Three phase squirrel-cage induction motor optimization using finit element method
This paper presents the results of an optimization process on a three phase squirrel-cage induction motor designed for mining applications. In order to achieve the imposed working characteristics (limited start-up current and convenient torque values), deep rotor bars and double cage solutions have been considered and analyzed. For this aim, the finite element method (FEM) has been used. The obtained simulation results were compared in order to find the most suitable solution for the specified application, considering the influence of each design upon the motor performance.
