Description of the invention (1) The present invention relates to the coil used by the modular material module made of electrically insulating synthetic resin Modularized motors (modular motors) that have been formed. Most of the motors used in the blower fans of conventional household air conditioners, such as those shown in Japanese Shikaihei No. 5-2553 (H02K3 / 44), of which the stator core and coil (stator coil ) It is integrally formed by fixing (moduleizing) thermosetting resin (modular material) with electrical insulation (hereinafter referred to as modularized motor). And 'when excessive current flows through the above-mentioned modular motor, abnormal heat will be generated, causing burn-out or sparks, or even causing fire and other problems'. Therefore, such a modular motor must be installed As described in the aforementioned gazette, as a heat-sensitive protector for protection of heat-sensitive elements. This thermal protector is constructed by enclosing a bimetallic contact in a rectangular resin box with a bottomed cylinder. The size of the resin box must match the size of the modular motor itself. The usual dimensions are 3.9 legs high, 15.5 legs long, 7.3 mm wide, and 0.9 mm thick. Therefore, the heat-sensitive protector can be integrated into the modular material of the modular motor, or as shown in the aforementioned gazette, the method of installation by inserting it into a storage recess formed in advance during modularization . In this way, the abnormal heating of the coil is used to cause the bimetal to operate to perform protection operations such as power off. However, the conventional thermal protector is made of polybutylene terephthalate because the resin box is molded. When integrated into a modular material, the temperature due to modularization will be generated. .The paper size of the resin box changed by pressure is applicable to the Chinese national standard (.CNS) A4 specification (210X2.97mm) -----'-- ^ ---- 1 ------ order- ----- force_ (please read the notes on the back before filling this page) A7

Description of the invention (8) 52. Wires 59, 60 and polyphenyl ether broken respectively on the arm 54 and the board 55 Resin insulation components 56, 57 and epoxy resin encapsulation material 58 etc. The size of the resin box 50 is 3.9 legs high, 15.5 legs long, 7.3 legs wide, and 0.9 mm thick, and its material is made of polystyrene Molded by sulfur bond resin. The thermal deformation temperature of this polyphenylene sulfide is above 260 ° C at a pressure of 18.6 kg / cm2, and the flow length at a temperature of 320 ° C and a pressure of 1000 kg / cm2 is 120 mm. When molding the resin box 50, the middle mold 63 is inserted between the upper mold 61 and the lower mold 62 as shown in FIG. 10, and the space formed by these The nozzle 66 is filled with polyphenylene sulfide melted in the cylinder 67. At this time, the pellets of the polyphenylene sulfide are pre-dried at 140 ° C for 3 hours in the front section of the cylinder 67. The side is 290 ° C ~ 300 ° C, the nozzle side of the cylinder 67 is 310 ° C, the temperature of the nozzle 66 is controlled at 310 ° C ~ 320 ° C. The temperature of each mold 61 ~ 63 is controlled at 150 ° C, and The injection pressure is 50 ~ 70kgf / cm2. At this time, since the flow length of the polyphenylene sulfide as mentioned above is 120 mm at a temperature of 320 ° C and a pressure of 1000 kg / cm2, the temperature and pressure as described above Under molding, the molten resin material is injected into the entire mold for high-precision molding. After the resin is injected, the molds 61 to 63 are cooled, and after the polyphenylene sulfide solidifies, the resin box 50 is taken out of the mold. After that, Insert the wires 59, 6 connected to the aforementioned arm 54, bimetal 53 and movable contact 51, plate 55 and fixed contact 52, insulating components 56, 57, arm 54 and plate 55 into this resin 11 This paper size is applicable China National Standard (.CNS) Α4 specification (210Χ297mm) ---- ^-^ --- j · ------ lτ ------ i *-(please Read the precautions on the back and then fill out this page) A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Instruction for invention (9) Inside the box 50, with the wires 59 and 60 pulled out, it is sealed by the packaging material 58 In combination, the heat-sensitive protector S is completed. In addition, polyphenylene sulfide often contains fillers such as glass-woven fabrics. In addition, if trace amounts of corrosive gas are generated during molding, the mold material used must have both wear resistance and corrosion resistance. As shown in Fig. 11, such a modular motor M series is equipped with an insulator 2 and combined into a ring shape, and at the same time, a stator core 1 equipped with a wire coil 3, printed circuit boards 12A, 12B is fixed to In the mold composed of the upper mold 29 and the lower mold 30, a modular material composed of unsaturated polyester is injected through two injection ports 31 to modularize the stator A. The modular temperature at this time is 160 ° C. The pressure is 70 kg / cm2. When the synthetic resin is injected, the retaining pin 27 protruding from the upper mold 29 (by this is formed inside the outer frame 4 as shown in FIG. 3 The hole 28A in the middle) abuts the abutment portion 28 of the printed circuit boards 12A and 12B to keep the printed circuit boards 12A and 12B at a predetermined position, thus preventing the position of the printed circuit boards 12A and 12B from moving and deforming, and can be at a predetermined position The printed circuit boards 12A and 12B are cured together with the stator A. In addition, the modular material is adhered and cured on the surface of the resin case 50 of the thermal protector S, and the resin case 50 is a polyphenylene terephthalate polystyrene polystyrene with a heat distortion temperature higher than that of the conventional one. The sulfide is molded, so even if it is integrated into a modular material at the above-mentioned pressure, the deformation of the resin box 50 produced is zero or extremely small. Therefore, the deflection of the thermal protector S itself can be eliminated, and erroneous operation can be prevented. This is through the experiment of inserting the stator A in the modular state into the oven (the operating temperature of the bimetal 53 is 12) The paper size is applicable to the Chinese national standard (CNS> A4 specification (210X29 * 7mm)). !--HH 1-^ — ^ 1 1 ^ Private-........-----=-· ----- 1 OJ (Please read the notes on the back before filling this page ) A7 A7 B7 printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5.

In particular, it is not necessary to be modularized as usual It is covered with a protective layer made of steel plate, which can significantly simplify the installation work. Next, Figure 9 shows the circuit diagram of the modular motor M. 3M, 3A are the main coil and the auxiliary coil constituting the coil 3 (stator coil), It is connected to the commercial alternating current AC through the thermal protector S and bidirectional triode (TRIAC) 63 of the present invention. The gate of this TRIAC 63 is controlled by the controller 64, which is used to observe The output of the aforementioned Hall element H for the number of rotations is connected. In addition, the capacitor 62 is connected in series to the auxiliary coil 3A. The operation described above is explained. In the normal state, the movable contact 51 of the thermal protector S is in contact with the fixed contact 52 as shown in Fig. 8. The TRLAC 63 is activated by the controller 64 to make the current The rotation of the rotor B is started through the main coil 3M and the auxiliary coil 3A. The controller 64 is an on-time controlled based on the output of the Hall element H to control the number of rotations of the modular motor M. Therefore, when the rotor B is Locked, etc. so that excessive current flows through the coil 3 (3Μ, 3Α), and abnormal heat generation occurs, the bimetal 53 will act to move the arm 54, so that the movable contact 51 and the fixed contact 52 from the figure The state of 8 becomes separated from each other. By this, the current to the coil 3 is interrupted, and the rotation of the modular motor M is stopped. At this time, since the thermal protector S abuts on the coil 3, and has Excellent thermal conductivity, so the bimetal 53 can perform high-precision operations. In addition, the embodiment is based on the premise of an induction motor, but it is also applicable to straight 13 paper standards apply China National Standards (CNS) Α4 specifications (210 Χ (297 mm)
