Abstract
PURPOSE: To improve starting characteristic by constituting the rectifier for rectifying the AC current produced in the armature of AC exciter provided at the rotor side while including the thyristor thereby blocking the current from the rectifier during starting.
CONSTITUTION: The armature 5 of AC exciter provided at the rotor side 7 of brushless synchronous motor is connected to rectifying circuit 8 containing diodes D1-D3, thyristors T1-T3 to supply the output to field winding 2. consequently when taken out the gate firing signal for thyristors T1-T3 by utilizing the voltage induced in the armature 5 of AC exciter, thyristors T1-T3 don't fire if DC excitation isn't provided on AC exciting field winding 6, and the field winding current flows only through the discharging resistor 3 during the starting thereby contains no DC component for producing the torque thus to improve the starting characteristic.
