Inductors in Series
Inductors in series have a total inductance value that includes the effect of both the self-inductance and mutual inductance. An inductor is nothing but a coil of wire wound around…
Mutual Inductance and coupling coefficient
Mutual inductance is the basic operating principle of electrical machines such as transformers, motors, and generators. It is applied to any electrical component that needs interaction with another magnetic field. This…
Inductance of a coil
Inductance is the property of an inductor that opposes any change of current through the coil. An inductor has an important property: when the flux linking the coil changes, an…
What is an Inductor?
An inductor is a two-terminal passive electronic component that is capable of storing electrical energy in the form of a magnetic field when current flows through it. It is also…
Types of torque in synchronous motor
The torque required to operate the synchronous motor at every moment from its initial state to final shutdown is important in understanding its characteristics. Also to use the synchronous motor…
V curves and inverted v curves of synchronous motor
The graphs obtained by plotting the armature current and field current of a synchronous motor are called the V curves. Similarly, the inverted V curves give the relation between the…
Effect of varying excitation of synchronous motor with constant load
In a synchronous motor, the change in field excitation affects neither the speed nor its output. But it affects the power factor and armature current for constant supply voltage and…
Starting methods of synchronous motor
A synchronous motor is an AC electric motor that always rotates at a synchronous speed. This speed is achieved with the help of the rotating magnetic field produced by the…
Equivalent circuit and Phasor diagram of synchronous motor
The phasor diagram of synchronous motor is used for understanding the behavior of the motor under different load conditions. We will discuss the easiest way of drawing the phasor diagrams…
