Abstract:

A sidemagnetism brake singlephase inductionmotor (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 densty 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.

Key words: side-magnetism brake singlephase induction motor(SBSIM); braking force; axial magnetic field, FEM analysis
