PURPOSE: A stator coil is provided to simplify a forming process, improve workability and achieve an exact insertion by forming a linear coil into a sine wave by a pusher, winding the coil on a winding tool and inserting the coil to a stator core. CONSTITUTION: A slot(11) is formed on an inner peripheral surface of a stator core(1). A barrier(13) of the slot has a predetermined gradient. A latch part(14) which is an entrance of the slot is formed by shaping the barrier like T. Unevenness parts of the winding tool(7) are facing each other each position where three slots of the stator core(1) exist. Accordingly, the entrance of the stator core slot and an insert part of the winding tool get to face each other. A stator pusher(4) pushes the coil in an inner circumferential direction of the winding tool and inserts the coil(5) to the inside of the slot(11) of the stator core. For the purpose of protecting the inserted coil, a wedge is inserted by using a wedge pusher on a lower part surface of the stator core(1). Therefore, when the entrance of the stator core(1) is clogged, the barrier(13) of the stator slot is swaged so as to form the latch part.
