Patent ID: 6848164

Claim:
A magnet fixing method of a linear servo motor, the motor comprising a stator composed of a plurality of magnets coupled to an upper surface of a stator body via a pure iron plate and a mover composed of a coil until coupled to a lower surface of a mover body, where the mover is horizontally moved on the stator by thrusts induced between the coil until and the plurality of magnets, the method comprising the steps of: injection-molding a cage formed with a plurality of insert holes grooves continuously arranged at a predetermined interval wherein the insert grooves are formed as deep as the magnets can be inserted; coupling a plurality of magnets into the plurality of insert grooves formed on the cage in an alternative method; and attaching the cage and the plurality of the magnets assembled by the coupling step to an upper surface of the pure iron plate simultaneously, by way of adhesives, wherein the cage encases and protects the magnets from being exposed outside.
