Functional Requirements
Modeling Tool for Permanent Magnet Motor
Motor Model Selection
The selection of the motor model will be based on complexity and
obtainable matching CAD files
Motor Simulation
Various modeling tools will be evaluated for accuracy, available
measurement parameters, usability and cost.
Following the selection of the tool and the model, the simulation of
the chosen motor will be executed with the software.
Stretch Goal: Motor Evaluation and Test Results
In order to validate the modeling software’s efficiency, torque, and
power output data for a permanent magnet motor, the motor must
be tested in a real-world situation.

Market Survey
A comparative analysis from a prospective engineering
graduate is not readily available to the client, software
companies, and research community.
The research and development style of this project
produces intellectual deliverables. As such, similar
projects are uncommon.
