Example One

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a plan view showing the overall configuration of a modular core-mounted linear motor armature according to a first embodiment of the present invention, in which a modular armature unit, a lead portion connecting unit, and a neutral point unit are disassembled.

In Fig. 1, reference numeral 1 denotes a modular armature unit, and an armature winding (not shown) of an m phase (m is an integer) made up of a plurality of coil groups is mounted on an armature core (not shown). The end has a connector structure for enabling electric power supply to the armature.

Reference numeral 2 is a lead connecting unit, reference 3 is a neutral point unit, and 4 is a pole sensor. Reference numeral 5 denotes a sub-toothed portion, and the lead portion connecting unit 2 and the neutral point unit 3 have a connector structure like the modular armature 1.

The features of the present invention differ from the prior art as follows.

That is, in FIG. 1, the terminal (connector 7) for connecting the armature winding lead is arrange | positioned at the both ends of the armature unit 1, and the armature winding is one end of the armature unit 1. A lead connection unit 2 for connecting the terminal output of the lead of the lead to the power supply from the external power source is provided, and at the other end of the armature unit 1, a neutral point unit for wiring the neutral point of the armature winding ( 3), and the lead part connection unit 2 and the neutral point unit 3 have a structure separated from the modular armature 1. And the edge part of the lead part connection unit 2 and the neutral point unit 3 has the connection structure which has the connectors 8 and 9 similarly to the edge part of the armature unit 1, respectively.

Here, FIG. 9 shows a side sectional view of a general core mounted modular linear motor.

The interior of the armature unit 1 used in this embodiment (FIG. 1) is basically the same as the linear motor of FIG. 9, in FIG. 9 divided into a plurality of armature blocks 20 and arranged in the direction of thrust. The core-mounted armature structure which is fixed on the base 24 is comprised. The block core of each armature block 20 is concentrated on the plurality of teeth 20a and the teeth 20a which are integer multiples of constants arranged at the same pitch in the longitudinal direction of the armature core made of a magnetic material. The wound armature coil 21 is provided. The armature unit 1 is disposed opposite to the stator made of the field magnetic poles 22 arranged at the same pitch on the yoke 23 and the yoke 23 via the magnetic gap.

In addition, as shown in FIG. 1, the effect of the armature unit 1 connected by the connectors 7, 8, and 9 to the lead connection unit 2 and the neutral point unit 3 is integrated. Thus, a sub-teeth portion 5 for assembling the cogging thrust generated at the teeth at both ends of the armature unit 1 is assembled.

In addition, in FIG. 1, the lead part connection unit 2 is equipped with the pole sensor 4 which detects the initial stage magnetic pole of a linear motor. In addition, when the pole sensor is not built in, the magnetic pole detection operation by software is required.

FIG. 2 is a plan view showing an example in which two modular armature units of the first embodiment are connected in series.

In FIG. 1, an example of one modular armature (an armature unit 1) is illustrated and described. In FIG. 2, a modular type configured by sequentially connecting a plurality of armature units 1 (here two) in the direction of thrust. The armature of the linear motor will be described.

That is, in FIG. 2, the terminal (connector 7) for connecting the armature winding lead is arrange | positioned in each modular armature unit 1, and the most front part of the armature group formed by connecting in the thrust direction many directions. An armature unit (1) located at is provided with a lead connecting unit (2) for connecting a terminal output of a lead of the armature winding to supply power from an external power source, and an armature unit located at the rearmost portion of the armature group. In (1), the neutral point unit 3 for wiring the neutral point of the armature winding is provided, and the lead connection unit 2 and the neutral point unit 3 are separated from the modular armature 1. .

With such a configuration, the linear motor of twice the thrust can be realized by connecting two modular armatures in series, connecting a lead part connecting unit to the front end and a neutral point unit to the rear part.

Next, the relationship between the increase in thrust and the number of parts in the case where two modular armatures in the first embodiment are connected in series can be basically expressed by the relation shown in Table 1 below.

thrust Modular armature Lead unit Neutral Unit 1x 1 unit One One Twice 2 units One One 3 times 3 units One One

As for the operation, a moving magnetic field can be generated by energizing m-phase alternating current to the lead of the armature winding in the armature unit shown in Fig. 2, but combining the armature unit with a permanent magnet field (not shown) is a synchronous motor. It operates as an induction motor when the combination of the armature unit and the field having a conductive material is substituted for the permanent magnet field.

