Design and Simulation of Dual Rotor Induction Motors for Core Loss Determination.

Dual rotor induction motors offer significant advantages in terms of torque density, efficiency, and power factor compared to conventional single rotor designs. However, the determination and minimization of core losses in such motors remain critical challenges, particularly as core losses directly impact overall motor performance and energy efficiency. This paper focuses on the design and simulation of dual rotor induction motors to accurately determine core losses under various operating conditions. Using advanced modeling techniques and simulation tools such as Finite Element Analysis (FEA) and the computational capacity of Ansys Maxwell 2D, the research had analyzed the effects of different design parameters, such as rotor geometry and material properties, on core losses. The goal is a developed optimized dual rotor induction motor design that minimizes core losses while maintaining high performance. The results showed that the core losses of the selected motor affected its performance at varied proportions. When the core losses were at 50%, the speed and output power of the motor was 92%. When the core losses were 100%, the motor overall performance dropped from 92% to 45%. This difference in performance index showed that when the core losses of three phase induction motor are not properly handled or eliminated, then the motor will not perform maximally to meet its expectations. These results have contributed to the development of more efficient dual rotor induction motors, with potential applications in industries requiring highperformance electric machines.
