ABSTRACT:
The present invention provides a multi-winding motor. Two three-phase exciting windings Sa, Sb are wound on each of the magnetic pole sections of divided cores9. Two kinds of discrete winding wirings A, B are wound together with the same winding number onto each of the magnetic pole sections13A-13L of the divided cores9. Divided cores9wound with the discrete winding wirings A, B are annularly disposed, and are connected in parallel with each other so that the discrete winding wirings are arranged in the order of A, B, A, B . . . within the same connection, and the exciting windings are star-connected to construct two three-phase exciting windings Sa, Sb.
