Abstract
The design and simulation of electric machines—such as Induction Machines (IMs) and Interior Permanent Magnet (IPM) motors—can be significantly optimized in terms of both time and cost by applying certain strategic techniques within Ansys Maxwell software. This paper presents a structured, step-by-step methodology for the laboratory-scale design and simulation of an IM, emphasizing best practices that streamline the modeling process. A transient solver is selected as the simulation type due to its suitability for capturing dynamic electromagnetic behavior, although it is computationally intensive. The study further explores the integration of U-shaped permanent magnets within the rotor yoke of an IPM motor, analyzing the impact of this unique configuration on machine performance. The design and simulation results confirm the feasibility of testing and evaluating various motor parameters under realistic conditions. Notably, although the U-shaped magnet configuration introduces geometric and computational complexity, its successful implementation suggests that alternative and potentially simpler structures can be simulated with relative ease. The approach outlined in this study provides a practical reference for engineers and researchers engaged in electric motor design, enabling more efficient modeling and analysis of complex machine architectures using commercial finite element analysis tools.
