Now the sync machine is working as motor so direction of Ia is reversed. That is shown in phasor. what is the point of adding a -Ia. And shouldn't power factor be between Ia and Ef instead of -Ia and Ef. In second picture if you look at third picture, isn't direction of IaXr...
The block diagram shows the drive electronics associated with a low voltage (12 V DC) synchronous motor. These motors have aposition sensorintegrated within the motor, which provides a low-level signal with a frequency proportional to the speed of rotation of the motor. The position sensor could...
