Fundamentals of Electric Energy,oidable that a study of electric energy would involve the varied aspects of electrical engineering. However, it is possible to divide (in a broad sense) electrical engineering into two major subareas: (1) communication and data technology, (2) energy conversion and control.

Induction Machines,airly simple torque—speed characteristics. For example, an air compressor motor is required to operate at a nominally constant speed and deliver a nominally constant torque. In such applications, a rugged design and the ability to operate directly off the ac network are very attractive.
