What is the difference between synchronous motor and a synchronous generator?

In this psot we will discuss Difference between Synchronous Motor & Synchronous Generator. The motor is a device that is used to transform electrical energy into mechanical energy and generator is used to transform mechanical energy into electrical energy.

What is the working and principle of synchronous generator?

An alternator or synchronous generator works on the principle of electromagnetic induction, i.e., when the flux linking a conductor changes, an EMF is induced in the conductor. When the armature winding of alternator subjected to the rotating magnetic field, the voltage will be generated in the armature winding.

What is the working principle of synchronous motor?

The principle of operation of a synchronous motor can be understood by considering the stator windings to be connected to a three-phase alternating-current supply. The effect of the stator current is to establish a magnetic field rotating at 120 f/p revolutions per minute for a frequency of f hertz and for p poles.

What is the difference between alternator and synchronous generator?

An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. Generators are considered less efficient.

What is difference between synchronous generator and alternator?

Both the Alternators and generators are used to generate electricity. Alternators are also known as synchronous generator. Both perform same function but they are quite different in every aspect. The Alternator is used to produce three phase power from mechanical power.

What are the main characteristics of a synchronous motor?

Characteristics of Synchronous Motor are constant speed motors. The speed of the motor is decided by the number of poles and frequency. Compared to an induction motor, it is very sensitive to sudden changes of load. This causes a hunting of the rotor and finally leads to stability problems.

How does the behavior of a synchronous motor differ from that of a 3 phase induction motor?

A three-phase synchronous motor is a doubly excited machine, whereas an induction motor is a single excited machine. The induction motor has self-starting torque whereas the synchronous motor is not self starting. It has to be run up to synchronous speed by any means before it can be synchronized to AC supply.

What is the difference between the synchronous and asynchronous induction motors?

The synchronous motor is a type of AC motor that runs at synchronous speed. The asynchronous motor is a type of AC motor that runs on speed less than the synchronous speed. It operates on the principle of magnetic interlocking between rotor and stator field.
