[0002] A dual-turn brushless DC motor is a motor that uses two independent stator windings and a common rotor. It can achieve higher efficiency, power density and reliability compared to a single-turn brushless DC motor. The working principle of a dual-turn brushless DC motor is to control the AC current of the two stator windings through an electronic commutator so that it generates a synchronous rotating magnetic field with the permanent magnets on the rotor, thereby driving the motor to rotate. The advantages of a dual-turn brushless DC motor are that it can provide greater torque, lower noise, better heat dissipation and higher stability. The application areas of dual-turn brushless DC motors include industrial equipment, medical equipment, aerospace, new energy vehicles, etc.

[0003] Magnetizing equipment refers to equipment used to magnetize or fix magnets.
