This module demonstrates to the student where the basic principles of electro-magnetism translate into industrial actuators such as DC motors, AC motors and Stepper motors. This module will apply knowledge of the National Rules for Electrical Installations to allow the graduate to work safely with electrical panels. Finally the module aims to equip students with the ability to read and understand drawings of electrical installations and hence communicate with other professional engineers.
