Catalog Data & Credits (Recitation-Lab-Total)
EE420 Electric Machines and Drives (3-2-4): The course includes an introduction to magnetic circuits and electromechanical energy conversion principles. Building on these topics, the basic operation, analysis, modeling and design of transformers, DC machines, induction machines, and synchronous machines is then presented. The simulation and power electronic control of DC and AC machines are considered. The output waveforms of a synchronous machine/three-phase rectifier, as part of a DC distribution system, are investigated. The course utilizes both simulation exercises and extensive laboratory hardware exercises to reinforce theory and validate derived models.
Pre-requisites
EE320 Introduction to Electrical Engineering II
Course Objectives
- Explain the operating principles of transformers, relays, and DC/induction/synchronous machines. Identify these principles in new-to-the-Navy technologies currently being introduced to the Fleet.
- Analyze and derive machinery models using magnetic equivalent circuit concepts.
- Solve steady-state machinery models using equivalent circuits, torque, and power relationships.
- Execute hardware laboratory experiments to characterize machinery performance and determine model parameters.
- Design and execute digital Simulink simulations of machinery, power converters, and control systems.
- Explain the operation and control of AC machine power converters and identify them in new-to-the-Navy technologies currently being introduced to the Fleet.
- Analyze, design and characterize the operation of AC machine speed control.
- Use MATLAB to graphically document laboratory work and solve more complicated steady-state problems.
