High-speed permanent magnet motor rotor including axial-forced magnetic-conductive jacket

The invention discloses a high-speed permanent magnet motor including an axial-forced magnetic-conductive jacket. The high-speed permanent magnet motor comprises a rotating shaft, a front hooped plateand a back hooped plate are arranged on an axial direction of the rotating shaft; two ends of a plurality of magnetic-conductive jacket plate plates are fixedly connected with the front hooped plateand the back hooped plate to form electric insulation; a rotor iron core is arranged between the front hooped plate and the back hooped plate and fixedly connected with the rotating shaft; the permanent magnet is fixedly arranged between the roto iron core and each magnetic conductive jacket plate; the amount of each of the magnetic conductive jacket plate and the permanent magnet is same as the pole number of the rotor; each of the front hooped plate and the back hooped plate is made from non-magnetic conductive material, a first clearance is formed between the adjacent magnetic conductive jacket plates, a second clea
