PHASER DIAGRAM OF SYNCHRONOUS RELUCTANCE MOTOR

 

The synchronous reluctance machine is considered as a balanced three phase circuit, it is sufficient to draw the phasor diagram for only one phase. The basic voltage equation neglecting the effect of resistance is

 



V = E – j IsdXsd – j Isq…………(1.1)

 

Where

 

V is the Supply Voltage

 

Is is the stator current

 

E is the excitation emf

 

Ȣ is the load angle

 

ɸ is the phase angle

 

Xsd and Xsq are the synchronous reactance of direct and quadrature axis

 

Isd and Isq are the direct and quadrature axis current

 

I = Isd + Isq…………….(1.2)

 

Isd is in phase quadrtur with E and Isq is in phase with E.

 

 

V = E – j IsdXsd – j IsqXsq

 



Equation (9) is the torque equation of synchronous reluctance motor.


Plotting the equation (9) as shown in fig indicates that the stability limit is reached at Ȣ /4

 

And by increasing g load angle torque also increases.


In synchronous reluctance motor, the excitation emf(E) is zero.
