Magnetic bearings are devices that support a rotating shaft using magnetic fields instead of traditional mechanical contact. This technology eliminates friction, which reduces wear and tear, leading to longer operational life and lower maintenance costs. They are commonly used in applications like turbines, compressors, and electric motors. These bearings operate by creating a magnetic field that levitates the shaft, allowing it to spin freely. This levitation can be achieved using either permanent magnets or electromagnets. Magnetic bearings are particularly beneficial in high-speed applications, where traditional bearings may fail due to heat and friction.
