ABSTRACT:
Of two bearings supporting a rotor of a circuit-integrated type core-equipped brushless motor, a part of an outer periphery of the bearing, which is disposed at a position near a stator core, is allowed to directly abut on an inner periphery of a hole formed in a center of the stator core, and therefore, reduction in thickness, reduction in diameter, space-saving and enhancement in output power can be realized. The stator core is fixed to the casing by causing projected parts provided at the housing to bite into second notched parts formed inside first notched parts formed at the stator core and crimping them, whereby the problem of a decrease in a winding space accompanying reduction in a diameter of the stator core is solved, and reduction in thickness, reduction in diameter, space-saving and enhancement in output power are achieved.
