PROBLEM TO BE SOLVED: To provide a core which is not deteriorated in insulation performance due to the damage of a winding, does not form a gap between divided cores caused by the rigidity of the winding, hardly causes the breakage of the winding, and is easy in the traverse of a nozzle, and to provide the divided stators and a stator. SOLUTION: The stator comprises the cores 3, 5 and 6 which form an iron core of a coil, an insulator 7 which covers the cores, and the winding 1 which is wound around the cores with the insulator interposed therebetween, and forms the coil. The core does not have a shape all of four corners of which are the same in roundness at a cross section orthogonal to the axial core of the coil. COPYRIGHT: (C)2008,JPO&INPIT
