Robust Analysis of Dual Rotor Radial Flux Induction Motor Used for Industrial Application

Background: Dual Rotor Radial Flux Induction Motor (DRRFIM) is proposed in this study to improve the operating performance in a more concise way for several applications compared to the conventional Induction motor. Mathematical analyses are obtained from the modeling and analytical study of Double Rotor Induction Motors (DRIM) which are useful to determine the dynamical behavior of the motor in saturated and unsaturated conditions. Methods: In normal DRIM, the driving state flow equation is done by the state equations in q-d axis and Park's transformation. To develop and design such models, it is advised to use better optimization techniques adapted MATLAB2020/Simulink software for validation. Further, transient, and steady state performance of the DRRFIM is analyzed in the various scenarios with and without saturation in DRRFIM. Finding: The proposed research also compares conventional IM with optimization possibilities. In addition, a DRIM is being operated at different stages of load connectivity and the level of speed conditions is being further investigated in this work. The method proposed and implemented in this paper achieved the overall efficiency is 82% by optimizing the mention performance metrics like active and reactive power of machine, speed of motor and its torque performance. Novelty and Applications: Dynamical behavior of solving and optimizing the amplitude of unsaturated and saturated magnetic flux are of utmost importance. The study also presents a machine equipped with two rotors that uplift the performance of the induction motor. This machine has the potential to be utilized in industrially important applications as well as in vehicles that are driven by electricity.
