摘要： A brushless motor according to the present invention is provided with a tubular stator case, a stator core fitted into the stator case, and a rotor rotatably supported via a bearing inside the stator core. The stator core includes a tubular yoke portion and a plurality of split cores which are detachably mounted on the tubular yoke portion. A plurality of commutating-pole teeth which extend radially inward are integrally formed on an inner peripheral surface of the tubular yoke portion at regular intervals in the peripheral direction of the tubular yoke portion; and a root portion of each of the commutating-pole teeth has inclined shoulders which are gradually enlarged radially outward.

摘要： A brushless motor according to the present invention is provided with: a tubular stator case; a stator core; and a rotor. The stator core includes a tubular yoke portion and a plurality of split cores. A plurality of dovetail grooves are formed in an inner peripheral surface of the yoke portion; each split core has a coil bobbin which has a mounting hole so as to penetrate in a radial direction, and a split teeth which is mounted into the mounting hole of the coil bobbin. The coil bobbin has a winding portion, and flange portions, and a clearance portion into which a winding starting end of the coil is strayed from the winding portion is formed on the inside of the one of the flange portions by reducing the thickness of the flange portion such that.
