The focus of this book on the selection and application of electrical drives and control systems for electromechanical and mechatronics applications makes it uniquely useful for engineers in industry working with machines and drives. It also serves as a student text for courses on motors and drives, and engineering design courses, especially within mechanical engineering and mechatronics degree programs.

The criteria for motor-drive selection are explained, and the main types of drives available to drive machine tools and robots introduced. The author also provides a review of control systems and their application, including PLCs and network technologies. The coverage of machine tools and high-performance drives in smaller applications makes this a highly practical book focused on the needs of students and engineers working with electromechanical systems.

Key Features

  • An invaluable survey of electric drives and control systems for electromechanical and mechatronics applications
  • Essential reading for electrical and mechanical engineers using motors and drives
  • An ideal electric motors and drives text for university courses including mechatronics


A wide spectrum of users of electrical motors, drives and machines: electrical engineers, mechanical engineers, manufacturing engineers... Secondary market as a module text where courses focus on electromechanical systems and high performance drives.
