[0002] The stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate output current.

[0003] For example, the announcement number is CN107332366A, and the name of the Chinese authorized patent is (fastening structure of split stator core), which includes: several fan-shaped core units connected in series to form a circular stator core, grooves are provided on the upper parts of both sides of the fan-shaped core units, tenons and tenons are provided on the lower parts of both sides of the fan-shaped core units, and two adjacent fan-shaped core units are connected by tenons and tenons embedded in each other, and the grooves of two adjacent fan-shaped core units are butt-jointed to form a wire slot for winding the stator coil, and the fan-shaped core unit is composed of several punching sheets stacked together, which is characterized in that columnar notches are provided on the joint surfaces of the tenons and tenons, and the columnar notches of the tenons and the tenons are connected to form a columnar hole, and a wedge is inserted in the columnar hole. Compared with the existing technology, the present invention has the advantages of easy assembly, and after assembly, the split stator cores can be connected and fastened to each other, thereby avoiding the unreliable operation of the motor due to the loosening of the split core.

[0004] However, the existing split-type petal-type stator is not firmly connected when in use and has the problem of looseness; therefore, it does not meet the existing needs. In this regard, we propose a petal-type wind turbine stator coil winding mold. Utility Model Content
