1. A bus-barwire comprising:
a frame, being an insulator;
a plurality of busbars,
wherein each of the busbars comprises a main body embedded in the frame and extending along a circumferential direction of the frame, and a plurality of connecting parts connected to the main body and protruding outside of the frame, the plurality of connecting parts being configured to connect wiring ends of motor stator windings; and
a plurality of terminals, being connected to the plurality of busbars, for connecting to a power source,
wherein, all the main bodies of the busbars are arranged in a stack along an axial direction of the frame and are spaced apart from each other, all the connecting parts of the busbars are spaced apart along the circumferential direction of the frame, and all the connecting parts of the busbars are distanced from end surfaces of the stator windings and remain flush in the axial direction of the frame,
wherein the frame comprises a ring bracket and a plurality of strip brackets integrally connected with the ring bracket, and all the main bodies of the busbars are embedded in the ring brackets, and the plurality of strip brackets correspond to the plurality of terminals one-to-one, and a part of each of the terminals is embedded in the corresponding strip bracket, and
wherein the terminal is connected to one of the connecting parts of the corresponding busbars, in a projection of a plane perpendicular to a central axis of the frame, the strip bracket is arranged asymmetrically with respect to the terminal in a thickness direction of the terminal, and a dimension of a part close to the corresponding connecting part configured to connect to the wiring end is smaller than the dimension of a part far away from the corresponding connecting part configured to connect to the wiring end.
