Magnetic Bearing and its New Applications

Magnetic bearing is a high-performance mechatronic bearing, which can suspend parts in space stably using magnetic force. Its characteristics such as high speed, high precision, and low power consumption and so on make it valuable to research and widely to apply in the future. The paper summarized the working principle of magnetic bearing and its characteristics, research and application status. Based on these, it introduced the new application such as used for vibration reduction, dynamic absorber and in mining electromechanical device in engineering field, so as to increase efficiency and save more energy.
