The invention relates to a rotating electric machine and a drive system thereof, aims to avoid the increasing of slot number and realizes large capacity, miniaturization and low inertia. In a rotating electric machine, each phase of a plurality of three-phase windings is divided into a plurality of partial windings, disposed on a stator core. For example, the partial windings of the U-phase are distributively arranged on four U-phase winding areas 2U1 to 2U4, and on each of these winding areas, two partial windings overlap through a pair of slots between which two teeth are interposed. At each coincident location of a pair of slots, two partial windings of different three-phase windings overlap. For example, a pair of slots on the U-phase winding area 2U1, a partial winding UA1 of a U-phase winding UA and a partial winding UB3 of a U-phase winding UB overlap. At a pair of slots on the U-phase winding area 2U1, a partial winding UG2 of a U-phase winding UG and a partial winding UB2 of a ...
