Description

Technical Field

[0001] The present disclosure relates to a rotating electrical machine.

Background Art

[0002] When a Hall element is used for detecting the rotor position and is mounted on a substrate, if a misalignment occurs during the assembly of the circuit board, the distance between the sensor position and the magnet position is shifted, resulting in variations in the characteristics of the motor. Therefore, positioning during the assembly of the circuit board and the sensor position is important.

[0003] A motor device is disclosed that suppresses misalignment during soldering by temporarily assembling a Hall IC to a substrate via a base member and press-fitting it into a case, and then soldering the Hall IC and the substrate in a state where the height and lateral direction of the Hall IC are regulated and positioned (for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in Patent Document 1, since the lead wires of the Hall IC and the substrate are directly soldered, it is necessary to mount the substrate near the Hall IC. Therefore, depending on the configuration of the motor, a first substrate and a second substrate electrically connected thereto are required, and since it is necessary to arrange the substrate near the Hall IC, there is a problem that the housing becomes large.

[0006] The present disclosure discloses a technique for solving the above problems, and an object thereof is to provide a rotating electrical machine that can accurately detect the rotational position of an output shaft and can reduce the size of the housing. [Means for solving the problem]

[Effects of the Invention]

[Modes for carrying out the invention]

[0010] Embodiment 1. Embodiment 1 relates to a rotating electric machine comprising a stator, a rotor rotatably mounted on the stator, an output shaft rotatably mounted in conjunction with the rotor, an output shaft sensor magnet and a rotation sensor for detecting the rotational position of the output shaft provided on the output shaft, a circuit board for processing the detection signal from the rotation sensor and controlling the drive of the output shaft, and a housing that holds the stator, rotor, and output shaft, and a sensor holding member that holds the rotation sensor and has signal input / output terminals electrically connected to the rotation sensor and a positioning mechanism with respect to the housing, wherein the circuit board and the signal input / output terminals connected to the rotation sensor are electrically connected by positioning the sensor holding member on the housing, and the housing comprises a first housing and a second housing, the first housing holds a first bearing that rotatably holds the shafts of the stator and rotor, and the second housing holds a second bearing that rotatably holds the shaft of the rotor and the sensor holding member, as well as rotatably holding the output shaft.

[0011] The rotating electric machine according to Embodiment 1 will be described based on Figure 1, a cross-sectional view showing the configuration of the rotating electric machine; Figures 2 and 3, perspective views showing the configuration of the sensor and sensor holding member; and Figure 4, a perspective view showing the configuration of the sensor and sensor holding member before sensor assembly. In each figure, the same or corresponding parts are indicated by the same reference numeral.

[0012] The configuration, function, and sensor holding member, which is a main component of the rotating electric machine of Embodiment 1, will be described based on Figures 1 to 4. In the following explanation, the direction along the central axis A of the rotor of a rotating electric machine is referred to as the "axial direction," and the direction of the plane perpendicular to the central axis A is referred to as the "planar direction."

[0013] First, the configuration and functions of the rotating electric machine 100 will be described based on FIG. 1. As shown in FIG. 1, the rotating electric machine 100 includes a stator 3 housed in a first housing 1 and a second housing 2, a rotor 4, a shaft 5, a circuit board 6, a rotation sensor 7, and a sensor holding member 8. The stator 3 has a winding 11 formed by winding a conducting wire through a plurality of stator cores 9 and insulators 10. The stator 3 is fixed to the first housing 1 with a plurality of screws (not shown). The rotor 4 has a rotor frame 23, a plurality of permanent magnets 24, and a rotor sensor magnet 25, and the rotor frame 23 and the shaft 5 are fixed. The shaft 5 is rotatably held by a first bearing 12 provided in the first housing 1 and a second bearing 13 provided in the second housing 2. Also, the output shaft 26 is rotatably held in the first housing 1, and is linked to the shaft 5 of the rotor 4 via, for example, a gear, and rotates about the central axis B of the output shaft 26.

[0014] The circuit board 6 is fastened and fixed to the second housing 2 with a plurality of screws (hereinafter referred to as "first screws 14"). A plurality of electronic components (not shown) for controlling the rotating electric machine 100 are mounted on the circuit board 6, and the rotation position of the rotor 4 can be detected by detecting the magnetic field of the rotor sensor magnet 25 provided on the rotor 4. Also, the circuit board 6 is electrically connected to the windings 11 and supplies current to each winding 11.

