PURPOSE:To reduce the mechanical unbalance amount of a winding type rotary electric machine and to shorten the crossover track between coil groups by suitably setting the number of the connecting circuits of the winding with respect to the number of the poles of a rotor, and substantially equally arranging the connecting sections between the phases of the windings in a circumferential direction. CONSTITUTION:The number of the connecting circuits of U-phase coils U1-U6, V-phase coils V1-V6 and W-phase coils W1-W6 are set to np/2 (where n is natural number) with respect to the number (p) of the poles of a winding. Coil groups are commonly connected in a star type to form interphase connecting sections N1, N2, N3. The sections N1-N3 are arranged substantially at an interval of 120 deg. in a circumferential direction.
