Difference between Dc Motor and Dc Generator

Dc Motor and Dc generator are two types of motors that work on the Faraday’s laws of induction. Both are very common and are found throughout many industries. Though they are considered the same in many ways but their operations differ from each other. Dc motor operates differently than a Dc generator. Both have different winding components which creates energy using different magnetic fields. The flux change of the output is also slightly different in a Dc generator and Dc motor. The induced current in both motors move and the repetitive actions produce energy. Dc generator and Dc motor create magnetic fields through their winding coils.

    Dc Motor

    Due to their winding coils, a Dc motor’s components rotate and create magnetic fields. The rotor is one part in a Dc motor that is also called a stationary component while other pieces move with the repulsion of the magnetic field that creates energy. Slip rings are the other main components of a Dc motor as current is delivered through the rotor. Here permanent magnets make sure that the whole process of sending the current through Dc motor is working properly. Anybody that has seen the insides of a Dc Motor will understand the key role that permanent magnets have on the overall functi0ning. At the same time, two different types of Dc motors are currently being used in various industries. One is Brushed Dc electric motor while the second is Brushless Dc electric motor. Brushed literally uses small brushes to internally maintain the electric current as brushless does not use this method. It depends on your individual needs when it comes to choosing between brushed or brushless Dc motors.

    Dc Generator

    Dc Generators consist of two winding parts which include an armature and field component. Armature actually produces energy using electromagnetic induction. The other component produces energy through a static magnetic field. In Dc generators, an armature moves towards the relevant field and makes changes in flux. With the movement of the armature, this drives different voltage that produces electro-motive force to create energy. It may sound rather technical but the principle is basic. Both components of Dc generator induce a magnetic field with repetitive relative motion. The main configuration in an armature and field components allows the motor to use different terminals and an external circuit. The main current comes through the completion of an external circuit that does not change polarity.
