PROBLEM TO BE SOLVED: To prevent electric equipment, having a movement quantity detecting device detecting the position of a moving body, from decreasing in positioning resolution owing to a cumulative error due to rotor malfunction and variance in machining precision and fitting precision variance among components. SOLUTION: Deviation of the reference position 24 of a part to be controlled from the reference position 8 of a position sensor 1 giving the position information on the moving body is detected. According to the deviation quantity, positioning of the controlled part is controller. Further, when the setting position is changed, the moving body is moved to the target position after being moved to the reference position 8 of the position sensor 1. |
