Basic construction and working of a DC Generator.

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances.

The initial electromagnetic generator Faraday disk was invented by British scientist namely Michael Faraday in the year A DC generator is an electrical device used for generating electrical energy. The main function of this device is to change mechanical energy into electrical energy. There are several types of mechanical energy sources available such as hand cranks, internal combustion engines, water turbines, gas and steam turbines. The generator provides power to all the electrical power grids.

DC Machine

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'.

Typically, these motors are deployed in equipment that requires some form of rotary or motion-producing control. Direct current motors are essential components in many electrical engineering projects. DC motors fall into different categories, depending on their construction. The most common types include brushed or brushless, permanent magnet, series, and parallel. These brushes are usually kept in close proximity to the commutator. Other useful functions of brushes in dc motors include ensuring sparkless operation, controlling the direction of current during rotation, and keeping the commutator clean.

Difference between DC Motor and DC Generator

DC Machines v. The DC generator can operate at any speed within mechanical limits but always outputs a Construction Mining Production Line Products This article outlines basic construction and working of a DC Share; Like

A DC Machine is an electro-mechanical energy conversion device. The AC motor is invariably applied in the industry for conversion of electrical power into mechanical power, but at the places where the wide range of speeds and good speed regulation is required, like in electric traction system, a DC motor is used. The construction of the dc motor and generator is nearly the same.
