The basic use of a synchronous motor is “power factor correction” which means to increase the power factor of a system. Synchronous motors are used in voltage regulation; Synchronous motors are generally used for low speed, high power loads. Synchronous motors are generally used in air and gas compressors and vacuum pumps.

Synchronous Motor Working Principle Electrical motor in general is an electro-mechanical device that converts energy from electrical domain to mechanical domain. Based on the type of input we have classified it into single phase and 3 phase motors. Among 3 phase induction motors and synchronous motors are more widely used.
Synchronous Induction Motors There are three types of motors that can start and run as induction motors yet can lock into the supply frequency and run as synchronous motors as well. They are (1) the wound-rotor motor with dc exciter; (2) the permanent-magnet (PM) synchronous motor; (3) the reluctancesynchronous motor.
Synchronous motor works on the principle of the magnetic locking. When two unlike poles are brought near each other, if the magnets are strong, there exists a tremendous force of attraction between those two poles. In such condition the two magnets are said to be magnetically locked.
Synchronous Transmission. Synchronous transmission sends data as one long bit stream or block of data. There are no gaps in transmission; each bit is sent one after the other. The receiver counts the bits and reconstructs bytes. It is essential that timing is …
Synchronous Generator Basics. A synchronous generator is an ac generator in which the output is synchronized to the position of the rotor. The frequency of the voltage produced by the synchronous generator depends only on the speed at which its shaft is turned and the number of poles it has.This makes the synchronous generator very efficient for producing electrical power for utility companies ...

construction and principle of operation Permanent magnet synchronous machines generally have same operating and performance characteristics as synchronous machines. A permanent magnet machine can have a configuration almost identical to that of the conventional synchronous machines with absence of slip rings and a field winding.
Synchronous Generator Working Principle. The principle of operation of synchronous generator is electromagnetic induction. If there exits a relative motion between the flux and conductors, then an emf is induced in the conductors.
Let us see the application of this principle in case of synchronous motor. Consider a three phase synchronous motor, whose stator is wound for 2 poles. The two magnetic fields are produced in the synchronous motor by exciting both the windings, stator and rotor with three phase a.c. supply and d.c. supply respectively.
PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three.

Synchronous motor and induction motor are the most widely used types of AC motor. Construction of a synchronous motor is similar to an alternator (AC generator).A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.
