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.

Using magnetic levitation bearing technology to achieve high speed and maintenance free operation of the motor, solving users' high-speed demand, maintenance, and energy-saving issues at the system level; The standard series motors can be applied in various industries such as air compressors, blowers, ORC power generation, expanders, high-speed electric spindles, etc.
