A Passive Magnetic Bearing is a type of bearing that uses magnetic forces to support a rotating shaft without physical contact. This design minimizes friction and wear, leading to longer lifespan and reduced maintenance. The magnetic forces are generated by permanent magnets, which create a stable levitation effect, allowing the shaft to float in the air. These bearings are commonly used in applications where precision and reliability are crucial, such as in turbines, electric motors, and high-speed machinery. By eliminating the need for lubrication, passive magnetic bearings also contribute to cleaner and more efficient operation in various industrial settings.
