PROBLEM TO BE SOLVED: To provide a motor structure which is so arranged as to reduce the slot ripple at low-speed revolution, by providing two pieces of motors within one casing, and sliding the attachment positions of many first and second magnet pieces constituting the first and second annular magnet bodies provided at the rotor of each motor from each other. SOLUTION: A motor structure is of such constitution that it gets smooth rotation low in slot ripple at low-speed revolution, with its magnet pieces negating slot ripple each other, by constituting a pair of motors 20 and 21 of one piece of rotor 8, and shifting each magnet piece of each annular magnet body 10 and 11 provided at the rotor 8 from each other in the circumferential direction of the rotor 8. |
