Synchronous motor circuit diagram. Synchronous motor phasor diagram. Figure 2 a shows a phasor diagram for a lagging current. Working principle of a synchronous motor.
In stator winding two effects are to be considered the effect of field cutting stator conductors at synchronous speed and the effect of stator. The stator is excited by the three phase supply and the rotor is excited by the dc supply. In case of a synchronous motor revolving field structure is to be energized by direct current dc current.
38 9 b that the phase applied voltage v is the vector sum of reversed back e m f. 11 phasor diagram of synchronous motor in order to draw the phasor diagram vt is taken as the reference phasor and below points are to be followed. The stator and the rotor are the two main parts of the synchronous motor.
Per phase equivalent circuit for a synchronous motor. Equation 2 is the preferred form since the terminal voltage is normally chosen as the reference phasor for purposes of drawing a phasor diagram. I e eb and the impedance drop ia zs in other words v eb ia zs the angle a between the phasor for v and eb is called the.
The circuit equation for a synchronous motor is thus π½π½ π¬π¬ π¨π¨ πππΏπΏ ππ π°π° ππ πΉπΉ ππ π°π° ππ π¬π¬ π¨π¨ π½π½ πππΏπΏ ππ π°π° ππ πΉπΉ ππ π°π° ππ. The stator is the stationary part of the motor and rotor is their rotating part. With a known terminal voltage we can construct phasor diagrams for the synchronous motor as shown in figure 2.