[0015] The second housing 2 includes a connector 15. The connector 15 is made of resin, and a plurality of connector terminals 16 and a bush for screwing (not shown) are integrally formed. The second housing 2 has a hole for fitting the connector 15, and the second housing 2 and the connector 15 are positioned in one direction in the axial direction and the planar direction. After the connector 15 is fitted into the second housing 2, it is fixed to the second housing 2 via a bush with a plurality of screws (not shown). Thereby, the second housing 2 and the connector 15 are fixed. One end of each connector terminal 16 is electrically connected to an external power source (not shown) and an external control device (not shown).

[0016] Also, the other end of each connector terminal 16 of the connector 15 is electrically connected to the circuit board 6 by welding. Thereby, the power of the external power source can be supplied as current to each winding 11 via each connector terminal 16 and the circuit board 6, and signal input / output with the external control device can be performed.

[0017] Also, the connector 15 has a plurality of groove portions, and a metal part 21 having a fitting portion is provided in the groove portion. Each metal part 21 may be inserted into the connector 15 and integrally formed. One end of each metal part 21 is electrically connected to the circuit board 6. Therefore, a material with good conductivity, such as copper and aluminum, can be considered for use in each metal part 21.

[0018] Next, the sensor holding member 8 will be described. As shown in FIG. 2, the sensor holding member 8 is composed of a resin part 18 having a plurality of signal input / output terminals 17 and a plurality of bushes 19. Each signal input / output terminal 17 is formed in an L shape, and the resin part 18 is formed in an L shape so as to surround each signal input / output terminal 17. One end of each signal input / output terminal 17 has a structure in which the entire surface is exposed so as to fit with each metal part 21 provided in the connector 15, and the other end has a structure in which a part is exposed because it is a connection part with the rotation sensor 7. Furthermore, one side of each signal input / output terminal 17 is exposed so that it can be positioned relative to the molding die of the resin part 18. This allows each signal input / output terminal 17 to be pressed against the molding die and positioned when the resin part 18 is molded. As a result, even if the angle of the L-shaped portion of each signal input / output terminal 17 is not stable, it can be corrected during molding, and each signal input / output terminal 17 in the sensor holding member 8 has a structure that provides high positional accuracy.

[0019] Furthermore, as shown in Figure 3, the resin part 18 is equipped with multiple resin ribs 18a. This increases the rigidity of the resin part 18 and reduces the impact of vibrations on the rotation sensor 7 and the sensor holding member 8. Furthermore, as shown in Figure 4, the resin part 18 has a sensor groove 18b for assembling the rotation sensor 7. The sensor groove 18b has a slope of 2 to 15 degrees in the insertion direction of the rotation sensor 7, resulting in a structure that facilitates the insertion of the rotation sensor 7. By fitting the rotation sensor 7 into the sensor groove 18b and welding the rotation sensor 7 to each signal input / output terminal 17, the rotation sensor 7 and the sensor holding member 8 are fixed together, and the rotation sensor 7 and each signal input / output terminal 17 are electrically connected. If welding to each signal input / output terminal 17 is insufficient to secure the rotation sensor 7, and vibration may worsen the accuracy of detecting the rotation angle of the rotation sensor 7, the rotation sensor 7 and the resin part 18 are secured by resin potting to strengthen the fixation between the rotation sensor 7 and the sensor holding member 8. Each bush 19 has a structure that protrudes axially from the resin part 18.

[0020] Furthermore, the first housing 1 has grooves that engage with each bush 19, and when assembling the sensor holding member 8 to the first housing 1, the grooves of the first housing 1 engage with each bush 19 to enable positioning in the planar direction. The sensor holding member 8 is positioned on the first housing 1 and fastened to it via bushings 19 using multiple screws (hereinafter referred to as "second screws 20"). As a result, the rotation sensor 7 is fixed to the first housing 1 with high positional accuracy via the sensor holding member 8.

[0021] The first housing 1 and the second housing 2 are positioned in the planar direction using positioning pins (not shown), and then fastened and fixed together with multiple screws (hereinafter referred to as "third screws") 22. The sensor holding member 8 is fixed to the first housing 1, and each metal component 21 is fixed to the second housing 2 via a connector 15. Therefore, when the first housing 1 and the second housing 2 are assembled, each signal input / output terminal 17 provided on the sensor holding member 8 is inserted into the mating portion of each metal component 21. Each metal component 21 elastically deforms to make contact with each signal input / output terminal 17, thereby electrically connecting them.

