Abstract: A signal processing device includes two to N pieces of AD converters provided independently of one another and each having at least one channel to which the sensor signal is input. The signal processing device is configured to calculate a current sum value as a sum of the N pieces of the converted signals corresponding to currents flowing in and out of the connection point with respect to the converted signals output from the AD converters and, when an absolute value of the current sum value is greater than a determination threshold, determine that any of channels of any of the AD converters is abnormal.

Abstract: A control apparatus sets a value of the field current command and a value of the armature related command in accordance with drive information and the setting information stored in the storage unit; the value of the field current command and the value of the armature related command correspond to the obtained drive information. The control apparatus controls a field current flowing through the field winding to the set value of the field current command, and controls a current flowing through the armature winding or a voltage applied to the armature winding to the set value of the armature related command.
