摘要： An embodiment rotor includes a stacked core including stacked lamination sheets. The lamination sheets include lamination segments arranged in a circle, the stacked core has an upper layer lamination segment coupled to a lower layer lamination segment with a phase difference therebetween of a first angle with respect to a center of the stacked core, the stacked lamination segments have keys arranged in a straight line on an inner surface of the stacked core so that the keys are inserted into a key way disposed in a motor shaft in an axial direction, the lamination segments have a substantially identical shape and are arranged with an interval of a second angle with respect to a center of the rotor thus having a substantially identical pattern, and the lamination segments include upper and lower layer coupling portions repeatedly disposed at intervals of the second angle in a circumferential direction.

摘要： A rotor-cooling structure is for a drive motor including an inner shaft, a rotor shaft surrounding the inner shaft, a rotor connected to the rotor shaft, and a stator disposed to be spaced apart from the rotor. The rotor-cooling structure includes: a first flow passage formed in the inner shaft; a second flow passage formed in the rotor shaft to receive oil through the first flow passage; a third flow passage formed in a plate disposed at an end of a rotor core, constituting the rotor, to be connected to the second flow passage; and a fourth flow passage formed to be connected to the third flow passage and to penetrate the rotor core in the direction in which core plates constituting the rotor core are stacked.

摘要： A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.

摘要： A cooling-channel integrated motor housing includes a motor housing, a plurality of stator cores press-fitted into the motor housing, and a cooling pipe inserted into the motor housing and disposed in a circumferential direction of a circle along which the stator cores are arranged. The 1cooling pipe is disposed to overlap with the stator cores in a direction perpendicular to a direction in which a rotating shaft of a motor extends.
