Abstract

A control valve includes a shaft, a stopper mechanism, and a can. A stator coil is coaxially mounted around the can. Positions in a rotating direction of the rotor and the stator when the shaft is stopped by an operation of the stopper mechanism are set to be reference positions at which magnetic poles of the stator and those of the rotor are opposite to each other. The rotor is configured to be stopped at the reference position by an arrangement of the stopper mechanism. The stator coil is positioned relative to the body according to a positional relation between a fitting part formed on surfaces of the stator and the body attached to each other and an insertion part where the can is inserted into the stator, and magnetic poles of the stator and those of the rotor are made opposite to each other at the reference positions.
