ELE 5403 - Specialty Electric Machines2 lecture hours 2 lab hours 3 credits
Course Description
This course focuses on the combination of electromechnical energy conversion, dynamic control theory, and power electronics, reinforcing theoretical concepts with simulations and physical implementations. (prereq: graduate standing)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Construct Permanent Magnet DC (PMDC) and Brushless DC (BLDC) machine dynamic electrical system models - armature resistance and inductance, and back emf
- Construct PMDC and BLDC machine dynamic mechanical systems using equivalent electrical model components - electromechanical torque production, friction and windage losses, and rotor inertia
- Construct dynamic mechanical load electrical model equivalent components representing mechanical systems - work load, mechanical inertia, and energy storage (spring) load
