Description of the invention 0) [Technical field to which the invention belongs] The present invention relates to a capacitor motor (capacitor motor) started using a capacitor (capacitor motor) 0 [Previous technology] For example Fan drive motors for air duct fans have been using capacitive induction motors since ancient times. This type of motor contains a stator and a rotor 'inside a motor frame having a cylindrical shape, and a capacitor is externally installed outside the motor case. It is constituted by electrically connecting to a winding wire wound around the stator core, and drawing it from the opening provided in the motor case to the outside, and connecting it to the capacitor and the power line. However, a configuration in which such a capacitor is arranged outside the motor housing will cause the structure of the entire motor to become larger. In addition, the wires connecting the windings and the capacitors will be lengthened, which will make the wiring work complicated. Therefore, there has been an urgent need for capacitors to be housed in a motor case together with a stator or a rotor to reduce the size thereof. [Problems to be Solved] However, when the capacitor is housed in a motor case, the capacitor is easily affected by the heat generated by each part of the motor when the motor is driven. Due to the low heat-resistant temperature of conventional capacitors, there is a problem that a motor composed of a capacitor contained in a motor case can only be applied to a low-power type having a small amount of heat.

Description of the invention (2) (Please read the precautions on the back before filling out this page.) In view of this, the purpose of the present invention is to provide a capacitor-driven motor with a capacitor that can be stored in a motor housing together with the stator and rotor. Can correspond to high-power type motors with large heat generation. [Means for Solving the Problem] The first item of the scope of patent application of the present invention is a motor provided with a driving capacitor and a stator and a rotor provided in a motor housing. A heat-resistant film in which the sum of the thermal contraction rate in the longitudinal direction and the thermal contraction rate in the width direction under C is 4% or less constitutes a dielectric of a capacitor, and the capacitor is provided in a motor case. According to the above configuration, the thin film constituting the dielectric has a small thermal contraction rate and does not easily fold at high temperatures. Therefore, it is possible to make a capacitor superior to heat resistance. Therefore, even if it is a high-power type motor having a large amount of heat, a capacitor can be arranged in the motor case. In this case, the heat-resistant film is composed of a polypropylene (PP) film, a polyphenylene sulfide (PPS) film, and a polyethylene 2,6 naphthalate (P EN) film that is superior to heat resistance. At least one of them should be printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition, the above capacitor should be a cylindrical element having a heat-resistant film provided with a group of vapor-deposited electrodes laminated and rolled up. Furthermore, terminal-connecting electrodes are provided at both ends of the element, and the vapor-deposition electrode provided in at least one of the heat-resistant films is constituted by a plurality of independent electrode portions. This paper size applies to China National Standard (CNS) A4 (210 X 297 public love) ~ 483217 Λ7 B7 V. Description of the invention (3) (Please read the precautions on the back before filling this page) If you follow the above structure, even When the vapor-deposition electrode is destroyed, a vapor-deposition electrode composed of a large number of electrode portions will cause its electrode portions to be sequentially destroyed. Therefore, compared with the case where the vapor-deposited electrode is destroyed at the same time, the destruction energy (energy) can be reduced to make it better than the safety. In addition, it is preferable to impregnate a capacitor-type impregnating agent having a softening temperature of about 1,000 to 125 t in the capacitor element. According to this structure, the impregnating agent does not dissolve from the element even at a high temperature, so that the insulation performance between the vapor-deposited electrodes can be maintained. It also has the effect of preventing damage to the electrodes caused by corona discharge due to high voltage. Furthermore, it is preferable to connect the capacitor to the winding of the stator in the motor case, especially when a terminal block or a wiring board is provided in the motor case, so that the capacitor is provided in the terminal block. Or a wiring board is preferred. With the above configuration, the connection between the capacitor and the winding can be easily performed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, the capacitors are preferably mounted on the terminal block or wiring board in a state covered by potting material. In this case, the capacitors and The connection part between the windings of the stator is also preferably covered with the above-mentioned packaging material. With the above configuration, moisture can be reliably prevented from entering the capacitor.

