If the efficiency of these motors is improved, a large amount of energy can be saved. With the advent of power electronics it is now possible to control the torque and speed of electric motors precisely as needed, resulting in saving of energy. In this book various methods of control of electric motors are discussed. Sensorless control of motors requires the estimation of speed without actually measuring it. Similarly now the torque is controlled directly by the direct torque control method described in the book. Reluctance motors are also finding applications in many industries like consumer appliances, automobiles and defense. Special application of motors in dentistry is also described. The effect of human reaction on motor performance is also described. Muktar Ahmad Affiliacija editora India Part 1 Torque Control in Motors Used in Dentistry
