| Abstract: | A side-magnetism brake single-phase induction motor (SBSIM) for the application in electric tools was made,where a power-off brake is needed. The axial magnetic braking force was theoretically analyzed and calculated,which was first verified by the 3D finite element method(3D FEM). Then the flux density distribution in different air-gap positions with and with out load were analyzed,and the related parameters used in the theoretical expressions of braking force were given. |
