    摘要： The present disclosure refers to a stator (10) and an electrical machine (100). The stator (10) stator core (12) defines a central axis (C) and includes a front side (14) and a back side (16) axially displaced from each other. A plurality of stator slots (19) is provided in the stator core (12) which surround a circumference (18) of the stator core (12) and extend from the front side (14) to the back side (16), wherein the plurality of stator slots (19) includes six different stator slot groups (S1, ..., S6) among the plurality of stator slots (19). The stator (10) further includes a plurality of wave winding coils (20) including: a first lane group (LG1) and a second lane group (LG2), wherein each lane group (LG1, LG2) includes three independent lanes (L1, L2, L3; L4, L5, L6), wherein the lanes (L1, L2, L3) of the first lane group (LG1) comprise wave winding coils of a first phase (1a, 1b, 1c), a third phase (3a, 3b, 3c) and a fifth phase (5a, 5b, 5c) and the lanes (L4, L5, L6) of the second lane group (LG2) each comprise wave winding coils of a second phase (2a, 2b, 2c), a fourth phase (4a, 4b, 4c) and a sixth phase (6a, 6b, 6c). The wave winding coils of each phase (1a, 1b, 1c) of each lane (L1, L2, L3; L4, L5, L6) include a corresponding connector (22). Further, each of the wave winding coils of the same phase (1a, 1b, 1c) of different lanes (L1, L2, L3) of one lane group (LG1; LG2) supported by the same slot group (S1) among the six stator slot groups (S1, ..., S6).

    摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, and an inverter device. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the pair of output members, an output gear drivingly connected to at least one of the pair of output members. The inverter device is disposed so as to overlap a first output member that is one of the pair of output members as viewed in a direction along an up-down direction. A first coolant channel through which a coolant for cooling the rotating electrical machine passes and a second coolant channel through which a coolant for cooling the inverter device passes are provided in the case so as to communicate with each other.
