PURPOSE:To obtain a motor which unnecessitates a commutator and a brush with less power consumption by disposing a rotor arranged on the outer peripheral surface with prescribed number of permanent magnets oppositely to electromagnets, arranging reed switches above and below the electromagnet and controlling the energization of the switch. CONSTITUTION:A prescribed number of permanent magnets 1a-1d are disposed on the outer peripheral surfaces so that the same poles direct toward the outside to form a rotor 1, and are disposed oppositely to the electromagnet 3. In this case, the permanent magnets 1a-1d are disposed oppositely to the end 3d of the electromagnet 3, and the rotational shaft 2 of the rotor 1 is extended along the central line of the electromagnet 3. Further, reed switches 7, 8 are disposed above and below the electromagnet 3, to detect the rotary positions of the permanent magnets 1a-1d to allow the electromagnet 3 to sequentially generate attracting or repelling force, thereby rotating the rotor 1. |
