Title:
METHOD OF MANUFACTURING CONCENTRATED WINDING COIL
Document Type and Number:
Japanese Patent JP2012139098
Kind Code:
A
Abstract:
To prevent alignment property of a wire material at a core slot part from lowering in a concentrated winding coil to achieve a high space factor coil.
With a concentrated winding core, in order to maintain the alignment state of a slot part inserted into a stator core, column transition and layer transition need to be performed in a coil end part. By installing a wire material guide holding mechanism near a winding bobbin, guiding the position of a wire material before winding the wire material on to a bobbin, and depressing the wire material after winding, alignment disturbance of a coil wire can be prevented and a high space factor coil can be achieved.
