Patent ID: 8120216

Claim:
An electric motor comprising: a stator core; a plurality of coils of a plurality of phases, which are wound around the stator core and rotate a rotor by an electromagnetic force; an insulator that insulates the coils and the stator core; a plurality of busbars that are fixedly buried in the insulator, and relay a feed of power to the coils; and a plurality of driving circuit connecting terminals, integrally formed with the busbars, respectively, the driving circuit connecting terminals including surfaces that are exposed from the insulator and being directly connected to an external driving circuit for controlling a driving current leading to each phase of the coils, without connecting through a separate connecting member, such that the surfaces of the driving circuit connecting terminals that are exposed from the insulator abut against a surface of the external driving circuit which faces the plurality of coils, wherein the driving circuit connecting terminals comprise a flat plate shape so as to extend in parallel with the surface of an external driving circuit board which faces the plurality of coils, and wherein a plurality of nuts buried in the insulator and a plurality of bolts inserted through the driving circuit board are screwed together respectively, such that the driving circuit board is disposed at an end of the insulator and the busbars and the driving circuit on the driving circuit board are connected electrically.
