Abstract
A brushless motor includes: a columnar rotor including magnets; a stator including at its center a space for placing the rotor; a housing member that houses the rotor and the stator; and a detector that detects a signal dependent on a rotational position of the rotor based on variation in a magnetic field associated with a rotation of the rotor. The housing member includes a front bell that supports a portion of the rotating shaft of the rotor and a housing body that supports another portion of the rotating shaft of the rotor. The front bell includes a mount fitted with the detector. The mount projects from the base toward an end face of the rotor.
