106.<strong>Synchronous motor</strong><strong>Thyristor</strong><strong>Excitation</strong><strong>Circuit</strong>Part 2.gif

This excitation device is used for 625kW synchronous motors started at light load . The trigger
circuit of the device consists of three identical resistor-capacitor phase-shift triggers. Adjust the potentiometers RP3~RPs to make the RC phase shift bridge phase at
O. ~150. changes to control the magnitude of the rotor excitation current.
