Abstract :
The mechanical deformations and stresses have been analyzed by the finite element method (FEM) in 3 dimensions on the rotor bars of a small squirrel cage induction motor. We considered the magnetic forces and the centrifugal forces as sources which provoked the deformations and stresses on the rotor bars. The mechanical calculations have been performed after doing the electromagnetic finite element modeling on the motor in steady state with various slip conditions
