Active Magnetic Bearing
An Active Magnetic Bearing (AMB) is a type of bearing that uses magnetic fields to support a rotating shaft without physical contact. This technology allows for reduced friction and wear, leading to longer operational life and higher efficiency. AMBs are commonly used in applications where precision and reliability are critical, such as in turbomachinery and high-speed motors.
The system consists of electromagnets that adjust their strength in real-time to maintain the position of the shaft. Sensors monitor the shaft's position and provide feedback to a control system, which continuously adjusts the magnetic forces. This dynamic control enables the bearing to handle varying loads and speeds effectively.
