Stator coils are widely used in various unmanned aerial vehicles, fruit and vegetable machines, and other products. There are many types of stator windings for asynchronous motors, including single-phase, two-phase, and three-phase windings according to the number of phases. The stator coil is an important component that constitutes the magnetic flux circuit of the motor and fixes the stator coil. It is composed of punched sheets and various fasteners that are pressed together to form a whole.
