ES2C6-15 Electromechanical System Design
The module aims to develop an understanding of electrical power generation, transmission, distribution and consumption and of how integrated engineering systems with energy conversion stages operate. It also aims to an understanding of the underpinning science behind energy conversion in electromechanical systems and instil the fundamental engineering principles and mathematical techniques of electromechanical power conversion. The module aims to show applications of instrumentation and measurement in integrated electromechanical engineering systems, apply the principles of engineering control and feedback and design an electromechanical system with motors, actuators, sensors, control, etc.
