Abstract :
A new type of electric machine with two free rotating rotors (Dual Mechanical Port) is investigated in this paper. Since this Dual Mechanical Port (DMP) machine has a Squirrel-Cage rotor, it is named as the SCDMP machine. First, the transient and steady state models of the SCDMP machine are derived based on its electromagnetic structure. Then, the equivalent circuits of the machine are proposed. The proposed machine models and equivalent circuits are verified by finite element method and simulation. The results show that the proposed models accurately represent the unique electromagnetic characteristics of the SCDMP machine.
