相通電されるディスク型ブラシレスファンモータ。An 8-pole magnet rotor having N and S magnetic poles alternately, and a conductor portion that is provided face-to-face with the magnet rotor and contributes to generated torque, the opening angle of which is substantially equal to the magnetic pole width of the magnet. In a disc-type brushless fan motor that includes a stator armature consisting of one wound frame-shaped armature coil and one position detection element, each of the armature coils contributes to the generated torque. The conductor portion is formed to extend so as to face different poles that are 180 degrees symmetrical, and the conductor portion in the outer circumferential direction that does not contribute to the generated torque is bent in the vertical direction, and the above-mentioned A coking generating means is provided which generates coking at a position approximately 1/4 magnetic pole width of the magnetic rotor in front of the conductor portion contributing to the generated torque of the armature coil to eliminate dead points. Features: 1 position sensing element, 1 armature coil. 1 of 1
A disc-type brushless fan motor that is energized in phase.
