In the present embodiment, the coil group device 30 includes three sets of coils including a U-phase coil 33a, a V-phase coil 33b, and a W-phase coil 33c. In each coil set, the U-phase coil 33a, the V-phase coil 33b, and the W-phase coil 33c are wound in a single layer and concentrated winding so as to share the teeth 35 of the yoke 31. Further, as shown in FIG. 7C, in this embodiment, the coil ends of the V-phase coil 33 b and the W-phase coil 33 c are bent toward the outside of the coil group device 30. In FIG. 7B, the coils 33a-c are shown broken away at the upper end face (in FIGS. 7A and 7C) of the yoke 31. FIG. By bending the coil ends of the V-phase coil 33 b and the W-phase coil 33 c, the area occupied by the coils 33 a-c in the yoke 31 extends along the longitudinal direction of the coil group device 30 as shown in FIG. 7B.

The guide roller 28 provided on the guide arm 27 of the magnet assembly 23a-l of the magnet assembly group 22a-d contacts the flat main surface of the exposed yoke 31 and the flat main surface of the cover member 36. Thus, the magnet assemblies 23a-l are guided along the coil group device 30. The yoke 31 and the cover member 36 of the coil group device 30 are formed of a nonmagnetic material, and the cores (iron cores) are not provided in the coils 33a-c. In the present embodiment, the occurrence of cogging generated in the magnet assemblies 23a-1 is suppressed by employing the coreless type linear motor mechanism in this way.

In the present embodiment, each coil group device 30 has an interval between adjacent coils of adjacent coil group devices 30 (in the example shown in FIG. 8, the V-phase coil 33b of one coil group device 30 and the other coil group device 30). As shown in FIG. 8, the coil group device 30 is arranged with an interval that is six times the slot pitch (= tooth pitch) s (see FIG. 7B). .

  In the present embodiment, the number of magnet assemblies 23a-1 constituting each of the first to fourth magnet assembly groups 22a-d is three. Further, the number of three-phase coil sets provided in one coil group device 30 is also three. However, in the present invention, the number of magnet assemblies constituting each of the first to fourth magnet assembly groups 22a-d may be a value other than 3, and one set of three phases provided in one coil group device 30. The number of coil sets may also be a value other than three.

  The number of magnet assemblies constituting each magnet assembly group 22a-d and the number of coil sets provided in the coil group device 30 are determined as follows. The number of magnet assemblies constituting each magnet assembly group 22a-d is “m” (m = 3 in the example shown in FIG. 2 etc.), and one set of three phases provided in one coil group device 30. The number of coil sets is expressed as “n” (in the example shown in FIG. 7A and the like, n = 3).

  As described above, the interval between adjacent magnet assemblies (interval between permanent magnets 26) in each magnet assembly group 22a-d is an odd multiple of the pole pitch τp, and thus becomes “Lτp” (L = odd). The length of the coil region in the coil group device 30 (along the longitudinal direction of the coil group device 30) is 6 ns, and the interval between adjacent coil group devices 30 is 6 s.

In the first to sixth coil arrays 61-66, one coil group device 30 is always arranged in “m−1” or more magnet assemblies 23 included in each magnet assembly group 22a-d. The following two relations need to be satisfied.
(1) Length of coil region in coil group device 30 ≧ length between “m−1” magnet assemblies (2) Length of coil region in coil group device 30 + interval between coil group devices 30 ≧ m Distance between magnet assemblies> Length of coil region in coil group device 30

When the above (1) and (2) are written using the above-described notation and the like, the following inequality is obtained.
6 ns ≧ (m−1) τp + (m−2) Lτp = 3 (m−1) s + 3 (m−2) Ls
6s + 6ns ≧ 3ms + 3 (m−1) Ls> 6ns

Arranging these inequalities gives the following inequalities:
6n ≧ 3m (1 + L) -3-6L
2 + 2n ≧ m (1 + L) −L
m (1 + L) -L> 2n

  The number “m” of the magnet assemblies constituting each magnet assembly group 22a-d and the number “n” of the three-phase one coil group provided in one coil group device 30 satisfy these inequalities. It is determined. For example, when L = 1 and m = 3, n is an integer of 2 or more. When L = 1 and m = 4, n is an integer of 3 or more. When L = 1 and m = 5, n is an integer of 4 or more. When L = 3 and m = 3, n is an integer of 4 or more. When L = 3 and m = 4, n is an integer of 6 or more. When L = 3 and m = 5, n is an integer of 8 or more.

