PROBLEM TO BE SOLVED: To make a coil compact by improving the winding method of the coil and to prevent disorder in aligned state of a coil wire in a coil manufacturing process. SOLUTION: In this concentrate winding coil, a coil wire is wound so as to form a plurality of layers, and the coil wire is wound so as to form a row in every layer. At this time, a layer shift part U1 in which the coil wire is shifted from one layer to a next layer and a row shift part C2 in which the coil wire is shifted to a neighboring row inside the next layer are deviated to separate positions in the circumferential direction of the coil. Due to a layer shift and a row shift, the inclination and the floating of the coil wire are divided, and it is possible to prevent a lump from being generated in the end- face of the coil. In addition, it is suitable that the coil wire whose layer is shifted is supported by a plate or the like so as to suppress the inclination of the wire. In another way, row shift parts are arranged in different positions in every layer. In addition, in another way, a layer shift part and a row shirt part are arranged in the corner part of the coil. |
