This invention discloses a multi-winding motor conductive ring structure, stator, and wind turbine generator. The motor conductive ring structure includes U, V, and W phase conductive ring groups. These three phase groups are arranged in rings from the outside inwards, with spacing between them, and are located on the same horizontal plane. Each phase group consists of 2N full-circle windings and 2N minor-arc windings. The virtual circle spacing formed by every two minor-arc windings is located between two full-circle windings. All conductive rings are located on a concentric circle, forming 4N sets of windings, evenly divided into two groups. Each group is individually connected to a corresponding converter. This invention divides multiple sets of windings into two equal parts. By combining full-circle windings and minor-arc windings, the winding current located within the two semicircles is introduced into the same converter, achieving redundancy design and uniform motor stress, avoiding vibration, noise, and other faults. It also reduces axial length and material usage, thereby reducing the unit's weight and manufacturing cost.
