ABSTRACT:
A coil winding and inserting machine suitable for winding stator coils of 3-phase multipolar motors. The machine has a plurality of independently liftable tooling blades and auxiliary plates. Three winding forms are formed simultaneously or in a predetermined sequence, each being constituted by two tooling blades and one selectively lifted auxiliary plate. Three flyers corresponding to the three winding forms are rotated around these winding forms to form coils of the first pole of respective phases. Then, the flyers make a 180.degree. indexing rotation and coils of the second pole are formed in the same manner as the coils of the first pole. After the winding of all coils, the coils are inserted into the stator core together with the wedges. Accordingly, it is possible to form the coils of u, v and w phases without cutting wires between two poles of respective phases, while ensuring an equal circumferential length of coils of all phases.
