Detailed Description
An electric motor according to an embodiment of the present invention includes: a rotor; a stator core disposed on the outer periphery of the rotor; an insulating member provided to the stator core; an aluminum winding wound around the stator core with an insulating member interposed therebetween; a power supply line for supplying power to the aluminum winding; a terminal block for arranging the power supply line; and a connection terminal fixed to the insulator, connecting the aluminum winding with the power supply line, the connection terminal including: a winding connection terminal protruding in parallel with the rotation axis of the rotor and connected to the aluminum winding; a power supply line connection terminal which is parallel to the winding connection terminal and protrudes in the same direction to connect the power supply line; and an inter-terminal connection portion that connects an end portion of the winding connection terminal on a side opposite to the protruding side and an end portion of the power supply line connection terminal on a side opposite to the protruding side so as to be able to pass electricity.
Whereby the winding connection terminals and the supply line connection terminals are independent of each other. Therefore, the galvanic corrosion prevention measure can be reliably and easily implemented to the connection portion of the winding connection terminal and the aluminum winding. This provides an effect of providing a high-quality motor.
Further, the insulating member may have a structure in which: an inner peripheral wall provided on an inner peripheral side of one side of the rotor; and an outer peripheral wall provided on an outer peripheral side opposite to the rotor, the connection terminal being provided on the outer peripheral wall.
This ensures a long distance in the circumferential direction between the winding connection terminal and the power supply line connection terminal provided on the one outer circumferential wall. Further, the motor may have a plurality of insulators, and each insulator may have an outer peripheral wall. Further, the motor may have at least 2 connection terminals on the outer peripheral walls of the adjacent insulators, respectively. This ensures that the distance in the circumferential direction between the winding connection terminal and the power supply line connection terminal provided on the adjacent outer circumferential walls is long. This provides an effect of easily increasing the degree of freedom in design and easily securing the insulation distance.
Further, the insulating material may include a housing portion for housing the inter-terminal connection portion.
Thus, the connecting terminal can be disposed in a post-step after the insulator is molded, and therefore, there is an advantage that a complicated molding die for integrally molding the insulator and the connecting terminal is not required.
Further, the structure may include a pressing member that is fitted into the housing portion in a state in which the inter-terminal connecting portion is housed, and fixes the inter-terminal connecting portion to the insulating material.
Thus, the inter-terminal connection portion connecting the winding connection terminal and the power supply line connection terminal is firmly held, thereby obtaining effects of improving the positional accuracy of the winding connection terminal and the power supply line connection terminal, facilitating the connection work with the aluminum winding and the connection work with the power supply line, and facilitating the mounting work of the terminal block.
Further, the winding connection terminal may be configured to protrude higher than the power supply line connection terminal.
In this way, in the solder connection with the aluminum winding, only the winding connection terminal can be immersed in the solder bath, and an effect of reliable and efficient electrical connection can be obtained.
Further, the terminal block may be mounted in a direction in which the winding connection terminal protrudes, and may include: a power supply line through hole through which the power supply line connection terminal passes; and a winding through hole having a diameter larger than that of the power supply line through hole and through which the winding connection terminal passes.
In this way, the winding through-hole has a margin with respect to the winding connection terminal, and therefore, it is not necessary to pay attention to the accuracy of positioning, and only the positions of the power supply line connection terminal and the power supply line through-hole need to be determined, and therefore, an effect is obtained that the operation of mounting the terminal block is facilitated.
Further, the terminal block may be mounted in a direction in which the winding connection terminal protrudes, and may include: a recess for disposing the winding connection terminal, which is opened to the outer peripheral side of the side opposite to the rotor and is recessed to the inner peripheral side of the rotor side; and a feeder line through hole through which the feeder line connection terminal passes.
Thus, the winding through-hole has a margin with respect to the winding connection terminal, and therefore, the use of the terminal is not required to pay attention to the positioning accuracy, and only the positions of the power supply line connection terminal and the power supply line through-hole need to be determined, so that the effect of facilitating the work of mounting the terminal block is obtained, and the effect of reducing the amount of resin used for forming the terminal block is obtained.
The connection terminal may be a winding connection terminal, a power supply line connection terminal, and an inter-terminal connection portion formed of a single bent wire rod and formed integrally.
This makes it possible to easily bend the connection terminal, and to reduce the material cost and the processing cost. Further, there are no connection portions formed by welding, soldering, brazing, or the like between the winding connection terminal and the inter-terminal connection portion and between the power supply line connection portion and the inter-terminal connection portion. Therefore, the possibility of disconnection of the connection terminal can be reduced.
Further, the cross section of the wire rod may be rectangular.
Thereby, the aluminum winding is firmly connected to the winding connection portion.
Further, the aluminum winding may be wound around the winding connection terminal, and the winding connection terminal may include a solder layer covering the wound aluminum winding and a heat-shrinkable tube provided outside the solder layer.
This can block the entire connection portion between the aluminum winding and the winding connection terminal from the outside air, and can reliably and easily perform an electric corrosion prevention measure.
