Bobbin and coil mounting method of the winding device

It no initial insertion coil wire stays in the vicinity of the slot opening, to provide a winding frame of the winding apparatus which can solve the insulation failure of the coil wire leakage. Winding frame of the winding apparatus according to the present invention, with respect to the arrangement when installed on the winding device comprises a plurality of coil turns stages are stepwise diameter from each bottom to the top, any stator and a front winding frame and the rear bobbin being spaced in order to shape the length of the coil different in correspondence with core lamination thickness, coil Makidan corresponding to the coil of the outermost periphery of the front winding frame, stator extending from the vicinity of corresponding to the core center axis radial to become part in a direction along the opening of the slot which each coil is inserted to a position corresponding to the core back which connects the outer tooth root of at least the stator core slot and it has a configuration.
