How to Change the Direction of Rotation of DC Series Motor?
In this post, we will discuss how to change the direction of rotation of the DC Series Motor. The rotational force of the DC motor
What is no load Current of Induction Motor?
The current drawn by the induction motor when it is not coupled to the driven equipment is called the no-load current of the motor. The
Current Transformer – Construction, Phasor and Errors
This article describes the current transformer – construction, Phasor, and Errors. Current transformers are widely used for measuring high currents. The Current transformer steps down
Why is Armature of Alternator Connected in Star not in Delta?
The alternator armature winding must be protected from earth faults. The earth fault protection scheme for an alternator whose armature winding is connected in a
EMF Equation of Alternator and AC Generator
An alternator or AC generator produces an AC supply. In other words, the generator or alternator converts mechanical energy into electrical energy. The rotor rotates
Thermistor: Definition,working principle and applications
What is a Thermistor? A thermistor is a type of thermal resistor whose electrical resistance increases or decreases with a change in temperature. Thus, the
Direction of Rotation of DC Motor
The Direction of rotation of the DC Motor can be reversed by reversing the direction of torque of the motor. When the motor exerts torque
Why Three Phase Induction Motor Self-Starting?
When a three-phase supply is fed to the stator of an induction motor, the stator draws current from the 3-phase supply, which produces the magnetic
What is Skin Effect? Factors affecting the skin effect
When the DC current flows through the conductor, the charge distribution throughout the conductor cross-section is uniform, and the current gets evenly distributed. Direct current
Ferrite Core Transformers- Types & Applications
What are Ferrite Core Transformers? Ferrite core transformers are made from ferrite materials. The ferrite core transformer is used for higher-frequency applications. The power transformer is
