High speed maglev motor

The principle of a magnetic levitation motor is to use magnetic field force to suspend the rotor of the motor, achieving non-contact rotational motion, avoiding mechanical contact and friction, thereby improving the efficiency of the motor, reducing energy loss and noise pollution.
