Aims |
|
Upon completion of this module students will understand the basic elements of Electromechanics. Students will be able to demonstrate the importance of these core topics in engineering applications and complete simple designs of their own. This module will provide students with a fundamental knowledge of the principles and construction of DC and AC machines, transformers and linear actuators . |
