PROBLEM TO BE SOLVED: To equalize the magnetic balance of a coil wound on an armature in a rotating electric machine which is equipped with an armature where (an+1)pieces of teeth (a is a natural number) for n poles are made. SOLUTION: In the 4-pole and 21-tooth of rotating electric machine, a coil 10 wound on an armature is two-layer winding, and each layer of coil 10 is wound in anΩ-form winding method in condition that the number of teeth strides is five each (the condition that a gap of four slots lies between), and besides a coil 10 (for example, a coil No. I-1 )in the first layer winding and a coil 10 (for example, a coil No.II-1) conducted severally to an optional armature piece 7b are constituted in such positional relation that they are opposed to each other in the radial direction.
