Preface The industrial brushless servomotor has developed through a remarkable combination of mechanical, electrical, power electronic and microelectronic technologies, and both the operation and application of the motor rely on many interdependent factors. I have tried to cover the fundamentals of the subject in a logical manner, taking a step-by-step approach, describing first the construction of the brushless machine itself and how it works, second, how the current is supplied, third, how the motor behaves when it is loaded and finally how it is rated and selected for a particular duty. The book covers the important motor and load characteristics which.
