<P>PROBLEM TO BE SOLVED: To make small an eddy current generated where a rotor core and a stator core do not face each other, and flowing in principal surfaces of a rotor plate and a stator plate, and to prevent reluctance torque from decreasing in a place where the rotor core and stator core face each other across a gap. <P>SOLUTION: A motor 10 includes a rotor core 16 which is formed by stacking rotor plates 16a along a rotary shaft 17, and a stator core 18 which is formed by stacking stator plates 18a along the rotary shaft 17 and coaxial with the rotor core 16, and faces the rotor core 16 across a gap 21. The rotor plate 16a of the rotor core 16 nearby an end in the direction of the rotary shaft 17 has a plurality of slits nearby the gap 21, and the stator plate 18a of the stator core 18 nearby an end in the direction of the rotary shaft 17 has a plurality of slits nearby the gap 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
