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is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots.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such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures.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