Chapter 9. Principles of Electromechanical Energy Conversion
In this chapter, the methods for determining the induced emf in an electrical circuit and force/torque experienced by a movable part will be discussed. The general concept of electromechanical system modeling will also be illustrated by a singly excited rotating system.
Electro Mechanical Energy Conversion
To calculate the force or torque developed in machines, the principle of conservation of energy is used. For an electromechanical converter, dWe = dWf + dWm Let us assume that the movable part is held stationary. Since it is a lossless system, all the incremental energy input is stored as incremental eld energy.
