Magnetic damping rotational structure and magnetic damping generation method

Abstract

A magnetic damping rotational structure includes: a mounting base; a first annular magnetic bearing, fixed at the mounting base, where at least one side surface of the first annular magnetic bearing is uniformly arranged with first grooves, and a first magnetic protrusion is formed between adjacent two first grooves; and at least one second annular magnetic bearing, rotatably arranged at the mounting base, where the second annular magnetic bearing and the first annular magnetic bearing are coaxially arranged together, second grooves are uniformly arranged at a surface of one side of the second annular magnetic bearing facing the first magnetic protrusion, and a second magnetic protrusion is formed between adjacent two second grooves. A gap is formed between the first magnetic protrusion and the second magnetic protrusion, and the first magnetic protrusion and the second magnetic protrusion are arranged in one-to-one correspondence and generate attraction magnetic forces.
