徴とするブラシレスモータ。A cylindrical permanent magnet is brought into contact with the inner surface of a bowl-shaped rotor yoke, a stator is disposed on the inner surface of the cylindrical permanent magnet with a gap therebetween, and a plurality of stators are attached to the stator. In a brushless motor equipped with a magnetic detector that winds windings and generates an energization control signal for the stator winding, a flat annular permanent magnet is installed inside the bowl-shaped rotor yoke. The permanent magnet is arranged concentrically with the central axis of rotation of the rotor, and the permanent magnet is magnetized to have north and south poles within a range of 180° in the circumferential direction, and a position where the magnetic flux of the permanent magnet is detected. A brushless motor characterized in that a signal generating coil is disposed to face the annular permanent magnet with an air gap interposed therebetween, and to be disposed approximately in the middle of mutually adjacent magnetic poles of the stator.
