V Curve Of Synchronous Motor

V Curve Of Synchronous Motor. Such curves are called Vcurves of synchronous motor These are shown in the Fig 2a As against this if the power factor (cos ?) is plotted against field current (I f) then the shape of the graph looks like an inverted V Such curves obtained by plotting pf against I f at various load conditions are called Inverted Vcurves of synchronous motor These curves are shown in the.

Synchronous motor V curves for synchronous motor give the relation between armature current and DC field current The curves are shown below A synchronous motor is capable of operating at all types of power factor ie either UPF leading or lagging power factor Lagging power factor If field excitation is such that E b < V the motor is said to be under excited and it has a lagging.

V and inverted V curves of Synchronous Motor Effect of

V curve is a plot of the stator current versus field current for different constant loads The Graph plotted between the armature current I a and field current I f at no load the curve is obtained known as V Curve Since the shape of these curves is similar to the letter “V” thus they are called the V curve of a synchronous motor.

V Curves and Inverted V Curves of Synchronous Motor

VCurve of a Synchronous motor is graphical representation of loadcurrent versus field current Set of VCurves can be drawn for the same motor each curve corresponding to particular output/input power held constant Synchronous motors are.

Experiment No. 6 ‘V’ CURVES OF A SYNCHRONOUS MACHINE

PDF fileVcurve of a synchronous shows its performance in terms of variation of machine armature current with field current when the load and input voltage to the is constant machine When a synchronmachineous is connected to an infinite bus the current input to the stator depends upon the shaftload and excitation (field current).
