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.

Rotor-cooling structure of a drive motor

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is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots.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such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures.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.
