本体に取付けた、 ことを特徴とするブラシレスフアンモータ。[Claims for Utility Model Registration] A magnetic polarity system that has a stator forming an armature and a rotor equipped with a magnet, a fan is attached to an output shaft connected to the rotor, and detects the rotational position of the magnetic pole of the rotor. The motor includes a detection means and a motor control circuit that rotates the rotor by switching the excitation polarity of the armature coil in synchronization with the switching of the magnetic polarity of the rotor by detecting the rotational position, and the outer periphery of the motor body has an air blowing path by a fan. In a brushless fan motor, the edge of a box-shaped heat sink with an outer circumference approximately the same as the outer circumference of the motor body faces the side of the stator opposite to the output shaft, and the motor control circuit is arranged on a printed circuit board. A brushless fan, characterized in that the brushless fan is installed in a box-shaped interior of the heat sink together with the printed circuit board, is molded with resin integrally with the heat sink, and the heat sink is attached to a motor body with a heat insulating material interposed therebetween. motor.