For each car 10a-d, the operation control unit 50 is pressed by the magnet assemblies 23a-l of the first to fourth magnet assembly groups 22a-d, and any of the limit switches 38 outputs an on signal. 30 and a switching circuit 44 connected to the coil group device 30 and a switching circuit 44 connected to the coil group device 30 arranged one ahead of the moving direction of the car 10a-d with respect to the coil group device 30. An ON signal is output to the circuit 44. In addition, the operation control unit 50 outputs an off signal to the switching circuit 44 connected to the coil group device 30 other than those.

  As described above, during the lifting / lowering operation of the car 10a-d, the connection state of the coil group device 30 in which any limit switch 38 is pushed by the car 10a-d and the traveling direction of the car 10a-d. Thus, the connection state of the coil group device 30 that is one ahead of the coil group device 30 is the first connection state, and the connection states of the other coil group devices 30 are the second connection state. Each coil 33a-c of the coil group device 30 in the first connection state is excited by the corresponding inverter device 40 of the coil group device 30 and functions as a stator of the linear motor mechanism. As the position of the car 10a-d changes, the coil group device 30 in which the coils 33a-c are excited in the first connection state is sequentially switched. Since only the minimum coil group device 30 necessary for the movement of the car 10a-d, that is, the coil group device 30 in which the car 10a-d exists and the coil group device 30 that is one ahead of the coil group device 30 is energized, Energy saving operation of the cars 10a-d is realized.

  The inverter device 40 is disconnected from the coil group device 30 via the switching circuit 44 as described above after the car 10-d passes through the corresponding coil group device 30. Since the inverter device 40 does not always supply power to the coil group device 30 and the time for the inverter device 40 to supply power to the coil group device 30 is short, in the elevator device 1 of the embodiment of the present invention, the inverter device 40, a small-capacity inverter device rated for a short time (for example, about 1 minute) can be used, and the burden on cooling of the inverter device 40 and the coils 33a-c of the coil group device 30 is reduced.

  As described above, the uppermost and lowermost magnet assemblies 23a, 23c, 23d, 23f, 23g, 23i, 23j, 23l in the first to fourth magnet assembly groups 22a-d provided in the car 10a-d include A linear encoder signal detector 29 is provided, and each coil group device 30 is provided with a linear encoder reflector 37. Position information included in the reflection plate 37 is detected, in which light emitted from the signal detection unit 29 is reflected by the reflection plate 37. The operation control unit 50 specifies the position of the car 10a-d based on the detection signal sent from the signal detection unit 29 of the linear encoder. When an incremental type linear encoder is used as the linear encoder, the operation control unit 50 also refers to the number of the coil group device 30 in which the limit switch 38 is turned on in order to specify the position of the car 10a-d. The

  For example, in the specification of the position of the car 10a-d, when the car 10a-d is raised, the signal from the signal detection unit 29 in the uppermost magnet assemblies 23a and 23d in the first and second magnet assembly groups 22a-b is used. When the car 10a-d is lowered, the signal from the signal detection unit 29 in the lowermost magnet assemblies 23i and 23l in the third and fourth magnet assembly groups 22c-d is used. When these signal detectors 29 reach the empty area between the coil group devices 30, no position signal can be obtained from the signal detectors 29. In this case, the first and second magnet assembly groups when the car 10a-d rises. The signals from the signal detector 29 in the lowermost magnet assemblies 23c and 23f in 22a-b are alternatively used, and when the car 10a-d is lowered, the uppermost in the third and fourth magnet assembly groups 22c-d The signals from the signal detector 29 in the magnet assemblies 23g and 23j are alternatively used to locate the car 10a-d.

  The position of the specified car 10a-d may be, for example, the position of the permanent magnet 26 (the magnetic pole) of the magnet assembly 23a-l. The operation control unit 50 calculates the position of the permanent magnet 26 from the detection result of the signal detection unit 29 of the linear encoder and the number of the coil group device 30 in which the limit switch 38 is turned on.

  The operation control unit 50 obtains the position information of the cars 10a-d obtained as described above, a hall call signal from a hall call device (not shown) provided at each of the gates 3a-h, and the cars 10a-d. The operation of the cars 10a-d is managed and controlled based on a car call signal from a car call device (not shown) provided in the car.

The second rail segment of the rolling mechanism of the first rolling means 7a is moved to the second rail 52a and the first rolling means 7a. The first rail segment of the rolling mechanism is connected to the lower region of the first rail 51a. The descending coil row of the rolling mechanism of the first rolling means 7 a is inserted between the second coil row 62 and the third coil row 63. Since other matters of the rolling mechanism of the first rolling means 7a are the same as those of the third rolling mechanism 7c or can be understood from the description of the present specification, the description thereof will be omitted.

  The second rail 52b (which forms a pair with the second rail 52a) and the second coil array 62 provided along the second rail 52b are curved at the lower portion of the second hoistway 5b, and are formed on the wall on which the second rail 52b is provided.
