Abstract

The present invention relates to a stator coil winding machine including: a stator transfer unit adapted to transfer a linear type stator having a plurality of stator cores in directions of X and Y axes; a winding guide unit adapted to guide the transferred stator to coil winding; a winding unit adapted to wind a coil on the stator; a tension adjusting unit adapted to adjust tension on the coil being wound on the stator; and a controller adapted to control operations of the stator transfer unit, the winding guide unit, and the winding unit to allow the coil to be wound on the stator by means of three-phase Y connection, based on a previously set winding sequence.
