In such position-detection sensor 6 is assembled, first, first will be mounted with in advance, second, 3rd, the 4th Hall IC 50a, 50b, 50c, the circuit substrate 55A of 50d, the foot 80a formed respectively by sensor stand 70 is inserted or be pressed in the insertion section 56 of 55B, 55C, the substrate patchhole 73 of 80b, 80c.In this condition, circuit substrate 55A, the wire connections 57 of 55B, 55C is given prominence to from baseplate part 71.
Then, will go between 100a, 100a are inserted into the through hole 58,58 of wire connections 57, are connected by scolding tin.
Then, will be integrated with circuit substrate 55A, the sensor stand 70 of 55B, 55C is from foot 80a, and 80b, 80c side is inserted in the perisporium 23 of sensor outer housing main body 20, is abutted by the protuberance 21 of baseplate part 71 with the inner peripheral surface being formed on perisporium 23.By like this, baseplate part 71 is embedded in perisporium 23, and sensor stand 70 and sensor outer housing main body 20 are integrated.
Then, will be connected each circuit substrate 55A, the many lead-in wire 100a of 55B, 55C pass slit 25 thus export to the outside of perisporium 23, make distribution guide 68 to keep via claw 24.
As Figure 11, shown in 12, circuit substrate 55A, 55B, 55C are connected respectively by wire jumper 90.
Therefore, by circuit substrate 55A, each substrate mounting of 55B, 55C is to the foot 80a of sensor stand 70, and when 80b, 80c, wire jumper 90 bends.Therefore, not to circuit substrate 55A, each substrate stress application of 55B, 55C, can by circuit substrate 55A, and 55B, 55C are configured to arc-shaped along each stator teeth 2b.
Afterwards, filler 150 (with reference to Fig. 1) is filled in the inside of perisporium 23.By like this, filler 150 and foot 80a, each substrate patchhole 73 of 80b, 80c is filled in the inner space of perisporium 23, keeps intact by placing thus sclerosis with the fixed time.
(effect)
Therefore, according to above-mentioned execution mode, by position-detection sensor 6 is configured to respectively by first, second, 3rd, the 4th Hall IC 50a, 50b, 50c, 50d is housed in three foot 80a of sensor stand 70, in 80b, 80c, can reduce the length in the circumferential direction of position-detection sensor 6.
In addition, comprise three foot 80a, 80b, 80c owing to not being in the past four, the notch part 7 being formed in the calvus 3 of each stator teeth 2b can be few.By like this, because the surface area of the stator with magnet 16 subtend increases, the total magnetic flux of stator 2 increases, and its magnetism characteristic improves.
In addition, the first, second, the 3rd, the 4th Hall IC 50a, 50b, 50c, 50d is installed in and is inserted into foot 80a respectively, and the circuit substrate 55A of 80b, 80c, on 55B, 55C.
Like this, by by first, the second, three, the 4th Hall IC 50a, 50b, 50c, 50d is as being installed in circuit substrate 55A, and the so-called chip Hall IC on 55B, 55C, does not possess lead-in wire, just can seek miniaturization.
In addition, by circuit substrate 55A, the upper installation first, second of 55B, 55C, 3rd, the 4th Hall IC 50a, 50b, 50c, 50d, by means of only by circuit substrate 55A, 55B, 55C are relative to foot 80a, and 80b, 80c press-in positions just can assemble position-detection sensor 6.Therefore, it is possible to high accuracy to first, the second, three, the 4th Hall IC 50a, 50b, 50c, 50d is arranged.
In addition, circuit substrate 55A, the foot 80a of 55B, 55C, 80b, 80c are configured along direction side by side, and are straightened setting relative to the bottom surface of transducer.Therefore, it is possible to prevent circuit substrate 55A, 55B, 55C be area occupied in radial directions.
In addition, the first, second Hall IC 50a, 50b are on identical circuit substrate 55A, and the projected direction along foot 80a is configured in coaxially.Therefore, do not need to adjust the position relationship of the first Hall IC 50a and the second Hall IC 50b in the assembling stage of position-detection sensor 6, and can not assembly error etc. be produced.In addition, can make by first Hall IC 50a export detection waveform and by second Hall IC 50b export detection waveform synchronous.
(other execution mode)
In addition, the present invention is not only defined to the above-mentioned execution mode be described with reference to accompanying drawing, it is also conceivable to the various variation in this technical scope.
Such as, by circuit substrate 55A, 55B, 55C are set as roughly in T-shaped respectively, but are not limited only to this, also can be set as being only rectangular shape etc., other shape.
In addition, in the present embodiment, the substrate of use roughly in T-shaped as circuit substrate, but is not limited only to this, adopts flexible (flexible) substrate also can as one piece of circuit substrate.
In addition, only otherwise depart from purport of the present invention, choices selection can be carried out to the structure enumerated in above-mentioned execution mode, or other structure is suitably changed.
Such as, foot 80a will be configured in respectively by collecting, 80b, each Hall IC 50a ~ 50d in 80c is set as magnetic flux passage 180a ~ 180b that the magnetic flux of magnet 16 is passed through respectively, but be configured in the place except magnetic flux passage 180a ~ 180b, configure Hall IC 50a ~ 50d respectively, and detected by the flux change of this Hall IC 50a ~ 50d to the magnetic flux passage 180a ~ 180b of each correspondence and also can.
[utilizing possibility in industry]
According to described transducer and electric rotating machine, possess four Hall IC, but foot can be set to three.By like this, the length in the circumferential direction (foot is arranged as the direction of arc-shaped) of transducer just can be shortened.Therefore, just sensor miniaturization can be made.
Engine or the generator one utilizing form as the sensor may be enumerated.That is, the sensor can be applicable to engine or generator.
