Bearingless Permanent Magnet Synchronous Motor
The Bearingless Permanent Magnet Synchronous Motor (BPMSM) is able to function without bearings because it combines magnetic levitation with torque generation. Using this motor design, equipment can function faster, produce fewer sounds and frictional forces and be maintained less frequently while becoming more reliable. During accurate control and steady rotor suspension, BPMSMs depend on a combination of radial and levitation windings. They are used in precision equipment, tools for medicine and airplanes mostly because they are not too big and are very effective. The purpose of ongoing research is to optimize the actions, robustness and use of power in current drive systems by improving control and the design of their magnets.
