Conceptual design and simulation for a double-rotor switched reluctance motor using parallel series windings

Abstract

In this paper, an interchangeable parallel-series winding approach is used to realize a compact machine-housing proposed for the double-rotor motor, based on switched reluctance principle. First, theoretical analyses are elaborated for the concept of the design, combining with the magnetic circuit analysis and given a demonstration by using this approach. Second, the basic mathematical model for the motor is introduced and by using finite element method (FEM), the magnetic field distribution of the motor is acquired and collect torque data, followed by the coupling effects analysis that shows the decoupled magnetic circuits for the two rotors. Finally, to simulate the real working condition, the multi-physical domain simulation is carried out, and high and low speeding operations are obtained. It suggested that the motor is capable of realizing high and low speeds for continuously variable transmission and is expected to be employed by electric vehicles (EVs) and Electric Vessel in the future.
