子。A drive magnet is arranged so that multiple magnetic poles magnetized in the axial direction have different polarities in the circumferential direction, and a pickup magnet is used to detect the phase by opposing the pickup coil. In the rotor of a commutatorless motor provided with a rotor, the pickup magnet is connected to the axial polarity of the magnetic pole of the drive magnet so that its surface C polarity is in phase with the polarity of the surface of the drive magnet. A rotor of a non-commutated 9 motor, which is magnetized in the axial direction so as to be protruded from the drive magnet in the axial direction.