Accordingly, the first embodiment of the present invention provides a lead connecting unit 2 for supplying power from an external power source to one end of the armature unit, and connects the neutral point of the armature winding to the other end of the armature unit 1. The neutral point unit 3 to be processed is provided, and the lead part connection unit 2 and the neutral point unit 3 are separated from the modular armature 1, and at the same time, the armature unit 1 and the lead part connection unit 2 are provided. And since each end of the neutral point unit 3 was connected by the connector, when it is necessary to arrange and arrange a plurality of modular armatures, the connection structure of the lead part connection unit 2 and the neutral point unit 3 is modular. Since the common use of parts is planned for the connection structure of the armature 1, armatures having a plurality of thrust specifications that can increase the change in thrust by using one type of modular armature can be realized. The removal of the free, and can provide a modular fittings low-cost products.

In addition, since the sub-toothed portions are assembled in the lead connecting unit and the neutral point unit, the cogging thrust generated at both front and rear ends of the linear motor can be canceled.

In addition, since the lead portion connecting unit has a built-in pole sensor portion for detecting the initial magnetic pole of the linear motor, it can be brought into a ready state when the linear motor power is turned on.

Next, FIG. 3 is a modified example of the lead portion connecting unit in the first embodiment, in which (a) shows a case where the lead protrudes to the side, and (b) shows a case where the lead protrudes upward. .

In FIG. 3, the lead part connection unit 2 has three types which protrude the extraction direction of a lead part to the front which is the thrust direction of a linear motor, or protrude in the horizontal direction or upper direction which is a direction orthogonal to the thrust direction of a linear motor. By using it, the extraction direction of the lead of the armature unit can be changed flexibly, so that space can be saved without complicating the wiring process and the cable process.

Example 2

Next, a second embodiment of the present invention will be described.

Fig. 4 is a diagram showing a plan view of a parallel lead portion connecting unit according to a second embodiment of the present invention, and Fig. 5 is a modular core to which the parallel lead portion connecting unit in the second embodiment is applied. The figure which shows the whole structure of a mounted linear motor armature, (a) is the top view which disassembled these, and (b) is the top view which combined these.

The second embodiment differs from the first embodiment in that the armature unit 1, the lead connecting unit 2, and the neutral point unit 3 are configured in n parallel arrangements (n = 2 in this example). The secondary connection unit 2 is provided with a distribution circuit (not shown) for dividing the current supplied to the lead portion connection unit 2 from an external power source (not shown) and the current divided by the distribution circuit (not shown). Terminals for connecting with each armature unit 1 are provided so as to be supplied to each armature unit 1, and the neutral point unit 3 is not shown for individually connecting end portions of the armature windings of each armature unit 1. The connection circuit and the terminal which do not have a structure are provided.

In addition, the second embodiment has a structure in which the lead portion and the modular armature unit are separated as in the first embodiment, and the parts can be shared when the thrust of the linear motor is increased.

With such a configuration, a linear motor of double thrust can be realized by connecting two modular armature units in parallel, connecting the lead unit parallel unit 6 to the front end, and the neutral point unit to the rear part.

Next, the relation between the modular armature thrust increase and the number of parts in the case where two modular armatures in the second embodiment are connected in parallel is as follows.

thrust Modular armature Lead unit Neutral Unit 1x 1 unit One One Twice 2 units 1 (2 parallel units) 2 3 times 3 units 1 (3 parallel units) Three

Accordingly, the second embodiment of the present invention can realize an increase in thrust in a direction perpendicular to the thrust direction with one kind of modular armature, so-called width direction of the modular armature.

In general, since two types of thrust expansion methods are taken in parallel and in series with one type of armature unit, productivity can be significantly improved, such as product inventory management of a linear motor and parts inventory management.

