PROBLEM TO BE SOLVED: To provide an insulator shape which secures an alignment property of a coil end laminated in a first layer and in multiple layers in a usual winding method of an inner type nozzle winding system with a common slot shape. SOLUTION: In one edge 331 of a corner on the side where a coil starts to be wound, which is either of both slot side corners of tooth end faces 33, coil holding grooves 34 are formed to all coils from a winding start to a winding end in the first layer according to a coil wire diameter to be wound. An upper-side insulator 301 and a lower-side insulator 302 are oppositely held to both end faces of core teeth 12. A slot insulating paper 50 is held as an in-slot insulator to compensate between both insulators. COPYRIGHT: (C)2011,JPO&INPIT
