ブラシレスモータ。[Scope of claims for utility model registration] (1) 2P having N and S magnetic poles alternately (P is 1
A one-phase motor that is equipped with a field magnet having (a natural number of) poles as a rotor, an armature coil that is disposed on the stationary side facing the field magnet, and that can be self-started using cogging torque. In the disc-type brushless motor that is energized, when the motor casing is made of plastic, one or more protrusions are integrally formed on the inner surface of the motor casing, and an iron rod for generating cogging torque is protruded from the inner surface. The stator armature is formed by arranging the armature coil on an armature coil arrangement plate having a through hole for inserting the protrusion and the iron rod, and forming the stator armature. The stator armature is arranged on the inner surface of the motor casing by inserting the protrusion and the iron rod into the through hole, and the tip of the protrusion protruding from the upper surface of the armature coil arrangement plate is heat-welded, etc. A single-phase energized disc type brushless motor in which the stator armature is fixed to the inner surface of the motor casing by crushing it. (2) The single-phase energized disk-type brushless motor according to claim (1) of the utility model registration, wherein the armature coil arrangement plate is a printed circuit board. (3) The single-phase energized disc-type brushless motor as claimed in claim (1) of the utility model registration, wherein the armature coil arrangement plate is a stator yoke whose armature coil arrangement surface is insulated. (4) The above-mentioned armature coil arrangement plate is a magnetic substrate with an insulating layer applied to the surface of the magnetic substrate and a printed power distribution pattern formed on the surface, as stated in claim (1) of the utility model registration claim. A disc-type brushless motor that is energized in one phase. (5) Utility model registration claim No. (2), in which a stator yoke having a through hole for inserting the protrusion and the iron rod is arranged on the lower surface of the printed circuit board.
A disc-type brushless motor that is powered by one phase as described in Section 1. (6) A single-phase energized disk-type brushless motor according to claim (3) of the utility model registration, wherein a printed circuit board with electrical components disposed on the lower surface is provided on the lower surface of the stator yoke. (7) A single-phase energized disk-type brushless motor according to claim (4) of the utility model registration, wherein electric components are disposed on the lower surface of the magnetic substrate. (8) The above-mentioned iron rod is located at a position approximately 1/2 width in front of the conductor portion that contributes to the generated torque of the armature coil in the direction of rotation of the field magnet, or at a position in phase with the said position. A single-phase energized disk-type brushless motor according to any one of claims (1) to (7) of the utility model registration, in which the positions of the through hole and the armature coil are set. (9) The iron rod is located at a position approximately 1/4 magnetic pole width in front of the conductor portion that contributes to the torque generated by the armature coil in the direction of rotation of the field magnet, or at a position in phase with the said position. A single-phase energized disk-type brushless motor according to claim (8) of the utility model registration, wherein the positions of the through hole and the armature coil are set.
