ABSTRACT:
A method of manufacturing a field coil for motors that does not require winding of a field coil on a pole core of a stator and that improves the space factor of the field coil. On a part of a conductor, an opening is formed to pass a pole core laid out in a stator therethrough and a spiral slit is formed to pass through the conductor in the thickness direction and connect the outer circumference of the conductor and the opening. An insulation material may be provided in the spiral slit when necessary.
