Zusammenfassung: | A field circuit includes a positive pole side switching element which is for controlling field current that flows in a field winding and a negative pole side switching element which is for interrupting the field current; a field circuit control section includes a field high-speed interruption determination block and a field current interruption speed control block; and at the time of interrupting the field current at a high speed, the field current is interrupted immediately by turning OFF both switching elements of the positive pole side and the negative pole side and interruption speed of the field current is controlled by intermittently driving the negative pole side switching element. |
