Dynamic Simulation of a Novel Adjusting Speed Induction Machine with Inner and Outer Rotors

In this paper, a novel induction machine with inner and outer double rotors has been presented. The Double Rotors Induction Machine (DRIM) has the advantages of slow leakage inductance and high operation performance. This paper describes simply its structure and special windings. The electric-magnetic relationship and mathematic model of the DRIM have been built in actual coordinate, and the simulating program in MATLAB language has also been finished. Moreover, the simulation results and its analysis are given in this paper. The research shows that the operation characteristic of the DRIM is similar to the conventional induction machine.
