A salient pole synchronous motor is an a.c. rotating machine whose speed under steady state condition

is proportional to the frequency of the current in its armature. The magnetic field produced by the armature

currents rotates at the same speed as that produced by the field current on the rotor, which is rotating at the

synchronous speed. Synchronous machines are used in many industrial applications due to their high power

ratings and constant speed operation. The electrical and electromechanical behaviour of most synchronous

machines can be predicted from the equations that describe the three phase salient pole synchronous machine

[1]. These equations can be used directly to predict the performance of hydro and steam turbine synchronous

generators and synchronous motors. The rotor of synchronous machine is equipped with field winding and one

or more damper windings, which is magnetically unsymmetrical. Salient pole synchronous machines (SPSMs)

have salient pole or projecting poles with concentrated field windings. In synchronous motors, damper windings

act as rotor bars and help in self-starting of the motor. Salient pole synchronous machine is used to provide

independent control of mechanical torque and deliver electric power. It provides mechanical torque to the

rotating assembly and transmits electric power across an air gap to electric equipment mounted on the rotating

assembly. The rotor is then driven by external means producing a rotating magnetic field, which induces a three

phase voltage within the stator winding. Slip power recovery systems can provide both the mechanical and

electrical power transmission, but these are coupled and not independently controllable
