IEM-IET Talk on Principle of Motor.
Synopsis of Talk:
DC motors have been known for their simplicity and ease of control especially in applications that are related to precision motion control. However, with the advent of digital signal processing technologies and power electronic converters, the use of dc motor drives has been replaced by ac-motor vector drives in many applications. Vector drives attempts to control an ac motor like a dc motor.
This talk will introduce the scalar drives and explain the basic principles/benefits of vector drives. Its aim is to provide some fundamental information for mechanical and electrical engineers who are involved in the operation and maintenance of vector drives.
