Mathematical Modeling and Simulation of High-Speed Solid Rotor Induction Motor

Abstract

This study presents a comprehensive mathematical modeling and simulation of a high-speed solid rotor induction motor (HS-SRIM), focusing on the derivation of rotor impedance and the implementation of a dq-axis model for dynamic performance analysis. The research addresses the inherent challenges of solid rotor designs, including elevated electromagnetic losses and nonlinear material behavior, while highlighting their mechanical robustness and suitability for high-speed applications. Utilizing equivalent electrical circuits (EECs) and dq-axis transformations, the rotor impedance is analytically derived, incorporating factors such as edge effects, rotor saturation, and slip-dependent parameters. A MATLAB/Simulink model is developed to simulate the motor’s transient and steady-state behavior under varying loads, with and without edge effect corrections. Key results demonstrate the impact of edge effects on torque, current, speed, and power characteristics, revealing significant performance deviations between idealized and practical rotor configurations. The simulation validates the model’s accuracy in capturing high-speed dynamics at 400 Hz, though it underscores limitations in efficiency at elevated frequencies.
