Abstract

Abstract: For the high-speed permanent magnet motor with the surface-mounted structure, the magnet cannot bear the centrifugal force due to the high-speed rotation and is easy to break. Via the tension winding technology, the carbon fiber reinforced plastic (CFRP) rotor sheath can effectively guarantee the safe and steady operation of the rotor. By the ANSYS Workbench software, finite element analysis was conducted on the tension winding of the CFRP rotor sheath for a surface-mounted high-speed permanent magnet motor. The results show that the finite element model can accurately simulate the stress field of the sheath during the winding process. Besides, under the predetermined winding stress on the fiber, the magnet and the shaft can keep the tight contact during the running process of the rotor, with their stress level maintained below the ultimate limit.