Generally, if the heat of about 120 ° C acts on the above-mentioned capacitors, it will make the constituent dielectric. The film shrinks in the length and width directions to produce local bulging or recesses, which deform the flat-shaped element into a cylindrical shape. The deformation amplitude of such a device varies depending on the thermal shrinkage. Therefore, depending on the size of the thermal shrinkage, the material covered with the capacitor 1¾ will often not be able to adapt to the deformation of the component, causing the packaging material to crack or crack, which may result in a decrease in water resistance. In addition, if the first and first films are contracted in the width direction, the terminal connection electrode is peeled from the first and second vapor-deposited electrodes, and the capacitor capacity t paper size is applied to the CNS A4 standard (21G χ 297 public love) 7 ^ 4-" ~--483217 Λ7 _____B7 V.

In addition, when the first and second films shrink, a displacement will occur between the first and second vapor deposition electrodes, or pleats will be formed in the first and first films to form a pm hole, or a space will be formed. It may cause a reduction in insulation. If various phenomena such as the above-mentioned component deformation, cracking of the packaging material, degradation of insulation, and change in capacitor capacity occur, the quality of the capacitor will be degraded. Therefore, in the embodiment, in order to prevent the deterioration of the capacitor as much as possible, the sum of the thermal shrinkage rate in the length direction and the thermal shrinkage rate in the width direction when heated at 120 ° C for 15 minutes is less than 4%. The first and second films 36 and 38 are preferably formed with a film of 3% or less. The thermal shrinkage of the film is calculated by the method described below.

Among them, "0" represents good, "△" represents a phenomenon that does not cause a problem, and "X" represents a decrease in quality. In addition, the sum of the heat shrinkage in the length and width directions is 5%. The reason why the film is evaluated as "△ ~ X" for "cracking" is that it has both the case where the packaging material will crack (△) and the case where the packaging material will crack (X). Printed in Figure 8 by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. It can be seen from Figure 8 that a film capacitor using a total thermal shrinkage of 5% in the length direction and the width direction has a low evaluation of all items. The quality of the device will decrease. However, when a film capacitor with a total thermal shrinkage of 4% in the length and width directions is used, the items for "deformation of the element", "decreased insulation", and "capacity change" are " "No problem", and the evaluation of "cracked" items is "good" 16 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love) Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Consumer Cooperatives 483217 A7 ____B7___ V.

Therefore, in this embodiment, the first and second films 36 and 38 are formed by using a P P film having a sum of the thermal shrinkage of the longitudinal direction and the width direction of 4% or less, preferably 3% or less. According to the above structure, the following effects can be obtained. First, because the film with small thermal shrinkage and pleating is not good at high temperatures, the first and second films 36, 38 are formed. Therefore, the quality of the capacitor 24 can be stabilized even at high temperatures, and the capacitor 2 can be improved. 4 heat-resistant temperature. Therefore, even if the electric motor 1 is a high-power electric motor 1 that generates a large amount of heat, the electric motor case 2 can house the capacitor 24. In addition, in the motor 1 described above, since the capacitor 24 is housed in the motor case 2, it is not necessary to secure a space required for the capacitor outside the motor case 2. Furthermore, in this embodiment, the capacitor 24 is arranged on the terminal block 12 so that the capacitor 24 can be connected to the winding 6 of the stator 4. Therefore, it is conventionally adopted in the motor case.

In addition, in this embodiment, a plurality of independent electrodes b 1, b 2,... Constitute the second vapor-deposited electrode 37 of the capacitor 24. Therefore, if the second vapor-deposited electrode 37 is damaged, each electrode can be destroyed one by one.

