Vector diagram of induction motor

Transformer Phasor Diagram under Load (HINDI) . Diagram on which one or more vectors can be represented is referred as vector diagram. On such diagram , alternating quantities are represented by arrow. The length of the arrow represents the rms value of the alternating quantity.

So it is also called the rotating transformer.

If the condition changes, we need to draw the phasor diagram again.

On the context of induction motor , which is .

We will discuss here the simplest way of drawing the phasor diagram for an AC series motor. Before we draw phasor diagram , let us write the various notations for each quantity at one place. Here we will use: Rs to represent the resistance of the series field.

PHASOR DIAGRAM OF THE INDUCTION MOTOR. Two- wattmeter method to measure 3-phase active power. One component defines the magnetic flux of the motor , the other the . As the single phase system is more economical and the power requirement in most of the houses, shops, offices are small, which . Thus no load and blocked rotor tests are performed on the motors.

As the name suggest no load test is performed when rotor rotates with synchronous speed and there is no load torque. This test is similar to the open circuit test on transformer. Actually, to achieve synchronous speed in an induction motor is impossible. Note: calculations are vector quantities. Phasors are an efficient method of analyzing AC circuits when the frequencies are the same (the amplitudes do not need to be).

The rotor of the slip ring induction motor is connected to an ac source and stator is short circuited. The single phase induction motors are made self starting by providing an additional flux by some additional means. Split phase induction motor (а) Connection. Capacitor start induction motor.