[0022] If the signal input / output terminals 17 provided on the sensor holding member 8 are not inserted in a position that is precisely aligned with each metal part 21, a force exceeding the elastic range may be applied to each metal part 21, potentially causing damage to each metal part 21. To prevent this, positioning pins (not shown) for positioning the first housing 1 and the second housing 2 make contact with both the first housing 1 and the second housing 2 before the sensor holding member 8 and each metal part 21 come into contact, thereby positioning them. As a result, with the sensor holding member 8 and each metal part 21 positioned via the first housing 1 and the second housing 2, each signal input / output terminal 17 is inserted into the mating portion of each metal part 21. Furthermore, although axial force is applied to each metal component 21 when each signal input / output terminal 17 is inserted, it can be inserted without any problems because it is held in place by the connector 15. The first housing 1 and the second housing 2 are fastened and fixed together by the third screw 22. As a result, the rotation sensor 7 can perform signal input and output with external control devices via each signal input / output terminal 17, each metal component 21, and the circuit board 6.

[0023] In conventional systems, a circuit board is required around the rotation sensor, and a component is needed to fix the circuit board to the first housing 1, as well as a structure to connect to external control equipment, which necessitates a larger rotating electric machine in the axial or planar direction. However, by adopting the structure of Embodiment 1, a circuit board is not required around the rotation sensor 7 by using a structure such as the sensor holding member 8 and each metal part 21 held by the connector 15, the electrical circuit can be shortened, the response of the rotation sensor 7 can be improved, and a smaller rotating electric machine can be obtained.

[0024] When power is supplied to the rotating electric machine 100 from an external power source, a predetermined current is supplied to each winding 11, and a magnetic field is generated in the stator 3. The magnetic field of the stator 3 generates repulsive and attractive forces between the stator 3 and each permanent magnet 24 of the rotor 4, causing the rotor 4 to rotate. When the shaft 5 of the rotor 4 rotates, the output shaft 26 rotates around the central axis B via a speed control mechanism (not shown). The output shaft 26 is equipped with an output shaft sensor magnet 27 at its tip, and the output shaft sensor magnet 27 rotates together with the output shaft 26. The rotation sensor 7 detects the magnetic field caused by the rotational position of the output shaft sensor magnet 27 and controls the rotation of the output shaft 26.

[0025] With this configuration, a high-performance rotating electric machine can be obtained that not only detects the rotational position of the rotor 4 using sensor components mounted on the circuit board 6, but also detects and controls the rotational position of the output shaft 26. The rotational position detection signal of the rotor 4 is used to monitor the rotational status of the rotor 4 and to confirm the integrity of the linkage mechanism with the output shaft 26.

[0026] Figure 1 shows an inner rotor type rotating electric machine where the rotor 4 is inside the stator 3. However, the same effect can be obtained by using the same configuration even for an outer rotor type rotating electric machine where the rotor 4 is outside the stator 3.

[0027] Furthermore, the mechanism for linking the rotor shaft 5 and the output shaft 26 involves a gear-shaped tip on the shaft 5 and a gear-shaped output shaft 26, which mesh with each other to transmit the rotation of the shaft 5 to the output shaft 26. Additionally, a rotating component with a different central axis can be added between the shaft 5 and the output shaft 26.

[0028] As described above, the rotating electric machine of Embodiment 1 makes it possible to realize a rotating electric machine that can accurately detect the rotational position of the output shaft and has a smaller housing.

[0029] Embodiment 2. Embodiment 2 uses press-fit connectors to connect the signal input / output terminals to the circuit board.

[0030] The second embodiment of the rotating electric machine will be described based on Figure 5, a cross-sectional view showing the configuration of the rotating electric machine, and Figure 6, a perspective view showing the configuration of the sensor and sensor holding member. In the drawings of Embodiment 2, parts that are the same as or corresponding to those in Embodiment 1 are denoted by the same reference numerals. To distinguish it from Embodiment 1, this embodiment is described as having a rotating electric machine 200, a circuit board 6A, a sensor holding member 8A, and a signal input / output terminal 17A.

[0031] The difference from Embodiment 1 is that a press fit is used to connect the signal input / output terminal 17A of the sensor holding member 8A to the circuit board 6. Note that the difference between the rotating electric machine 200 in Figure 5 and the rotating electric machine 100 in Figure 1 of Embodiment 1 is the connection between the signal input / output terminal 17A of the sensor holding member 8A and the circuit board 6. Otherwise, they are the same.

