Claims

[Scope of Claim for Utility Model Registration] 1. An insulating substrate such as a printed circuit board having air exhaust holes on the armature surface facing the field magnet, and having air suction holes on the outer periphery of the insulating substrate. A disc-type brushless motor with a structure suitable for forced cooling. 2. A disk-type brushless motor having a structure suitable for forced cooling as claimed in claim 1 of the registered utility model, wherein the armature consists of a group of frame-shaped armature coils. 3 The above-mentioned armature coil is a coil formed by winding the conductor portion that contributes to the generated torque so that the opening angle is 2n-1 times the magnetic pole width of the field magnet (n is a positive integer of 1 or more). A disc-type brushless motor having a structure suitable for forced cooling as set forth in claim 2 of the utility model registration. 4. A disk-type brushless motor having a structure suitable for forced cooling according to claim 3, wherein the armature coils are arranged at regular intervals so as not to overlap each other. 5. Claim 2 of the utility model registration claim, characterized in that the armature has a position detection element, and the position detection element is disposed on the surface of the insulating substrate facing the cavity within the frame of the armature coil. A disk-type brushless motor having a structure suitable for forced cooling according to any one of items 4 to 5. 6. Utility model registration claim 5, characterized in that the position detection element is provided at a position on the insulating substrate that is in an equal relationship with the conductor portion that contributes to the generated torque of the armature coil.
