【Example】

Example 1. Embodiment 1 of the present invention FIGS. 1 to 16
It will be explained with reference to. The schematic configuration of the entire low press elevator apparatus according to the first embodiment is the same as the conventional one shown in FIG. FIG. 1 is a first embodiment of the present invention.
It is a figure which shows the iron core and winding of the primary side armature of the linear synchronous motor of the low press elevator apparatus which concerns on this, and has shown the state of the armature winding of concentrated winding.

The primary armature is laid on the side of the building over the entire length of the hoistway, but it is not very practical when actually manufactured. Therefore, as shown in FIG. B
n3, B (n + 1) 1 to B (n + 1) 3 are separated, and three-phase windings 57, U, V and W are wound in concentrated windings on each iron core 56 as shown in the figure. . In FIG. 1, the field magnet 8 on the moving side has two poles and has the same length as the iron core. Then, the U, V, and W-phase windings Un1, Un2, Un3 and Vn1, Vn2 of each iron core 56,
Vn3 and Wn1, Wn2, Wn3 are connected in series for the same excitation length Ln. In FIG. 1, the same excitation length is Bn1 to Bn3
No. 1 of the winding in Fig. 1
0, Un11, etc. indicate the winding start and winding end of each winding.
Moreover, Nn has shown the neutral point.

FIG. 2 is a view showing the relationship between the primary side armature and the magnet when the primary side armature shown in FIG. 1 is of a double sided type. The double sided linear synchronous motor armature iron of the building side is shown. It shows the state of the armature winding and the permanent magnet for field when the core unit is 2P. The armature length is the broken line portion 5 in FIG.
Two armatures Bn2 if it can be manufactured like 8,58A
L and Bn3L may be integrated.

FIG. 3 shows the relationship between the excitation length and the movable magnet of the double-sided ground primary armature. That is, it is a diagram showing the state of the armature winding and field permanent magnet of the building-side primary double-sided linear synchronous motor of the first embodiment, where the same excitation length is equivalent to three double-sided armature iron cores. FIG.

In FIG. 1, the relationship between the windings of the armatures Bn1 to Bn3, the groove tw, and the groove tw1 at the end of the iron core 56 is tw = 2 · t.
By setting w1, the armatures B (n-1) 3, Bn1 to Bn3,
Even if B (n + 1) 1 is continuously laid, the winding is symmetrical even at the joint of the armature, and low thrust ripple is possible.

FIG. 4 shows an example of connecting double electric wires when the bilateral LSM primary side armatures for propulsion of the low press elevator device shown in FIG. 24 are arranged on the left and right sides (A side, B side) of the basket. Show. The excitation block length is the three block length shown in FIG. The three blocks are connected in series, and the two-sided primary armatures are connected in parallel. There is also a method of connecting exciting coils in series between the respective exciting blocks, but the supply voltage from the inverters 16A and 16B becomes high, and it is necessary to shorten the exciting section, resulting in an increase in the number of changeover switches.

Further, FIG. 5 shows the connection of triple electric wires when the bilateral LSM primary side armatures for propulsion of the low press elevator device shown in FIG. 24 are arranged on the left and right sides (A side, B side) of the basket. Here is an example: The excitation block length is 4 blocks. The four blocks are connected in series, and the two-sided primary armatures are connected in parallel. In the case of a triple wire, the armature winding switching point becomes uniform by setting the block division to an even number as shown in the figure.

Further, FIG. 6 shows a case where the iron core of the double-sided linear synchronous motor is made longer than the magnet on the movable side. That is, it is a view in which the manufacturing unit of the iron core of the building-side primary double-sided linear synchronous motor is 4P, the left and right sides of the double-sided armature are shifted, and the seam of the iron core of the magnetic path of the movable magnet is one. In FIG. 6, the right armature 58 is integrated into three blocks.
At the center of (Bn1R, Bn2R, Bn3R), the left armature 58A,
By matching the contact points of 58B and making the excitation phases of the left and right windings the same for each of the opposing teeth, there is one seam in the armature yoke that serves as a path for the magnetic flux generated by the field on the movable side. Compared to the arrangement shown in Fig. 2 in which the seam has two points on both sides, the thrust ripple becomes smaller.

