- a portion of the stator core 10, the insulator 6, the armature winding 2, the printed circuit board 14, and the lead wire 17 constitutes the stator 5 together with the jacket 12a.
- the outer cover 12a is formed by integrally molding the thermosetting resin 12 containing a filler, a reinforcing material, and a low shrinkage agent using an injection mold 19 in a screw type molding machine (not shown). It is formed by molding.
- fillers are aluminum hydroxide and calcium carbonate.

- the stator 5 includes a jacket 12a formed by integrally molding the armature winding 2 and the printed board 14 with the thermosetting resin 12.
- the thermosetting resin 12 contains a fibrous reinforcing material and a filler.
- the magnet rotor 3 is rotatably arranged so as to face the stator.
- the lead wire 17 is positioned away from the gate 18 so that the filling rate of the thermosetting resin 12 is slow.
- the aluminum hydroxide which is a filler of the thermosetting resin 12 has two types of particle size distribution.
- the two types of particle size distribution of aluminum hydroxide are approximately 1.5 ⁇ m and approximately 8 ⁇ m, respectively, and the particle size distribution of calcium carbonate is approximately 7 ⁇ m.
- Aluminum hydroxide accounts for 56 wt% of the entire thermosetting resin 12, and calcium carbonate accounts for 11 wt%.
- the glass fibers are 3 mm in length and 1.5 mm in length, but there are also glass fibers that break to a length of about 0.5 mm due to back pressure at the time of measurement of a screw type molding machine. .
- Each round hole 8 is filled with a thermosetting resin 12.
- Short glass fibers such as broken glass fibers and wollastonite are oriented in the thickness direction of the printed circuit board 14.
- the filler contains a large amount of fine aluminum hydroxide having a particle diameter that absorbs a large amount of the ester resin.
- the gas escape portion 13 is disposed in the vicinity of the round hole 8 of the outer cover 12a.
- Such a molded motor 1 has round holes 8 between the lands 7.
- the round hole 8 is filled with a thermosetting resin 12, and most of the glass fibers in the thermosetting resin 12 are oriented in the thickness direction of the printed board 14, and the printed board in the thermosetting resin 12 in the round hole 8.
- the molding shrinkage ratio in the plate thickness direction of 14 decreases. Therefore, it can withstand stress concentration due to molding shrinkage or the like and tensile force at the time of demolding, and interface peeling between the thermosetting resin 12 and the printed board 14 does not occur. Therefore, even when the mold motor 1 is used in a high-temperature and high-humidity space, a high-quality mold motor 1 that does not cause tracking can be realized.
- the glass fibers are oriented in the thickness direction of the printed circuit board 14 and a plurality of places where the printed circuit board 14 is connected to the front and back are formed. Accordingly, the resistance to the interfacial peeling force between the thermosetting resin 12 and the printed board 14 is increased. Therefore, even if the mold motor 1 is used in a high-temperature and high-humidity space, tracking does not occur.
- the glass fiber is oriented in the thickness direction of the printed circuit board 14, and a plurality of places connecting the front and back of the printed circuit board 14 can be formed in the longitudinal direction of the land 7. . Therefore, since the proof strength against the interface peeling force between the thermosetting resin 12 and the printed board 14 is further increased, tracking does not occur even when the mold motor 1 is used in a high-temperature and high-humidity space.
- the reinforcing material contained in the thermosetting resin 12 is made of two or more types of glass fibers.
- the fluidity of the short glass fiber is high, the amount in which the glass fiber is oriented in the thickness direction of the printed board 14 is surely increased regardless of the position of the round hole 8. That is, even if the position of the round hole 8 is located at the flow end, the flowability of the short glass fiber is high, so that the amount of the glass fiber oriented in the thickness direction of the printed board 14 is surely increased. Therefore, since the proof strength against the interface peeling force between the thermosetting resin 12 and the printed board 14 is further increased, tracking does not occur even when the mold motor 1 is used in a high-temperature and high-humidity space.
