Abstract

PURPOSE: To permit quick attenuation of the excitation current at the time of stopping an electric revolving machine by constructing a series circuit consisting of a semiconductor element and a field discharge resistor at this time.
CONSTITUTION: At the time of stopping a synchronuous motor 1, field switches 5' are opened to cut off input current to a rectifying circuit 3 and at the same time connect a field discharge resistor 10 in series with a fylwheel diode 4. Thus, the field current in a field winding 2 is caused to flow through the flywheel diode 4 and field discharge resistor 10 and is quickly attenuated.
