[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Its main function is to generate a driving torque and serve as a power source for electrical appliances or various machines. During the manufacturing process of a motor, first, an automatic winding device is used to wind a wire around a mold that matches the stator or rotor of the motor to form a coil, and then the coil is installed on the stator or rotor of the motor.
