Abstract:
1. A bus bar of an EPS motor, the bus bar comprising: an insulator made of insulation material and configured to form a body of the bus bar for supplying an electric power with at least three or more different polarities to a coil wound on a stator of the motor, the insulator being coupled to an upper side of the stator; a first terminal having a plurality of first coil terminal connectors protrusively formed to a circumferential direction at a first height of a periphery of the insulator; a second terminal having a plurality of second coil terminal connectors protrusively formed at the periphery of the insulator to a circumferential direction at a second height higher than the first height; and a fixing unit interposed between the first and second terminals in the insulator to fix an arrangement position of the first and second terminals arranged inside the insulator; wherein the first terminal includes a ring-shaped first body arranged inside the insulator and formed by bending a plate material of a predetermined thickness and connecting both distal ends of the plate material, and wherein the plurality of first coil terminal connectors is bent at both distal ends by being extended from the first body; wherein the second terminal includes ring-shaped second to fourth bodies in the form of a partial round bent section, wherein both distal ends of each of the ring-shaped second to fourth bodies are mutually distanced inside the insulator such that each of the ring-shaped second to fourth bodies is opened, and wherein the plurality of second coil terminal connectors is bent at a distal end by being extended from the second to fourth bodies; and wherein the first and second coil terminal connectors are alternately formed so as not to face each other.
