Permanent Magnet Motor Modeling Kaila Krieser, EE Dan Montgomery, EE Craig Christofferson, EE Mark Wisted, EE Dr. Mani Mina, Advisor Dr. David Jiles, Advisor Dave Sowders, Kansas City Plant Client Problem Objective The team will select, use and assess an electromagnetic modeling software tool to simulate Permanent Magnet Motor operation in variable magnet and environmental configurations. Key Steps: 1. 2. 3. 4. Selection of Tool Selection of Model Modeling Execution Experimental Validation Conceptual Sketch Design Motors Industry Other Electromagnetic Modeling Problems Modeling Software Tool Evaluation Research Magnet Material Experiments System Block Diagram Research • PMM Function • PMM Modeling Fundamentals • Performance Characteristics • Magnetic Material Characteristics Selection • Software • PMM CAD File Software Evaluation • Accuracy (Stretch Goal: Physical Testing • Cost • Usability • Magnet Materials • Performance Characteristics Simulation • FEMM • Opera-2D • ANSYS EM • MagNet 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.
