As described above, according to the present invention, it is completely unnecessary to install an insulating film every time a drive coil is loaded as in the past, and therefore work efficiency can be significantly improved. Not only is it possible to eliminate insulation defects in the coil section, making it easy to install the coil, but also because the coil locking protrusion is made of a magnetic material, the magnetic resistance of the coil section can be reduced. Therefore, since the interlinkage magnetic flux naturally increases, the output of the entire motor can be increased.As mentioned above, since a part of the coil support plate is made to protrude to form the coil locking protrusion, the structure is improved. It is possible to provide an unprecedented and excellent coil attachment mechanism for a brushless morph, which is simple and can significantly improve its durability and productivity, and a method for forming the same.
