A synchronous machine is an ac rotating machine whose speed under steady state condition is proportional to the frequency of the current in its armature. The magnetic field created by the armature currents rotates at the same speed as that created by the field current on the rotor, which is rotating at the synchronous speed, and a steady torque results.

Micro-machines are electric machines with parts the size of red blood cells, and find many applications in medicine. Electric motors are broadly classified into two different categories: DC (Direct Current) and AC … Similarly when the machine is used as a DC motor, the commutator switches the DC supply voltage to alternate arms of the coil each half cycle in order to achieve unidirectional rotation. Thus in all wound rotor DC machines, both motors and generators, the current in the rotor windings is AC and it is the commutator which enables the corresponding DC input or output.

induction machines, are the most widely used type of electric machine. The basic operation of the ac machine is similar in concept to the dc machine where the A synchronous machine is an ac rotating machine whose speed under steady state condition is proportional to the frequency of the current in its armature. The magnetic field created by the armature currents rotates at the same speed as that created by the field current on the rotor, which is rotating at the synchronous speed, and a steady torque results. Synchronous machines are commonly used
