The DC motor is the device which converts the direct current into the mechanical work.

DC Machine : Construction, Working & Its Applications

Theoretically, the same DC machine can be used as a motor or generator. Therefore, construction of a DC motor is same as that of a DC generator. An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: " whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force". Fleming's left hand rule : If we stretch the first finger, second finger and thumb of our left hand to be perpendicular to each other, and the direction of magnetic field is represented by the first finger, direction of the current is represented by the second finger, then the thumb represents direction of the force experienced by the current carrying conductor. Above animation helps in understanding the working principle of a DC motor.

The conversion of this mechanism is known as the commutator, thus these machines are also named as commutating machines. DC machine is most frequently used for a motor. The main benefits of this machine include torque regulation as well as easy speed. The applications of the DC machine is limited to trains, mills, and mines. For example, underground subway cars, as well as trolleys, may utilize DC motors. In the past, automobiles were designed with DC dynamos for charging their batteries.

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.

Understanding DC Motor Operation Modes and Speed Regulation Techniques

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.
