ABSTRACT:
To obtain an adjustment method of rotor position detection of a synchronous motor with excellent productivity. An adjustment method of rotor position detection of a synchronous motor, wherein a synchronous motor having a stator wound around a stator coil and a rotor provided with magnetic poles, and a rotational position detector having a sensor rotor fixed to the rotor and a sensor stator disposed opposite to the sensor rotor for detecting a rotational position of the rotor are provided, and wherein an amount of deviation between the rotational position of the synchronous motor determined from an output of the rotational position detector and an actual rotational position of the synchronous motor is adjusted, the method comprising: a step of detecting the amount of deviation during rotation of the synchronous motor; and a step of mechanically adjusting a relative position between the rotational position detector and the synchronous motor based on a detected value of the amount of deviation, is provided.