The winding connection terminal may have an adhesive layer between the solder layer and the heat shrinkable tube.
Therefore, the shielding effect between the connection part of the aluminum winding and the winding connection terminal and the outside air is increased, and the effect of implementing reliable electric corrosion protection measures can be further improved.
Further, a structure having such a motor in the fan is adopted.
This provides an effect of extending the life of the fan, i.e., the ventilation fan, used in a high-humidity environment, for example.
Embodiments of the present invention will be described below with reference to the drawings. The following embodiments are merely examples embodying the present invention, and do not limit the technical scope of the present invention. The same reference numerals are assigned to the same parts throughout the drawings, and the following description is omitted. Further, in the drawings, the details of the portions not directly related to the present invention are omitted.
(embodiment mode 1)
Fig. 1 shows an internal structure of the motor, and fig. 2 shows a structure of an outer peripheral wall of an insulator located inside the motor. As shown in fig. 1 and 2, the motor 1 includes a rotor 2 and a stator core 3 inside a housing 25. The stator core 3 is located on the outer periphery of the rotor 2. An insulator 4 molded from resin or the like is attached to the stator core 3. The aluminum winding 5 is wound around the stator core 3 with the insulator 4 interposed therebetween. The insulator 4 includes an inner peripheral wall 4a and an outer peripheral wall 4b for holding the aluminum winding 5. The outer circumferential wall 4b is located farther from the rotor 2 than the inner circumferential wall 4 a. That is, the inner circumferential wall 4a is provided on the inner circumferential side, which is one side of the rotor 2. The outer peripheral wall 4b is provided on the outer peripheral side opposite to the rotor 2. The connection terminal 6 is fixed to the outer peripheral wall 4b on one side (upper side in fig. 1) across the stator core 3. A terminal block 13 is attached to an upper portion of the outer peripheral wall 4 b.
As shown in fig. 2, the outer peripheral wall 4b has a housing portion 14 for housing the connection terminal 6, and a holding recess 18 for engaging with the locking portion 16 of the pressing member 15. The pressing member 15 is a member for pressing the connection terminal 6 so that the connection terminal 6 is firmly held inside the housing portion 14. The connection terminal 6 is formed of a wire material formed of a copper material or a steel material. The connection terminal 6 has a winding connection terminal 7 for connection to the aluminum winding 5, a power supply line connection terminal 8 for connection to a power supply line 10, and an inter-terminal connection portion 9 for connecting the winding connection terminal 7 and the power supply line connection terminal 8.
The winding connection terminal 7 has a rod shape having a 1 st end 71 and a 2 nd end 72, and protrudes in parallel with the rotation axis of the rotor 2. The aluminum coil 5 is wound around the 1 st end 71 of the coil connecting terminal 7. Here, protruding in parallel means protruding in a parallel direction.
The power supply line connection terminal 8 has a rod shape having a 1 st end 81 and a 2 nd end 82, and protrudes in the same direction as the winding connection terminal 7. The feeder line 10 is connected to the 1 st end 81 of the feeder line connection terminal 8.
The inter-terminal connection portion 9 connects the 2 nd end portion 72 of the winding connection terminal 7 and the 2 nd end portion 82 of the power-supply-line connection terminal 8 to be electrically feedable. That is, the end (the 2 nd end 72) of the winding connection terminal 7 opposite to the end (the 1 st end 71) protruding to wind the aluminum winding 5 and the end (the 2 nd end 82) of the power supply line connection terminal 8 opposite to the end (the 1 st end 81) protruding to connect the power supply line 10 are electrically connectable by the inter-terminal connection part 9. In the present embodiment, the winding connection terminal 7, the inter-terminal connection portion 9, and the power-supply-line connection terminal 8 are formed of one bent wire rod, and they are integrally formed. The winding connection terminal 7 is substantially parallel to the power supply line connection terminal 8 and substantially perpendicular to the inter-terminal connection portion 9. The feeder connection terminal 8 is substantially parallel to the winding connection terminal 7 and substantially perpendicular to the inter-terminal connection portion 9. The winding connection terminal 7 and the power supply line connection terminal 8 extend in the same direction from the inter-terminal connection portion 9. The height of the winding connection terminal 7 and the height of the power supply line connection terminal 8 are based on the inter-terminal connection 9, and the winding connection terminal 7 is formed higher than the power supply line connection terminal 8.
The connection terminal 6 is fitted into the housing portion 14 of the outer peripheral wall 4 b. Thereby, the inter-terminal connecting portion 9 of the connecting terminal 6 is received in the receiving portion 14. The pressing member 15 is fitted into the housing portion 14 in a state where the inter-terminal connecting portion 9 is housed. The pressing member 15 is fixed to the outer peripheral wall 4b of the insulator 4 by the engagement of the locking portion 16 of the pressing member 15 with the holding recess 18 of the outer peripheral wall 4 b. Thereby, the inter-terminal connecting portion 9 of the connecting terminal 6 is fixed to the outer peripheral wall 4b of the insulator 4.
