[0002] Motors are key equipment for converting electrical energy into mechanical energy. Motors mainly work through electromagnetic induction principle, that is, electric current generates force in a magnetic field, thereby realizing the conversion of electrical energy into mechanical energy. They are widely used in industrial production to drive conveyor belts, pumps, cooling fans, machine tools and robots, enabling production lines to operate efficiently.

[0003] As global concerns about energy crises and climate change continue to grow, improving energy efficiency has become an important goal for the industry. Traditional motors have lower efficiency when running at high speed due to mechanical losses and heat generation.
