Abstract:
1. An apparatus for calculating power generation torque of a power generator with a portion in which an exciting winding is provided, the power generator generating power based on rotation of the portion while an exciting current is supplied to the exciting winding, the apparatus comprising: a first detecting unit configured to detect the number of revolutions of the power generator; a second detecting unit configured to detect an output voltage of the power generator; a third detecting unit configured to detect an output current of the power generator; and a torque calculating unit configured to calculate power generation torque based on the detected number of revolutions of the power generator, the detected output voltage, and the detected output current using relationship information, the relationship information representing a relationship between the power generation torque and each of the number of revolutions of the power generator, the output voltage, and the output current.
