PURPOSE:To switch a 180 deg. energizing control and a 90 deg. energizing control by relatively movable disposing energizing control Hall elements to an exciting coil to first and second stators. CONSTITUTION:A motor 1 has a stator 4 including a structure in which two stator sets 2, 3 having magnetic hollow rings are superposed in upper and lower stages. Hall elements for controlling energization to exciting coils are relatively movably disposed at the sets 2, 3. A cylindrical magnet rotor is so secured as to rotate integrally with a rotary shaft 14. |