In addition, the softening temperature of the components of the capacitor 24 mentioned above is approximately (please read the precautions on the back before filling this page) 1 〇〇 ～ 1 2 5 ° C wax impregnated. Therefore, the impregnating agent does not easily flow out of the element 40 even at a high temperature, and the insulation performance between the first and first vapor-deposited electrodes 35, 37 can be maintained. Further, "in this embodiment", the above-mentioned capacitor 24 is arranged in the motor case 2 at a position corresponding to the winding 6. Therefore, the positional relationship between the capacitor 24 and the winding 6 can be kept constant, so that the temperature condition of the capacitor 24 can be kept constant. In addition, the capacitor 24 is isolated from the winding 6 so that the capacitor 24 is not easily affected by the heat generated by the winding 6. For this reason, the above-mentioned motor 1 can also cope with B-type insulation having a high insulation level. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs In addition, the capacitors 24 are mounted on the terminal block 12 in a state covered by the packaging material 26. Therefore, even if the component 40 is directly mounted on the terminal block 12 described above, the capacitor 24 can ensure the same quality as a general capacitor constructed by accommodating the component in a box. In other words, the capacitor 24 described above makes it possible to eliminate the need for a box, and therefore, it is expected to reduce the cost equivalent to that portion. Furthermore, since the terminals 25a, 25b and the capacitor mounting portion 18 of the capacitor 24 are also covered with the packaging material 26, moisture can be prevented from entering the capacitor 24, and the reliability of the capacitor 24 is further improved. In addition, the capacitor 24 is disposed in the portion of the motor housing 2 on the anti-load side, so that the connector portion 22 of the terminal block 12 and the paper size are in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -18- 483217 A7 B7 V. Description of the invention (16) The connection between the power cables can be made through the opening 11 of the motor case 2.

Also, 'the connector part 2 2 is provided on the terminal block 12 with the opening part 1 1 facing the motor case 2', so the connector part 2 2 Plug in the connector part that is connected to the power line to connect the capacitor 2 4 to the power line easily. Figures 9 and 10 show the second embodiment of the present invention, and only the differences from the first embodiment will be described below. In addition, the same parts as those in the first embodiment are assigned the same reference numerals. As shown in Fig. 9, a terminal block 48 is provided in the motor case 2 on the anti-load side portion instead of the terminal block 12 described above. The capacitor 45 is fixed below the terminal block 48. In this case, the capacitor 45 is spaced apart from the above-mentioned winding 6 and is disposed at a position radially inward of the above-mentioned winding 6. As shown in Fig. 10, the capacitor 45 has a structure in which a case 46 is filled with the above-mentioned element 40 and a packaging material 47 made of epoxy resin to cover the above-mentioned element 40. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in the second embodiment configured as described above. Since the capacitor 4 5 is arranged in the motor case 2 in a wider portion on the radial side than the winding 6, Therefore, the disadvantage of increasing the volume of the motor case 2 in the axial direction caused by accommodating the capacitor in the motor case 2 can be suppressed as much as possible.

That is, in the present invention, the terminal block 48 is not provided in the motor case 2, and the capacitor 45 is fixed to the upper portion of the winding 6 by the fixing wire 45. Therefore, in this embodiment, the above-mentioned capacitor 45 is in contact with the winding 6. However, since the motor 1 of this embodiment belongs to type A insulation, it does not cause a problem. In this case, one end of the main winding 6a and the lead 51 are connected to one terminal 25a of the capacitor 45, and one end of the auxiliary winding 6b is connected to the other terminal 2b. In addition, although not shown, the lead wire 52 is connected to the other end portion of the main winding 6a and the other end portion of the auxiliary winding 6b. These lead wires 51 and 52 are led out of the motor case 2 through the opening 11 of the motor case 2 described above, and are connected to a power cord (not shown). Fig. 12 shows a fourth embodiment of the present invention, which is different from the third embodiment in the following points. That is, the capacitors 4 5 are arranged above the stator 4 via the capacitor installation member 5 3. In this case, a space of a distance D is maintained between the capacitor 45 and the winding 6. According to this structure, the capacitors 45 can be made less susceptible to the influence of the heat generated in the windings 6, and therefore, the above-mentioned motor 1 can be applied to an insulation level that allows the highest temperature to be high. According to the present invention, the present invention is not limited to the above embodiments.

In addition, the above-mentioned PP film, PPS film, and PEN film may be used in an appropriate combination under consideration of issues such as dielectric constant, thermal shrinkage, or self-heating. ° It may be used separately depending on the application of the motor . The capacitor may be arranged on a wiring substrate instead of being provided on a terminal block. Instead of providing a connector section, a component (S L terminal) for holding a power wire (such as a V V F cable) may be provided on the terminal block. In this case, the SL terminal may be integrally formed with the terminal block, or may be formed separately from the terminal block. According to the above configuration, since the power cord can be directly connected to the terminal block, the motor installation work can be easily performed. ----------; Install --- (Please read the precautions on the back before filling out this page) m Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper applies Chinese National Standard (CNS) A4 Specifications (210 X 297 mm) -21-
