DC motor working Principal | Dc Motor Construction | How does an Electric Motor Work
DC motor Working Principle - Video gives a brief explanation in form of animation of how does DC Motor works. Also, you can view working principles on elementary models with poles, commutators, brushes, turns, and what role in working principles has mechanical force.
==================================================================
PRINCIPLE OF DC MOTOR
This DC or direct current motor works on the principal, when a current-carrying conductor is placed in a magnetic field, it experiences a torque and has a tendency to move.
This is known as motoring action. If the direction of current in the wire is reversed, the direction of rotation also reverses. When magnetic field and electric field interact they produce a mechanical force and based on that the working principle of the DC motor is established.
The direction of rotation of this motor is given by Fleming’s left-hand rule, which states that if the index finger, middle finger, and thumb of your left hand are extended mutually perpendicular to each other and if the index finger represents the direction of the magnetic field, middle finger indicates the direction of the current, then the thumb represents the direction in which force is experienced by the shaft of the DC motor.
Structurally and construction wise a direct current motor is exactly similar to a DC generator, but electrically it is just the opposite. Here we unlike a generator we supply electrical energy to the input port and derive mechanical energy from the output port.
