2. Description of the Related Art Conventionally, a linear motor suitable for applications requiring ultra-precision positioning and high thrust, such as a transportation system for FA equipment, is shown in FIG. FIG. 1 is an overall perspective view of a general linear motor, showing an overall configuration common to the present invention described later. Further, FIG. 4 shows a mounting structure of an armature and a frame of a conventional linear motor, in which (a) is a side view of the armature coil seen through, and (b) is the linear motor shown in FIG. It corresponds to a front sectional view taken along the line AA of the motor as seen from the thrust direction. The linear motor of this example is a moving coil type in which an armature is a mover, and permanent magnets for field magnets arranged on both sides of the armature via magnetic gaps are stators, and the magnetic flux penetration is performed. An explanation will be given using a mold structure. In the figure, 1
Is a linear motor, 2 is a field yoke, 3 is a permanent magnet, 4 is a yoke base, 5 is an armature, 6 is an armature coil, 7 is a winding fixing frame, 8 is a resin mold, and 9 is a frame. In the linear motor 1, a plurality of permanent magnets 3 constituting field poles are arranged linearly on the side surfaces of two rows of field yokes 2 so that the N pole and the S pole have different polarities alternately. A yoke base 4 is arranged between the yokes 2 to form a stator. Further, in the linear motor 1, the armature 5 is arranged so as to face the magnet array of the permanent magnets 3 with a magnetic gap therebetween to form a mover. The armature 5 has two rows of coreless armature coils 6 formed by forming a plurality of coil groups into a flat plate shape. The armature coils 6 are wound with a metal such as stainless steel or a resin. The fixed frame 7 is linearly arranged on both sides. Further, a frame 9 having a T-shaped cross section is provided on the upper part of the armature 5 along the longitudinal direction thereof, and when fixing the armature 5 and the frame 9, the recess of the frame 9 of the winding fixing frame 7 is provided. After the tip of the winding fixing frame 7 is inserted into 9a, the frame 9 and the winding fixing frame 7 are fixed and integrated with a resin mold 8 so as to cover the armature coil 6. A linear guide (not shown) including a slider and a guide rail is attached to the mover side and the stator side of the linear motor to move the mover linearly with respect to the stator. In such a configuration, when a current is applied to the armature coil 6 of each phase from a power source (not shown),
Electromagnetic force acts on the armature coil 6 from the magnetic field formed in the magnetic gap between the armature coil 6 and the permanent magnet 3 in the longitudinal direction of the armature coil 6 due to the electromagnetic action with the permanent magnet 3. Generates thrust to move smoothly in a straight line. At this time, when a drive current for propelling the mover flows through the armature coil 6, the armature coil 6 generates heat due to internal resistance. The heat generated in the armature coil 6 is transferred to the frame 9 through the winding fixing frame 7 and then radiated to the outside air.
