Analytical design algorithm and FEM analysis of the dual-rotor Permanent Magnet Induction Machine

This paper presents an analytical design algorithm and a finite element method (FEM) analysis of a novel type of machine, the dual-rotor Permanent Magnet Induction Machine. The algorithm is based on the simplified Magnetic Equivalent Circuit (MEC) of the machine. After presenting the sizing procedure, the main results obtained via FEM computation are analyzed. Two possible configurations of the PM rotor are studied and compared in terms of developed electromagnetic torque, Joule and iron losses, and electromagnetic field capabilities.
