Abstract:
An angle detector detects an operation angle of an electric actuator having an electric motor. The electric motor generates rotation force when being energized. The angle detector includes a controller. The controller calculates an average current flowing through the electric motor during operation of the electric actuator. The controller calculates the operation angle of the electric actuator from a predetermined formula by using the average current.
