A winding machine includes flyersrotated around a flyer rotation axis AXf orthogonal to the axis AXs of a rotorconstituting a work while at the same time winding wireson coreof rotor. Rotoris set in the winding machine in such a position that the center position of corein the direction along rotor axis AXs and flyer rotation axis AXf are displaced from each other.

Winding machine for rotor and method of fabricating rotor

The present invention generally relates to a coil insertion device for inserting a stator coil into a slot defined within a stator core of an electric rotary machine and to an improvement in a mechanism for inserting a stator coil into a slot. The coil insertion device includes a plurality of clamping guides moveable along the inner peripheries of the stator core and the base body and circumferentially arranged in a regularly spaced relationship, a plurality of coil clampers arranged radially inward and in opposition to the clamping guides for clamping a prewound stator coil in an aligned condition with the clamping guides and for shifting upward according to an upward movement of the clamping guide to draw the stator coil into the slots at a given angle of tilt, and a plurality of blades moveable along the inner periphery of the base body, the blades being formed in an essentially identical configuration and having essentially the same arrangement as the clamping guides 52, thereby permitting a stripper extending therethrough to push the stator coil into the slot by an upward movement after an insertion by the coil clampers.

Coil insertion device

A tension apparatus for imposing a predetermined tension on a wire-like member which is used for a stator or a alternator. First and second rollers are rotatably supported on a supporting means in such a manner that a space between the first roller and the second roller is smaller than a diameter of the wire-like member. When the wire-like member is passed through a space between a first roller and a second roller, the wire-like member is deformed, and after all, a predetermined tension is imposed on the wire-like member. The tension of the wire-like member can be changed in accordance with the space between the first roller and the second roller.
