1. Concept: Magnetic Bearing (MagneticBearing) uses a magnetic effect to suspend the rotor in the air; there is no mechanical touch between the rotor and the stator.
2. Principle: The magnetic induction line and the magnetic floating line are straight; the axis core and the magnetic floating line are parallel; therefore, the component of the rotor is fixed on the working track; the axis core is almost undocked in the direction of the antimagnetic floating line; Form the entire rotor suspended; on a fixed working track.
3, strengths: compared with traditional ball bearings, oil bearings; magnetic bearings do not have mechanical touch; rotor can run to very high speed; with mechanical wear, low energy consumption, low noise, long life, no need for smooth, oil-free Contamination and other advantages; uniquely suitable for high-speed, vacuum, ultra-clean and other special environments.
4, magnetic levitation is only one kind of auxiliary function; it is not an independent bearing method; the detailed use has to cooperate with other bearing methods; such as magnetic suspension + ball bearing, magnetic suspension + oil bearing, magnetic suspension + vaporization bearing and so on.
