Ac Synchronous Motor 3 Phase Wiring Diagram. How to troubleshoot 3 phase ac motors. Single phase ac supply is given to the stator winding main winding.
The 3 beside phase on the nameplate in figure 1 indicates that this is a 3 phase ac motor the motor operates on 3 phase ac power. Most industrial ac induction motors are rated 3 phase which means that the ac power supply is three separate yet interconnected single phase ac lines with the voltages across the respective windings 120 out of phase with each other. How to troubleshoot 3 phase ac motors.
Operation of this mode can be divided between four modes รข load voltage is equal to positive instantaneous ac supply voltage.
Here the only one fact is the motor continuously runs on single phase with two winding receives active power so that the net output of the motor will be reduced typically 23 rd of its rated capacity. Most industrial ac induction motors are rated 3 phase which means that the ac power supply is three separate yet interconnected single phase ac lines with the voltages across the respective windings 120 out of phase with each other. We have now placed twitpic in an archived state. C y capacitance per phase when the capacitor is connected in stars.
