Shaft-embracing permanent magnet inter-shaft glued rotor structure of high-speed motor

摘要

The present invention relates to a shaft-embracing permanent magnet inter-shaft glued stator structure of a high-speed motor; the structure is a shaft-embracing permanent magnet integrated structure; the rotor structure comprises a permanent magnet (2), an output shaft (1) which is connected with one end of the permanent magnet (2) and embraces one part of the permanent magnet (2), and a rear shaft (4) which is respectively connected with the other end of the permanent magnet (2) and the output shaft (1), used for embracing the other part of the permanent magnet (2), and connected with the output shaft (1) to form a sealing mechanism of the permanent magnet (2). Compared with the prior art, the present invention has advantages of good electro-magnetic performance, high reliability, high productivity and good concentricity.
