PROBLEM TO BE SOLVED: To provide an inexpensive bobbin structure that may suppress deviations in an axial direction of split cores, prevent performance reduction caused by axial deviations, and improve circular ring assemblability of the split cores. ! SOLUTION: In an annular-shaped stator core and a plurality of split cores and bobbins constituting the stator core, the bobbins have wall parts at end parts in an axial direction, and have, at two or more of the wall parts, steps where the bobbins are lapped in the axial direction. The step parts suppress deviations of the split cores or the bobbins. ! COPYRIGHT: (C)2015,JPO&INPIT |
