A wire winding device which uses a large-sized supply bobbin, which has a large capacity and a large diameter, to highly precisely suppress a variation in tension which variation occurs when a coil is formed by winding a wire material at high speed with the wire material aligned with a winding frame. Rotation (the number of rotation, and timing) of the supply bobbin relative to rotation of the coil is controlled based on the difference between the amount of take-up of the wire material taken up on the winding frame side and the amount of pay-out of the wire material paid out from the supply bobbin, and the control is performed such that the amount of the take-up and the amount of the pay-out agree with each other every moment. This can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil and the supply bobbin.

Wire winding device

An apparatus for manufacturing a stator. On a split core of the stator, there are wound main conductors and two auxiliary conductors, which are thinner than but correspond to the main conductors. These main conductors are arrayed and wound in a plurality of layers, such that the main conductors of an upper layer are arranged in the valleys between the adjoining main conductors of a layer. For the main conductors of a first layer, the auxiliary conductors are arranged in a first space and a second space. For the main conductors of the second and subsequent layers, the auxiliary conductors are arranged in a third space, and the auxiliary conductors are arranged in a fourth space.
