Abstract: A brushless motor includes a stator and a rotor rotatably supported inside the stator. The rotor has a rotor yoke formed by laminating a large number of steel plates, the rotor yoke has an even number of magnetic pole portions protruding outward, and a field magnet is fitted to each of the magnetic pole portions or every other magnetic pole portions. A magnetic sensor is disposed within the range in which the sensor can directly detect a magnetic flux leaking outside from an end face of the rotor and is less affected by irregular fluxes near the rotor end face, so that this sensor can detect a peak point of a flux density around the rotor. A magnetic sensor is disposed within the range where the influences of the irregular fluxes are small. A magnet to be detected is fitted to the rotor end face, and a magnetic sensor for one direction and a magnetic sensor for the other direction are disposed near the trajectory of rotation of the detected magnet.
