<P>PROBLEM TO BE SOLVED: To provide a bus bar unit that can be reduced in size in the axial and diametric directions and, moreover, secure satisfactory working ease of assembling, and a brushless motor using this bus bar unit. <P>SOLUTION: A ring-shaped bus bar unit 50 for supplying electricity to a coil comprises a plurality of phase-use bus bars 30U to 30W each having a phase terminal to be connected to one end of the coil and a neutral point-use bus bar 30N having a neutral point terminal to be connected to the other end of the coil, and a bus bar holder 51 that holds the bus bars 30U, 30V, 30W, and 30N. In the bus bar holder 51, the bus bars 30U, 30V, 30W, and 30N are stacked one over another in the diametric direction; each phase terminal is formed extending outward in the diametric direction from one side in the axial direction, and the neutral point terminal is formed extending outward in the diametric direction from the other side in the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
