Industrial motor drives is a new and growing area in electrical engineering. Recent advances in high power devices permit the control and flow of electric energy efficiently. The digital nature of power switching devices makes the control of electric power switching circuits convenient with microcomputer control. Motor drives have wide spread applications in today’s industry such as machine tools, elevators, cranes, transportation, etc.

This introductory course is intended to familiarize the engineering students with major aspects of motor drives. DC drives fed by controlled rectifiers and choppers, squirrel cage induction motor drives controlled by ac voltage controllers, voltage source inverters, current source inverters, PWM inverters, slip power controlled wound rotor induction motor drives will be covered.

A new laboratory concept, the Actual/virtual lab has been developed for this course. This lab will familiarize the students with both hands on experimentation with motor drives on actual and virtual test beds.
