Description of the invention (j [Technical Field] The present invention relates to an armature that can be effectively cooled, a linear motor can be suppressed to a low cost, and troubles such as maintenance caused when peripheral equipment is connected to piping and the like can be avoided Cooling device for linear motor. [Technical background] In the past, it has been used as a positioning device for the conveying mechanism of a working machine or a semiconductor manufacturing device. The armature is used as a moving element and the magnetic field pole is used to fix the element. The rotatable coil type linear motor that is relatively opposed in the long direction is shown in Fig. 6. This figure is a front sectional view of a conventional linear motor. In the figure, 3 1 is a linear motor and 3 2 is an armature. , 3 3 is the magnetic core, 3 4 is the armature installation plate, 3 5 is the permanent magnet, 36 is the yoke, 37 is the armature line, 38 is the installation screw, 39 is the refrigerant path, and 40 is the mold. In this structure, a plurality of permanent magnets 3 5 with different polarities are arranged along the longer direction (direction perpendicular to the paper surface) of the yoke 3 6 having a C-shaped cross section, and the yoke 3 6 And the permanent magnet 3 5 is constituted as a solid A magnetic core 33 formed by stacking an electromagnetic steel plate in the height direction of the permanent magnet 35 is provided through the permanent magnet 35 and the magnetic gap. The magnetic core 33 is wound with an armature coil 37 inside its groove to Moulded resin 40 fixes its surroundings, and constitutes a movable element composed of a magnetic core 33 and an armature coil 37. The magnetic core 33 and the armature mounting plate 34 are locked to the armature mounting plate 34 by the mounting screws 38 The female screw part (not shown) is screwed. In addition, the armature 32 is opposite to the armature coil 37 and is provided with a refrigerant passage 39.

Consumer Cooperatives -4- 552765 A7 __B7___ 5. Description of the invention (3 (Please read the precautions on the back before filling this page) The 39 units are fixed with molded resin 40, and the armature 32 and the refrigerant passage 39 form a unitary cooling unit. The armature mounting plate 34, but the table (not shown) is supported by linear guides, and the use of linear It can make the linear motor slide along the longer direction of the table (the direction perpendicular to the paper surface). However, the conventional technology has the following problems. In order to increase the thrust of the linear motor 31, the power from When the pivotal coil 37 continues to supply the driving current, the heat generation will increase due to the increase in temperature due to the increase in the internal resistance of the armature coil 37. Therefore, the heat of the armature coil 37 is transmitted to the refrigerant path 39 side, and the forced convection of the refrigerant is performed by the refrigerant. Heat transfer is performed for heat exchange. In addition, the magnetic core 33 increases in temperature due to the increase in loss, and the heat generation also increases. Although the heat of the magnetic core 33 is transferred to the top of the armature mounting plate 34, the heat is transferred to the top of the armature mounting plate 34. A fixed workbench (not shown), but the heat emitted from the magnetic core 33 to the outside through the workbench side is more dependent on natural convection heat transfer, which has lower cooling performance than forced convection heat transfer, and has Promote the problem of thermal deformation of the magnetic core 33 and the table. Especially the warpage in the longer direction of the magnetic core 3 3 is quite large. Printed by the Consumer Cooperative of the Intellectual Property Office of the Ministry of Economic Affairs and “heat transfer caused by heat transfer to the workbench”, it has adverse effects on linear guides or detectors (both not shown), resulting in errors in positioning accuracy. , And constitute the cause of obstacles to high-precision positioning. Due to the influence of the temperature rise of the armature coil 37, for example, when the insulation of the armature coil 37 itself is deteriorated, the cooling unit needs to be replaced corresponding to the replacement of the armature 32. In addition, the molding resin 40 covered around the armature coil 37 undergoes thermal deformation, and with the effect of the damage caused by the thermal deformation, the self-refrigerant paper scale applies the Chinese National Standard (CNS) M standard (210X297). (Centi) -5 · 552765 A7 __B7_ V. Description of the Invention (3) When refrigerant (liquid) leaks from circuit 39, corresponding to the replacement of the cooling unit, the armature 32 also needs to be replaced. Therefore, since the armature 32 and the cooling unit have an integrated structure, if any of them is damaged, all new construction is needed, which is related to the cost of the linear motor body. For example, when the above-mentioned armature has 32 liquid-cooled cooling units to form a movable element, an external pump (not shown) and a piping (not shown) connected to the pump are required, resulting in complicated and increased maintenance. It also relates to the cost of designing and manufacturing the peripheral equipment. The present invention aims to provide a cooling device for a linear motor that can improve the cooling performance of an armature at a low cost and without maintenance, in order to solve the above problems. [Invention of the invention] The present invention is a fixed element formed by a yoke having a plurality of permanent magnets with mutually staggered polarities adjacently arranged side by side, and the magnet array and magnetic properties of the permanent magnet passing through the yoke along the longer direction thereof. The gap is linearly arranged with the movable element formed by the armature of the armature line wound around the magnetic core, and the linearity of the cooling unit that can release the heat generated by the fixed element or the movable element to the outside for heat exchange The cooling device of the motor includes an armature installation plate required for installing the armature arranged in a longer direction along the top of the armature, and a heat insulation plate provided on both sides of the armature installation plate for the loading medium.

When a driving current is supplied to the armature line 7 from a power source not shown, the armature 2 generates a predetermined thrust force at the same time, and the armature coil 7 and the magnetic core 3 also generate heat. The heat is transmitted to the heat-receiving part of the cooling pipe 10 of the cooling unit 10 through the armature installation plate 4. The heat-receiving part performs intense nucleate boiling when it absorbs heat. The pressure wave caused by the intermittent nucleate boiling becomes a vibration wave The vibration of the working fluid sealed inside the heat pipe 11 is caused to vibrate, and a large amount of heat is transferred to the heat dissipation pipe 11 by the vibration of the working fluid. The heat transferred to the heat dissipation unit 11 is transferred to the cooling unit. Unit 10 is a heat-absorbing device 13 on a heat-dissipating surface side. That is, heat generated by the armature 2 is removed by a heat-radiating pipe 11 and a heat-absorbing device 13 to perform heat exchange. Moreover, by suppressing the temperature rise of the armature wire 7, it is possible to avoid all heat transfer to the armature mounting plate 4 and the insulated workbench 14 side, so as to suppress heat transfer and thermal deformation to the workbench 14.
