Abstract
A rotation angle detector includes a voltage detector receiving a supply of voltage from a first power source and detecting a motor rotation regarding a motor, the motor rotation more specifically detected as (i) a rotation angle of the motor and (ii) a number of rotations of the motor. Also, a second power source is disposed separately from the first power source and supplying voltage to the voltage detector. Thus, even when the voltage of the in-vehicle battery lowers or the voltage supply therefrom is interrupted, the voltage supply to a voltage detector is continuous from the power storage device, thereby enabling a continuous detection of the rotation angle and the rotation number of the motor.
