ータ。[Claims for Utility Model Registration] (1) A rotor made of permanent magnets, a drive circuit that detects the rotor position and alternately switches semiconductor switching elements, and a winding that generates magnetic flux using the current supplied from the drive circuit. A stator core consisting of two blocks that guide the magnetic flux generated from the wire portion and the winding portion to the rotor, are arranged around the rotor, and have an air gap at the ends where they touch each other, and the stator core. A brushless motor characterized in that it is equipped with a bearing having a bearing stand formed by resin insert molding in a stator core and extending between the blocks. (2) The brushless motor according to claim 1, wherein the winding portion includes two closely wound windings each generating magnetic flux in opposite directions.
