What is the difference between AC and DC Generator?

In electricity generation , a generator [1] is a device that converts motive power mechanical energy into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines , gas turbines , water turbines , internal combustion engines , wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk , was invented in by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. The reverse conversion of electrical energy into mechanical energy is done by an electric motor , and motors and generators have many similarities.

AC vs DC (Alternating vs Direct Current): Similarities & Differences (w/ Chart)

Electrical Academia. The AC generator generates an output voltage which alters in amplitude as well as time whereas the DC generator generates a constant output voltage which does not change in amplitude as well as time. The electrical energy we utilize has two fundamental types, one is known as Alternating while the other one is Direct. The electric power in homes has alternating current and voltages, but in an automobile currents and voltages are constant. Both types have their own particular uses whereas the technique of producing the both is same, which is called electromagnetic induction. The machines which produce an electric power are called generators, and AC and DC generators are different from each other by the method they apply to pass the produced current to the external circuit. Characteristics AC Generator DC Generator Output Power Generates AC electric power Produces DC electric power Rings it has slip-rings it uses a split-ring commutator Current induction Output current can be induced either in the rotor or in the stator Output current is induced in the rotor ONLY Brushes Slip-rings have smooth and uninterrupted surfaces, which allow the brushes to remain in contact uninterruptedly with the slip ring surfaces.

The Electric Motor and Generator are differentiated on various factors like the main principle of working or function of the motor and generator. Consumption or production of electricity, its driven element, the existence of the current in the winding. The Difference Between the Motor and the Generator are explained below in the tabulated form. The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor. It converts mechanical energy into electrical energy.

A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf. This article outlines basic construction and working of a DC generator. Note: Theoretically, a DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. These basic constructional details are also valid for the construction of a DC motor. Hence, let's call this point as construction of a DC machine instead of just 'construction of a dc generator'. The above figure shows constructional details of a simple 4-pole DC machine.

Alternating current, or AC, is current that oscillates and changes direction at a certain frequency. You can imagine the free electrons in a wire moving back and forth, oscillating around a single fixed point. This is what happens with AC current. You might wonder if this oscillation would produce noticeable effects in the objects it is used to power because if the current is oscillating, then it is periodically zero for a brief moment before it changes direction.