[0032] In Embodiment 1, a metal component 21 was used to electrically connect the sensor holding member 8 and the circuit board 6A. In Embodiment 2, an example in which the metal component 21 is not used will be described. As shown in Figure 6, the sensor holding member 8A is composed of a resin part 18 equipped with signal input / output terminals 17A and a plurality of bushings 19. Each signal input / output terminal 17A is formed in an L-shape, and one end has a press-fit shape at the tip. The circuit board 6A has multiple through-holes, and when the first housing 1 and the second housing are assembled, each signal input / output terminal 17A is inserted into each through-hole of the circuit board 6A, and the press-fit portion elastically deforms to electrically connect with the circuit board 6A.

[0033] By adopting this structure, the same effects as in Embodiment 1 can be obtained. Furthermore, since the sensor holding member 8A is held by the circuit board 6A, it is expected to have the effect of suppressing vibration-induced shaking, and because there is no heating process such as welding, a structure with small strain can be achieved for the circuit board 6 and the sensor holding member 8A.

[0034] As described above, the rotating electric machine of Embodiment 2 enables the accurate detection of the rotational position of the output shaft and allows for a smaller housing. Furthermore, it allows for a structure in which the circuit board and sensor holding member experience less strain.

[0035] Embodiment 3. Embodiment 3 is a sensor holding member in which the positioning and fixing bush for the first housing is located near the rotation sensor.

[0036] The rotating electric machine of Embodiment 3 will be explained, focusing on the differences from Embodiment 1, based on Figure 7, a perspective view showing the configuration of the sensor and sensor holding member. To distinguish it from Embodiment 1, it is referred to as the sensor holding member 8B.

[0037] The difference from Embodiment 1 is that the positions of each bushing 19 used for positioning and fixing the sensor holding member 8B to the first housing are located near the rotation sensor 7, that is, around the sensor groove 18b. As a result, although the volume of the resin portion 18 in the sensor holding member 8B increases compared to Embodiment 1, the effect of reducing vibrations caused by the rotation sensor 7 can be obtained.

[0038] Alternatively, one end of each signal input / output terminal 17 may be in a press-fit shape as shown in Embodiment 2, and the circuit board 6 may be provided with multiple through-holes. The terminal may be inserted into the through-holes of the circuit board 6, and the press-fit portion may be electrically connected to the circuit board 6 by elastic deformation.

[0039] As described above, the rotating electric machine of Embodiment 3 enables the accurate detection of the rotational position of the output shaft and allows for a smaller housing. Furthermore, it is possible to obtain the effect of reducing vibrations caused by vibrations of the rotation sensor.

[0040] Embodiment 4. Embodiment 4 is a sensor holding member in which the area in which the resin portion surrounds each signal input / output terminal is widened.

[0041] The rotating electric machine of Embodiment 4 will be explained, focusing on the differences from Embodiment 1, based on Figure 8, a perspective view showing the configuration of the sensor and sensor holding member. To distinguish it from Embodiment 1, it is referred to as the sensor holding member 8C.

[0042] The difference from Embodiment 1 is that the resin portion 18 of the sensor holding member 8C has a wider coverage area surrounding each signal input / output terminal 17. The thickness of the resin part 18 is increased up to the position of the resin part rib 18a shown in Figure 3 of Embodiment 1. That is, the resin part 18 surrounds everything except the tip of the signal input / output terminal 17. However, if the entire surface is increased, it becomes difficult to position each signal input / output terminal 17 in the molding die, so the resin part 18 has resin part terminal grooves 18c around the ends of each signal input / output terminal. Note that the resin part terminal grooves will be referred to as terminal grooves as appropriate. This makes it possible to maintain the positional accuracy of each signal input / output terminal 17 when insert molding the resin part 18. In Embodiment 4, the rigidity of the resin part 18 is further increased, reducing the impact of vibrations in the sensor holding member 8C.

[0043] Alternatively, one end of each signal input / output terminal 17 may be in a press-fit shape as shown in Embodiment 2, and the circuit board 6 may be provided with multiple through-holes. The terminal may be inserted into the through-holes of the circuit board 6, and the press-fit portion may be electrically connected to the circuit board 6 by elastic deformation.

[0044] As described above, the rotating electric machine of Embodiment 4 enables the accurate detection of the rotational position of the output shaft and allows for a smaller housing. Furthermore, the rigidity of the resin part can be further increased, reducing the impact of vibrations in the sensor holding member.
