ABSTRACT
As shown in Chapter 2, the slots of the stator and rotor cores of induction machines (IMs) are filled with electric conductors, insulated (in the stator) from cores, and connected in a certain way. This ensemble constitutes the windings. The primary (or the stator) slots contain a polyphase (three- or two-phase) A.C. winding. The rotor may have either a three- or two-phase winding or a squirrel cage. Here we will discuss the polyphase windings.
