Subject Title
Electrical Machines

Subject Description

This course covers the basics of electrical motors operation and principles of motor control technologies.

The first part of the course covers general knowledge about AC and DC motors. General motor/machine operation is described.  Different types of braking and loads on a motor are addressed, as well as questions of improving motor efficiency and power.  In the second part of the course different control techniques are discussed, including different methods of starting a motor, controlling voltage and frequency and the role of different sensors in relation to motor operation.

Technical documentation such as data sheets and specifications of mechanical elements of the complete electrical motors drive-train will also be covered.  By understanding the interworking of the complete system, students will learn and apply troubleshooting strategies to identify, localize and (where possible) correct malfunctions.  Preventive maintenance as well as safety issues within the motor drive-train system will be discussed.

Credit Status
One subject credit in the Electronic Engineering Technology Programs