The pressing member 15 has terminal pressing portions 17 on both side surfaces thereof, and the terminal pressing portions 17 press and urge the winding connection terminals 7 and the power supply line connection terminals 8 against the inner wall of the housing portion 14, respectively, to fix the connection terminals 6 to the outer peripheral wall 4 b.
Fig. 3 and 4 are diagrams showing a processing state of the winding connection terminal 7. The winding connection terminal 7 protrudes higher than the power supply line connection terminal 8. An aluminum wire terminal portion 5a is wound around the winding connection terminal 7, a solder layer 22 is formed by soldering, and a heat-shrinkable tube 23 is covered on the outer peripheral portion thereof to perform heat treatment. At this time, it is desirable that the mouths of the heat shrinkable tubes 23 on the tip end sides of the winding connection terminals 7 are completely in close contact with each other, and if the mouths are not in close contact with each other due to only heat shrinkage, the mouths can be mechanically pressed and brought into close contact with each other. In general, the soldering process is performed by immersing the winding connection terminals 7 in a solder bath. However, the aluminum wire terminal portion 5a may be subjected to a necessary reduction treatment and then dipped, or may be welded by applying ultrasonic waves while using a dedicated solder for aluminum wire connection. In either case, it is important that the solder layer 22 be formed at a position higher than the height of the adjacent feeder line connection terminal 8. By doing so, unnecessary solder adhesion to the surface of the power supply line connection terminal 8 is avoided. Further, the adhesive layer 24 is formed on the inner layer of the heat shrinkable tube 23, and the adhesive layer 24 can be applied to the outer periphery of the solder layer 22, and the effect and action thereof are not changed even when the adhesive layer 24 is applied to the inner periphery of the heat shrinkable tube 23.
Fig. 5 is a plan view showing a state in which the terminal block 13 of the motor 1 is attached. The terminal block 13 may be molded from resin, and a printed circuit board may be used. The feeder line 10 for introducing power from the outside is fixed by a binding band 11 or the like via a protective tube 12. The terminal block 13 is mounted in the direction of protrusion of the winding connection terminal 7. The terminal block 13 is provided with a winding through hole 20 through which the winding connection terminal 7 is inserted. The size of the winding through-hole 20 is a size having a margin with respect to the maximum outer size of the heat shrinkable tube 23 applied to the winding connection terminal 7. A feeder line through hole 19 for inserting the feeder line connection terminal 8 is provided adjacent to the winding through hole 20 in the circumferential direction. The size of the feeder line through hole 19 may be the degree of insertion of the feeder line connection terminal 8. The winding through-hole 20 has a larger diameter than the power supply line through-hole 19. The margin (size of the gap) of the winding through-hole 20 with respect to the winding connection terminal 7 may be larger than the margin (size of the gap) of the power supply line connection terminal of the power supply line through-hole 19. The connection structure between the feeder line 10 and the feeder line connection terminal 8 is not shown, and may be electrically connected to the feeder line 10 through a copper foil of a printed circuit board, or may be electrically connected to the feeder line 10 directly, or an annular terminal may be attached to the tip of the feeder line 10, for example, for electrical connection.
(modification example)
As shown in fig. 6, a notched recess 21 that is open toward the outer peripheral side of the terminal block 13 and is recessed toward the inner peripheral side may be formed in the periphery of the terminal block 13 where the feeder line connection terminal 8 is located. The opening and the depression of the concave portion 21 are larger than the outer dimensions of the heat shrinkable tube 23 applied to the winding connection terminal 7, that is, a space for housing them can be secured. Further, the margin (size of the gap) of the recess 21 with respect to the winding connection terminal 7 may be larger than the margin (size of the gap) of the power supply line connection terminal of the power supply line through hole 19.
By forming the notch-shaped recess 21, an effect is obtained that the work of attaching the terminal block 13 becomes easy, and an effect is obtained that the amount of material used for forming the terminal block 13 can be reduced.
Further, as described above, the connection terminal 6 is formed of a wire material. The wire rod is preferably a material having a rectangular cross section perpendicular to the longitudinal direction of the wire rod. Thus, in the case of a rectangular shape (square shape) as compared with a circular shape, the wound aluminum wire terminal portion 5a is pressed by the corners of the wire material, and the adhesion is increased. Therefore, the looseness or looseness of the aluminum wire terminal portion 5a is avoided, and the stability of the electrical connection by the solder is improved. Further, when the housing portion 14 shown in fig. 2 is inserted into the connection terminal 6, the inner wall of the housing portion 14 is in surface contact with the connection terminal 6. Therefore, physical stability of the connection terminal 6 is improved, and contact with air is reduced, whereby the influence of corrosion on the connection terminal 6 can be suppressed.
Industrial applicability of the invention
The motor of the present invention can reliably and easily protect the connection portion between the aluminum winding and the different metal, and thus can be used as a motor for a fan of an equipment, a home appliance, or the like.
