The presence of the term cosα in the torque equation very well signifies that unlike force the torque at all position is not the same. It, in fact, varies with the variation of the angle α (alpha). To explain the variation of torque and the principle behind the rotation of the motor...
Working principle of DC motors 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. Th...
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...
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...
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 Commutator The commutation’s main goal is to keep thetorqueoperating on the armature in the same direction at all times. The armature generates alternating voltage converted to direct current via the commutator. More precisely, the commutator controls the direction of the electro...
DC machine works on the electromagnetic induction principle. There are different tests performed on DC machines to know their performance and efficiency. So, one of the most important tests among them is the retardation test. The DC machine’s efficiency mainly depends upon its losses because when...

Theworking principle of a BLDC(Brushless DC) motor is based on electromagnetic forces similar to that of a Brushed DC motor. It revolves around the Lorentz force law, which states that when a current-carrying conductor is placed in a magnetic field, it experiences a force. In this case, th...
The working principle of a MOSFET depends upon the MOS capacitor. The MOS capacitor is the main part of MOS-FET. The semiconductor surface at the below oxide layer is located between the source and drain terminals. It can be inverted from p-type to n-type by applying positive or negative...
