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.

## 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'.

Premium Membership. Learn from experienced power engineers. The electrical machines deals with the energy transfer either from mechanical to electrical form or from electrical to mechanical form, this process is called electromechanical energy conversion. An electrical machine which converts mechanical energy into electrical energy is called an electric generator while an electrical machine which converts electrical energy into the mechanical energy is called an electric motor. A DC generator is built utilizing the basic principle that emf is induced in a conductor when it cuts magnetic lines of force. A DC motor works on the basic principle that a current carrying conductor placed in a magnetic field experiences a force.

## Difference between DC Motor and DC Generator

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. The reverse function of the generator can be done by an electric motor. The main function of the motor is to convert electrical energy to mechanical.

## Basic construction and working of a DC Generator.

Now there are two possibilities:. This is produced by a permanent magnet or electromagnet. The electromagnet consists of silicon steel core and copper windings. It consists of armature made of silicon steel having slots and teeth. Copper windings are placed in the slots of rotating armature.

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.

### Principle of 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. They usually contain one or more permanent magnets that spin around a fixed armature.
