Claims

[Claims for Utility Model Registration] 1. A rotor comprising a plurality of magnets arranged radially around a rotating shaft and a ring-shaped rotor yoke attached to the rotating shaft to support the magnets, and a rotor identical to this rotor. In a flat brushless motor consisting of a stator fixed around a transfer axis so as to be located on a radial line, an inner fixing device that fits the inner end of the magnet radially around the rotation axis and presses it onto the rotor yoke. and an outer fixture that fits the outer end of the magnet and presses it onto the rotor yoke. 2. The flat brushless motor according to claim 1, wherein room temperature curing resin is filled between the magnets. 3. The utility model registration claim 1, wherein the inner fixture and the outer fixture are comprised of a guide part into which the inner end of the magnet is fitted, and a presser part which presses the inner end of the magnet onto the rotor yoke. Flat brushless motor. 4. The flat brushless motor according to claim 3, wherein the guide portion and the holding portion of the inner fixture and the outer fixture are integrally formed. 5. The flat brushless motor according to claim 3, in which the guide portion and the holding portion of the inner fixture and the outer fixture are separated. 6. The flat brushless motor according to claim 1, wherein the outer fixture has a balance groove in which a balance weight is removably inserted.
