1. A bus bar comprising:
- an insulator;
a first power terminal disposed in the insulator;
a second power terminal disposed in the insulator;
a third power terminal disposed in the insulator; and
a neutral terminal disposed in the insulator,wherein central axes of a plurality of virtual circles extended from the first power terminal to the third power terminal having curvature are different,wherein an inside surface of a second end of the first power terminal faces an outside surface of the second power terminal, and an outside surface of a first end of the first power terminal faces an inside surface of the third power terminal.

Abstract
A bus bar includes an insulator and a plurality of terminals inserted into the insulator and connected to the coil of a stator. The central axes of virtual circles extended from the inner circumferential surfaces of the plurality of terminals are differently disposed. The insulator may have a simple structure because the terminals having the same shape are assembled. The productivity of an assembly process can be improved.

13. A motor, comprising:
-
a stator configured to comprise a stator core and a coil wound on the stator core; and a bus bar combined with the stator, wherein the bus bar comprises an insulator and a plurality of terminals disposed in the insulator and connected to the coil, and wherein central axes of virtual circles extended from the plurality of terminals are different, wherein the plurality of terminals comprises a plurality of power terminals connected to a three-phase power source and a neutral terminal, wherein a central axis of virtual circle connecting central axes of the plurality of power terminals is identical with a central axis of the neutral terminal, wherein an angle between the central axes of the plurality of power terminals is identical around the central axis of the neutral terminal. - View Dependent Claims (14, 15)
