Electric machines and drives are used in all aspects of our life wherever electricity is used. Nearly all the electricity is generated through electric generators and drives. Almost two‐thirds of this electricity is consumed by motor‐driven systems in the United States. There are opportunities for energy savings by making generators and motors more efficient. In addition, substantial energy savings can be obtained by converting motors that operate at essentially constant speed to variable speed drives, where the motor speed is efficiently controlled to match the system requirements, thus resulting in substantial system‐wide energy savings. There are emerging applications, such as electric vehicles, robotics, and drones, where precise speed and position control are essential. All these applications demand vector‐controlled ac drives that are discussed in this textbook.
