Claim 0:
1. A connection structure of a stator of a drive motor, the connection structure configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots, wherein:
the coils are wound in the slots to form first-type structures and second-type structures configured such that a withdrawal direction of three-phase (U-, W- and V-phase) withdrawal lines withdrawn from the slots of the first-type structures and a withdrawal direction of N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to a withdrawal direction of three-phase (U-, W- and V-phase) withdrawal lines withdrawn from the slots of the second-type structures and a withdrawal direction of N-phase withdrawal lines withdrawn from the slots of the second-type structures; and
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.
