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…
Effect of Load on Synchronous Motor
The synchronous motor runs at a synchronous speed, which depends on the supply frequency. The operation of a synchronous motor is unique when compared to that of a DC motor…
Synchronous Motor: Construction, Working Principle & Applications
A synchronous motor is an AC motor, which is identical to the alternator or synchronous generator. Similar to the dc generator, the synchronous generator can be made to run as…