Next, the high-performance thrust ripple control when transferring the armature winding of the present invention will be described with reference to FIGS. 7 and 8. FIG. 7 is a diagram showing how the magnet on the mover side moves at the joint of the armature core, that is, the switching point of the armature excitation region. Further, FIG. 8 shows changes in the average value of the back electromotive force induced in each armature winding when the magnet on the mover side moves at the joint of the armature core, that is, the switching point of the armature excitation region. FIG.

As shown in FIG. 7, when moving from the excitation section L (n + 1) to Ln in the order of (A) → (B) → (C) → (D), the reverse generated on the armature winding side. The change in the average value of the electromotive force is as shown in FIG. When the movable magnet 8 moves from the right side to the left side in FIG. 8 at a predetermined speed, the W phase of the excitation section L (n + 1),
The counter electromotive force of W (n + 1) is ev when the counter electromotive force up to the zero point rush is ev, and the voltage is gradually reduced after the zero point rush, and becomes 0 when 0 ₁ point is reached. On the contrary, the counter electromotive force of the W phase and Wn in the excitation section Ln is 0 until the zero point rush, but after the zero point rush, the voltage is gradually increased and becomes ev when the 0 ₁ point is reached. Thereafter, as the magnet 8 moves from O ₁ → O ₂ → O ₃ , the counter electromotive forces of the V-phase and U-phase excitation sections L (n + 1) and Ln become functions of position and velocity as shown in the figure. The actual counter electromotive force waveform is a sine wave, but it is shown as an average value in FIG.

As described above, the counter electromotive force in the case of changing over the excitation section is different from that in the normal case, and shows values different in three phases as shown in FIG.

However, when switching from the excitation section L (n + 1) to Ln, the armature winding of the excitation section L (n + 1) and the armature winding of Ln are set by the inverters 16A and 16B shown in FIG. Since it suffices to pass the current Ia that requires thrust, the inverters 16A, 16A,
It is possible to easily flow the predetermined current if the gain of the current loop of 16B can be made large, but in general, the gain cannot be made large, and therefore a deviation occurs between the current command and the actual current.
Further, as the magnet 8 moves, it is necessary to supply a current to the W-phase armature winding W (n + 1) and the V-phase armature winding V (n + 1) in the excitation section L (n + 1). Therefore, if the current control for each phase is performed, it becomes unnecessary to supply an unnecessary current.

Since the negative current becomes unbalanced and the potential at the dividing point 01 fluctuates, it is necessary to suppress the fluctuation. Further, FIG. 10 is designed to eliminate the fluctuation of the division point 01, and is provided with a converter circuit 17F, a reactor 17G, transformers 17H and 17J, and a DC power source of ± 1/2 Vdc.

In this case, since the speed Vm is a linear synchronous motor, it becomes equivalent to the power supply current or voltage frequency. In this equation, the term containing φfa is due to the back electromotive force, and the term containing La is the reactance drop.

In FIG. 12, the controller 16H controls the dq

The armature reactance La90 does not change when the excitation section length changes to the same section, but the armature reactance La changes when the excitation section changes to a different area. Therefore, it is necessary for the magnetic flux φfa to change the armature reactance La according to the position signal in the transfer portion of the excitation section of the armature winding. The improved decoupling controller is shown in FIG.

In the first embodiment shown in FIG. 16, all compensation calculations and current deviation calculations are all performed at the DC level on the dq axes, but in the second embodiment shown in FIG. 17, compensation calculations and current deviations are performed. The difference is that all deviations are calculated on a three-phase alternating current. Reference numerals 121 to 126 are matching points between the current command and each armature current.

Although FIG. 12, FIG. 16 and FIG. 17 have all been described for the double electric wire shown in FIG. 26, the current control loop and the decoupling control are similarly applied to the triple electric wire shown in FIG. It can be controlled by adding one more device.
