Field Winding Rotating Electrical Machine

Abstract: lim­C[Problem] To provide a field winding rotating electrical machine that can release a limitation in field current within a predetermined time period in the situation of a vehicle needing the output of ordinary circumstances even in the state of field current limitations being carried out. [Solution] The present invention is provided with: a field current limiting unit (140) that when it has been determined by a field current limitation determination unit (142) that a determination value has reached a predetermined determination threshold generates a field current limiting command to a field current control unit (110) in a manner so as to limit the field current to no greater than a predetermined allowed value during a predetermined field current limitation period (T); and a field current limitation releasing unit (150) that outputs to the field current limiting unit a field current limitation releasing command in a manner so as to release the field current limitation during a predetermined field current limitation releasing period (T). The field current limiting unit releases the field current limitation during the predetermined field current limitation releasing period when having received the field current limitation releasing command from the field current limitation releasing unit.
