor and a driven member rotated integrally with a wheel through a transmission member. The transmission member is adapted to allow the drive member and the driven member to rotate relatively to each other when an extraordinary torque is applied to the drive member or the driven member, thereby restricting the torque transmitted between the drive member and the driven member to a predetermined magnitude.

摘要： An electric machine configured to generate and transfer drive torque to a driveline for propulsion of an electric vehicle includes a gearbox assembly, an electric motor having a rotor and a stator having end windings, and a thermal management system. The thermal management system includes a first end plate disposed at an axial end of the rotor. The first end plate has a central hub and an overhang. The overhang includes an outwardly extending radial rim and a lip. The radial rim includes an outer surface, an inner surface, and at least two passages defined therethrough. The first end plate facilitates cooling of the electric motor by directing fluid (i) off of the outer surface of the radial rim and onto an inner diameter of the end windings, and (ii) through the at least two passages and onto the inner diameter of the end windings.

摘要： A synchronous electric motor includes a rotor and a stator. The stator includes an armature and coils. The armature includes a yoke and teeth. The teeth define recesses. The coils are mounted in the recesses of the armature. The stator is wound by insertion. Each coil is formed from a wire outside the stator, so that the coils are subsequently inserted into the recesses, through wire passages of the recesses according to a direction radial to a central axis of the stator. Furthermore, a ratio of a surface area of each recess to a thickness of the yoke is between 5 mm and 10 mm, the surface area of each recess being measured in a plane perpendicular to the central axis of the stator.