- thermosetting resin 12 contains needle-like crystals such as wollastonite having high fluidity. Since the fluidity of acicular wollastonite is high, the amount of acicular bodies oriented in the thickness direction of the printed circuit board 14 is reliably increased. Regardless of the position of the round hole 8, the needle-like body is oriented in the thickness direction of the printed board 14. Accordingly, the molding shrinkage rate in the thickness direction of the printed circuit board 14 in the thermosetting resin 12 in the round hole 8 is further reduced, so that the proof strength against the interface peeling force between the thermosetting resin 12 and the printed circuit board 14 is further increased. Therefore, even if the mold motor 1 is used in a high-temperature and high-humidity space, tracking does not occur.
- needle-like crystals such as wollastonite having high fluidity. Since the fluidity of acicular wollastonite is high, the amount of acicular bodies oriented in the thickness direction of the printed circuit board 14 is reliably increased. Regardless of the position of the round hole 8, the needle-like
- the stator 5 has a structure that is integrally molded by a screw type injection molding machine.
- the reinforcing material contained in the thermosetting resin 12 is made shorter by breaking due to the back pressure at the time of measurement of the injection molding machine. Since the broken glass fiber has high fluidity, the amount of the glass fiber oriented in the thickness direction of the printed board 14 is surely increased regardless of the position of the round hole 8. Therefore, since the proof strength against the interface peeling force between the thermosetting resin 12 and the printed board 14 is further increased, tracking does not occur even when the mold motor 1 is used in a high-temperature and high-humidity space.
- the filler contained in the thermosetting resin 12 is made of aluminum hydroxide and calcium carbonate.
- the weight percentage of aluminum hydroxide having a large amount of resin absorption is set higher than the weight percentage of calcium carbonate having a small amount of resin absorption. That is, since the fluidity as the thermosetting resin 12 decreases, the entrainment of air that occurs when the flow direction changes, such as a shape change portion when the thermosetting resin 12 flows quickly, is suppressed. Therefore, the occurrence of voids in the round hole 8 part is suppressed, and the filling amount of the filler which is an inorganic compound in the round hole 8 part is increased. Therefore, since the proof strength against the interfacial peeling force between the thermosetting resin 12 and the printed circuit board 14 is further increased, tracking does not occur even when the mold motor 1 is used in a high-temperature and high-humidity space.
- the filler has a particle size distribution of three or more types.
- the filler having a coarse particle size has a fast fluidity
- the filler having a small particle size has a slow fluidity. Therefore, it is necessary to fill the portion which needs to be filled quickly and the round hole 8 parts.
- the filling speed for the part can be adjusted. Accordingly, unfilling due to a slow filling speed and generation of voids due to a fast filling speed are suppressed.
- the filling speed in the vicinity of the round hole 8 is further reduced. Accordingly, air entrainment is suppressed and shrinkage during molding and solidification is reduced, and the resistance to the interfacial peeling force between the thermosetting resin 12 and the printed circuit board 14 is further increased. Therefore, even if the mold motor 1 is used in a high-temperature and high-humidity space, tracking does not occur.
- thermosetting resin 12 injected from the gate 18 of the injection mold 19 is filled while extruding the gasifying component such as styrene contained outside the injection mold 19, and is near the round hole 8. Filling speed and pressure are reduced. Accordingly, air entrainment is suppressed, the filling amount of the filler, which is an inorganic compound, in the round hole 8 is increased, and shrinkage during molding and solidification is reduced. Therefore, the yield strength against the interfacial peeling force between the thermosetting resin 12 and the printed circuit board 14 is further increased, and tracking does not occur even when the mold motor 1 is used in a high-temperature and high-humidity space.
- the molded motor of the present invention can be used for electrical appliances that are required to be compact, thin, and lightweight while ensuring high quality over a long period of time, such as ventilators, water heaters, and air conditioners. It can be installed in air conditioners, air purifiers, dehumidifiers, dryers, fan filter units, etc.
