The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a direct current electromotive force when it is led out from the brush end through the commutator and the commutation action of the brush. The direction of the induced elec...
DC motors play a crucial role in modern industry. Understanding theworking principle of a DC motor, which we explore in this article, begins with its fundamental single loop construction. The very basicconstruction of a DC motorcontains a current carrying armature, connected to the supply end thr...
A DC motor is an electrical machine thatconverts electrical energy into mechanical energy. DC motor working is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given byFleming...
In principle, a DC motor can operate as both an electric motor and a generator, which is called the reversible principle in motor theory. When the prime mover drives the armature winding to rotate between the main magnetic poles N and S, electromotive force is induced on the armature winding...
A DC machine is an electromechanical energy alteration device. Theworking principle of a DCmachineis when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such ...
Working principle of DC motor:- A magnetic field arises in the air gap when the field coil of the DC motor is energised. The created magnetic field is in the direction of the radii of the armature. The magnetic field enters the armature from the...
what is the role of a commutator in a DC motor? What is the working principle of an electric motor? People often use the term energy crisis, implying that we are running out of energy. How can this be if energy is conserved? If we are not running out of energy, what are ...
What is the working principle of a fan?Electric MotorsFans are made of an electric motor and rotor blades. The fan is usually a single-phase induction motor and the rotor blades are optimized aerodynamically. The fan uses electricity to rotate the blades which then drive air in the room ...
