Claims

[Scope of utility model registration request]

In a small electric motor, an encoder disk is attached to the axial side surface of the rotor so as to rotate integrally with the magnetic poles of the rotor in a certain relationship, and a sensor for detecting the signal of the encoder disk is attached to a fixed member such as a motor case. , wherein the sensor is held by an adjustment lever, the fulcrum of the adjustment lever is placed at or near the axis of the rotor, and the sensor is mounted so as to be rotatable in the same direction as the arc formed by the rotor. Electric motor.