Example 3

6 is an example in which two modular coreless linear motor armatures in series according to a third embodiment of the present invention are connected in series, (a) schematically showing a front view and a side view, and (b) each armature unit. (C) is a side view which connected each armature unit.

In Fig. 6, reference numeral 11 denotes a field, and is composed of magnets 11b mounted at equal intervals so that the other poles face each other and the polarities alternately alternately inside the c-shaped field yoke 11a. .

Reference numeral 12 denotes an armature unit, and the armature unit 12 uses the armature winding formed by arranging a plurality of coil groups in the longitudinal direction of the substrate as a substrate set 12c, and the substrate set 12c. ) Is fixed on the armature base 12d to form a coreless modular linear motor armature. The front and rear ends of the armature base 12d have a connector 15 so that a plurality of armature units 12 can be connected to the connector. Reference numeral 13 is a lead protruding unit, which has a structure having a connector 16 and is connected to the front end connector 15 of the armature base 12d. Reference numeral 14 is a neutral point unit, which has a structure having a connector 17, is connected to the rear end connector 15 of the armature base 12d, and performs a neutral point connection process of the armature winding.

From such a structure, the current can flow through all the armatures through the lead projecting unit 13 regardless of the number of armatures 1, thereby making it possible to cope with all thrust specifications.

In addition, as shown in FIG. 6, when the thrust direction length of the armature 1 is represented by the electric angle, it is made into integer multiple of 360 degrees.

As a result, when the plurality of armature units 12 are connected, phase alignment between the armatures is possible only by bringing the armature base 12d into contact with the armature unit 12, thereby reducing the work time when assembling the motor to the machine. In addition, when a plurality of conventional armatures are used in connection with each other, there is a drawback that it takes time to assemble the motor to the machine because it is necessary to position the armatures at a predetermined distance. It is to solve.

Example 4

Fig. 7 is an example in which two modular coreless linear motor armatures showing a fourth embodiment of the present invention are connected in series, and (a) and (b) are side views thereof.

When the armature has a module configuration, the armature coil cannot be disposed at the connecting portion of each armature. As shown in Fig. 7A, when the armature length is an integral multiple of the electrical angle 360 °, it does not contribute to thrust generation. The space which does not become large becomes large, and the motor constant density becomes small when it sees with the whole module. On the other hand, as shown in Fig. 7 (b), when the coil arrangement is moved 120 ° or 240 ° for each armature, the connecting portion of each armature, i.e., the space not contributing to the thrust generation can be greatly suppressed. It becomes possible to prevent the fall of the motor constant density seen from the whole.

Example 5

Fig. 8 is an example of a modular coreless linear motor armature to which a parallel lead portion connecting unit showing a fifth embodiment of the present invention is applied.

6 and 7 show an example in which a plurality of armatures are connected in series, but FIG. 8A is an exploded side view of the armature unit 12, the lead protruding unit 13, and the neutral point unit 14, and FIG. The top view of (a), (c) is the side view which connected each unit of (a), (d) is the top view of (c).

By adjusting the number of armature modules, although it is possible to cope with all thrust specifications, in general, specifications such as voltage, current, or speed are often added. For example, a series connection can be selected for the current specification (○ A or less), and a parallel connection can be selected for the voltage specification (○ V or less) or speed specification (maximum speed ○ 광범위한). Compatible with the specification becomes possible.

Therefore, according to the third to fifth embodiments of the present invention, in the coreless linear motor having the characteristics of no magnetic attraction force and no cogging, and capable of low-speed ripple driving compared to the core-mounted linear motor, it is thousands to tens of thousands of N. It is possible to cope with all thrust specifications to be made by connecting a plurality of types of armature modules in series, in series or in parallel.

In addition, since parts can be suppressed with a minimum number of parts, the motor can be manufactured at a low cost and can be provided to the customer at a low price.

Industrial availability

Can be connected in series or in parallel to realize a large thrust specification, and a modular linear motor made by assembling a plurality of modular armatures can be provided. The present invention can be applied to a table transmission device, a conveying device, or the like for driving a moving table such as an electric component mounting device, a semiconductor or liquid crystal-related manufacturing device, a machine tool, or the like, which requires minute positioning at a high speed and a constant transmission speed.
