Functional Requirements Modeling Tool for Permanent Magnet Motor
Various modeling tools will be evaluated for accuracy, available measurement parameters, usability and cost.
Motor Model Selection The selection of the motor model will be based on
complexity and obtainable matching CAD files Motor Simulation
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.
