Spool for a coil winding device and method of loading coils |
摘要 |
To provide a spool for a coil winding device capable of preventing poor insulation caused by a leakage of coil wires without initially inserted coil wires staying at the vicinity of slot openings. A spool for a coil winding device of this invention includes a plurality of coil winding surfaces increased stepwise in diameter from the bottom upward in a state where the spool is disposed on the coil winding device. The spool includes a front spool part and a rear spool part, which are placed at a distance from each other so that each turn of coil has a length corresponding to arbitrary lamination thickness of the stator core. The plurality of coil winding surfaces includes a coil winding surface corresponding to the outermost coil that is formed so that a portion in a radial pattern from the vicinity of a portion corresponding to a central axis of the stator core towards an opening of the slot in which each coil is loaded is extended at least to a position corresponding to a core back where the roots of the teeth outside the slot of the stator core are connected. |
