摘要： A stator for a rotating electrical machine is disclosed that includes a stator core and a stator coil of a plurality of phases. The stator coil of the plurality of phases is formed by winding a plurality of double-wound coils of each phase around the stator core along an entire circumference of the stator core. Each of the plurality of double-wound coils concentrically include a coil portion with a larger circumference length and a coil portion with a shorter circumference length. The double-wound coil of each phase includes a first double-wound coil farthest from a neutral point and a second double-wound coil other than the first double-wound coil. Of the first double-wound coils of first to third phases, only the combination of the first double-wound coils of the first and second phase overlaps in a specific circumferential section corresponding to at least one slot, and the first double-wound coils of different phases are inserted in different slots.

摘要： A vehicle drive device (100) includes a rotary electric machine (MG) disposed on a first axis (A1), an output member (OUT) disposed on a second axis (A2) parallel to the first axis (A1), an inverter device (INV), a terminal block (50) for electrically connecting a rotary electric machine-side bus bar (8) and an inverter-side bus bar (7), and a case (1). The case (1) includes a first housing chamber (20) for housing the rotary electric machine MG, a second housing chamber (30) for housing the inverter device (INV), and a partition wall (11) for separating the first housing chamber (20) and the second housing chamber (30). A terminal block (50) is disposed such that an arrangement area of the terminal block (50) in an axial direction (L) overlaps the rotary electric machine (MG), and disposed so as to penetrate the partition wall (11) in a radial direction (R) of the output member (OUT).
