The Rotors and Stators

The stator, which is also known as armature, is the fixed part of the motor, housed around the rotor so that it rotates inside it, which is also composed of a package of blades of a ferromagnetic material wrapped in a set of windings spread throughout their circumference and deposited in grooves.

The stator windings are fed by a three-phase alternating voltage system and circulate throughout the stator, the electric energy generated, since both the voltage and the current flowing are very high in relation to the field or rotor, which has only cause a magnetic field to activate the machine. In the case of certain synchronous machines, the rotor can be composed of a permanent magnet in place of an electromagnet, being called a permanent magnet synchronous machine.

The voltage applied to the rotor winding is continuous, causing the current to be withstand by the winding of the rotor, since the rotor can have two or more windings, always in even number and all connected in series , and that each winding becomes responsible for the production of one of the poles of the electromagnet.
