Patent ID: 8035264

Claim:
A motor comprising: a rotor including; a rotation shaft; and a magnet thereon; a stator including; a core provided with pole teeth on an inner circumference to surround the magnet; and a coil wound around outer peripheries of the pole teeth; and a terminal block for supporting a plurality of terminal pins to be connected with ends of the coil; wherein the core has a terminal block holding part, the terminal block being located radially outside the terminal block holding part so as to be connected with the terminal block holding part via a resin connection part; wherein the terminal block holding part has a recess axially opened and filled by the resin connection part; wherein the core has the pole teeth in two layers directed axially in directions opposite from each other; wherein the terminal block holding part has the recess opened axially in one direction in correspondence with the pole teeth in one of the layers; wherein another recess is opened axially in another direction in correspondence with the pole teeth in the other layer; wherein the core is divided into two cores in a pair, each having a plate-shaped base part and the pole teeth directed axially in one of the directions from the base part that has the terminal block holding part; wherein the base parts of the paired cores facing back to back; wherein each of the terminal block holding parts are provided with a cutout; wherein the cutout formed in one of the terminal block holding parts serves as the recess opened axially in one direction, while the cutout formed in the other terminal block holding part serves as the recess opened axially in the other direction; wherein the base part of each of the two cores has a disk part provided with the pole teeth on an inner circumference thereof; wherein the terminal block holding part extends outward from the disk part with a predetermined width so as to have a terminal block facing end perpendicular to a radial line from a center of the disk part; wherein the cutout is formed in the terminal block facing end: wherein a center in a length of the cutout along the terminal block facing end is offset with respect to the radial line; and wherein each of the recesses formed in the corresponding terminal block holding part has a bottom sealed at least partially by the other terminal block holding part.
