The hollow cup motor breaks through the traditional rotor structure of electric motors in terms of structure, using a coreless rotor, also known as a hollow cup rotor. This novel rotor structure completely eliminates the electrical energy loss caused by eddy currents formed by the iron core, while significantly reducing its weight and rotational inertia, thereby reducing the mechanical energy loss of the rotor itself. Due to the structural changes of the rotor, the operating characteristics of the electric motor have been greatly improved. It not only has outstanding energy-saving features, but more importantly, it has control and drag characteristics that iron core motors cannot achieve.
