4. Project Plan: Functional Requirements
Selection of Modeling Software Tools
Based on availability and cost, four modeling software tools were selected for the project.
Model Design
A general permanent magnet motor will be designed to work with any modeling software and comply with client expectations.
Model Simulation
The model will be simulated with each software to analyze specific performance characteristics, such as flux linkage, back EMF, cogging torque, etc.
Software Evaluation
Each software will be evaluated for effectiveness in making implementation and purchase decisions in industry and research.
