what is the difference between motor and generator?

The Motor converts electric energy into mechanical energy, whereas generator does the opposite. ... The Shaft of the motor is driven by the magnetic force developed between armature and field windings whereas, in the case of the Generator the Shaft is attached to the rotor and is driven by mechanical force.

A generator or a dynamo is a device which converts mechanical energy to electrical energy. The generator was originally designed by Nikola Tesla. Principle : Generator works on the principle of electromagnetic induction. Whenever the magnetic field linked with a coil changes , an induced emf is setup in coil.

The real difference, is the fact that "motors" run on electricity, while "engines" run on combustion. ... On the rare occasions we encounter one, we refer to a steam locomotive as an engine, the same word that we give to the motive power of an aircraft. But all electrical devices are driven by motors.

An A.C. generator converts mechanical form of energy into electrical form. A D.C. motor is a device which converts electrical energy into Mechanical energy. Both these devices consist of a coil that rotates inside the magnetic field of a magnet.

AC and DC generators both use electromagnetic induction to generate electricity. However, the process they use is different. An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction.

Performance has a huge impact. Synchronous motor, like induction motor (ie asynchronous motors), is a common AC motor. Synchronous motor is the heart of the power system. ... Synchronous generator, that is, an alternator with the same rotor speed as the rotating magnetic field of the stator.

As nouns the difference between alternator and motor is that alternator is an electric generator which produces alternating current through mechanical means while motor is a machine or device that converts any form of energy into mechanical energy, or imparts motion.

The main difference between them is in regard to what spins and what is fixed. 1. In an alternator, electricity is produced when a magnetic field spins inside the stator (windings of wire). In a generator, on the other hand, the armature or windings of wire spin inside a fixed magnetic field to generate electricity.

Alternator vs. Generator: The Differences. ... The alternator converts mechanical energy into AC while a generator converts it into both AC and DC. Alternators have a rotating magnetic field, and a generator has a stationary magnetic field.

Generators use electromagnetic induction to convert mechanical energy into electrical energy. In an AC, or alternating current, generator, the electrical current periodically reverses direction. With a DC, or direct current, generator, the current flows only in one direction.

The alternator induces the AC, whereas the generator causes both the AC and DC power. The generator produces the alternating current which is converted into DC by the help of the commutator. ... The armature of an alternator is stationary, and in the case of the generator, it is rotating.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

Motor has a dc current as an input and provides mechanical output. Generator has a mechanical energy as an input and provides DC current as an output. Motor uses cummulators for changing the magnetic field polarity whereas in generator they are used to cancel the polarization effect. Motor uses Fleming left hand rule.

The DC motor is a ready made generator that will generate electricity. All that you have to do is turn the Axle of the generator using a mechanical outside source of energy .

The difference between inverter and generator in how each operates explains the significant dissimilarity between conventional generators and inverter generators. A generator produces electrical power, while an inverter draws power from a fixed DC source and uses a microprocessor to invert DC to AC.

An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves. ... The two backup generators are used for different purposes.

What's the difference between a motor and an engine? ... The Oxford English Dictionary defines “motor” as a machine that supplies motive power for a vehicle or other device with moving parts. Similarly, it tells us that an engine is a machine with moving parts that converts power into motion.
