Abstract:
On the basis of practical engineering experience, different stator slot structure optimisation solutions are designed for the problem of excessive magnetic induction intensity and stress concentration at the stator slot distortion point under the basic structure form of radial magnetic levitation bearing. The electromagnetic field analysis of the radial magnetic levitation bearing is completed with the aid of Ansoft Maxwell electromagnetic finite element analysis software, and the magnetic induction intensity distribution clouds are obtained. The simulation results show that a smooth transition fillet can effectively reduce the magnetic line concentration phenomenon at the stator slot inflection point.
