Name of the equipment

Stator Frame

Function

It is the outer body of the machine made of cast iron, and it protects the inner parts of the machine.

Name of the equipment

Stator Core

Function

The stator core is made of silicon steel material. It is made from a number of stamps that are insulated from each other. Its function is to provide an easy path for the magnetic lines of force and accommodate the stator winding.

Name of the equipment

Stator Winding

Function

Slots are cut on the inner periphery of the stator core in which 3 phase or 1 phase winding is placed. Enameled copper is used as a winding material. The winding is star-connected. The winding of each phase is distributed over several slots. When the current flows in a distributed winding it produces an essentially sinusoidal space distribution of EMF.

Name of the equipment

Salient Pole Rotor

Function

The term salient means projecting. Thus, a salient pole rotor consists of poles projecting out from the surface of the rotor core. Since the rotor is subjected to changing magnetic fields, it is made of steel laminations to reduce eddy current losses. Poles of identical dimensions are assembled by stacking laminations to the required length. A salient pole synchronous machine has a non-uniform air gap. The air gap is minimized under the pole centers and it is maximum in between the poles.

Name of the equipment

Non- Salient Pole Rotor or Cylindrical Rotor

Function

Armature core includes a huge number of slots within its edge. The armature conductor is located in these slots. It provides the low-reluctance path toward the flux generated with field winding. The materials used in this core are permeability low-reluctance materials like iron otherwise cast. The lamination is used to decrease the loss because of the eddy current.

Name of the equipment

Brushes

Function

Brushes are made of carbon, and they slip over the slip rings. A DC supply is given to the brushes. Current flows from the brushes to the slip rings and then to the exciting windings.

Name of the equipment

Bearings

Function

Bearings are provided between the shaft and the outer stationary body to reduce the friction. They are made of high carbon steel.

Name of the equipment

Shaft

Function

The shaft is made of mild steel. Mechanical power is taken or given to the machine through the shaft.
