【考案の詳細な説明】
本考案は直流電動機、特に永久磁石励磁式直流電動機の
正逆転回路に関するもので操作スイッチなどの接点を最
少限に少なくして正逆転を行なわせることを目的とした
もので゛ある。[Detailed description of the invention] This invention relates to a forward/reverse circuit for a DC motor, particularly a permanent magnet excitation type DC motor, and its purpose is to perform forward/reverse operation by minimizing the number of contacts such as operation switches. It is.
第1図、第2図、第3図、第4図は従来例の正逆運転回
路を示し、以下回路構成と問題点を順次説明する。FIG. 1, FIG. 2, FIG. 3, and FIG. 4 show conventional forward/reverse operation circuits, and the circuit configuration and problems will be sequentially explained below.
第1図は正逆転用操作スイッチのみで正逆運転を行なう
回路である。FIG. 1 shows a circuit that performs forward and reverse operation using only a forward and reverse operation switch.
端子1及び2は直流電源のプラスまたはマイナスのいず
れかに接続される。Terminals 1 and 2 are connected to either the positive or negative terminal of a DC power source.
SWは中央OFF付の正逆転用操作スイッチであり、F
側に倒されると正転側に回転し、R側に倒されると逆転
側に回転するようになっている。SW is a forward/reverse operation switch with central OFF;
When it is tilted to the side, it rotates in the forward direction, and when it is tilted to the R side, it rotates in the reverse direction.
この方式では、回路構成は簡単であるが、操作スイッチ
は中央OFF付の2回路2接点が必要であり合計4個の
接点が必要であり、スイッチとして複雑なスイッチが必
要であり、特に操作スイッチが小形であることを要求さ
れる場合に不都合を生じることがある。In this method, the circuit configuration is simple, but the operating switch requires two circuits and two contacts with a central OFF switch, for a total of four contacts, and a complex switch is required, especially the operating switch. This may cause inconvenience when the device is required to be small.
第2図は第1図とほは゛同一の他の従来例であり、操作
スイッチは正転用スイッチSWFと、逆転用スイッチS
WRの2回路に分かれている。Figure 2 shows another conventional example that is almost the same as Figure 1, and the operation switches are a forward rotation switch SWF and a reverse rotation switch S.
It is divided into two circuits: WR.
この構成ではスイッチは1組の常時開接点と常時閉接点
を持つ単純な操作スイッチでよく中央OFFの機能は不
用である特長を有しているが、2個の操作スイッチが必
要であり、操作上、その取付は位置が制限されるという
問題がある。In this configuration, the switch is a simple operation switch with one set of normally open contacts and one set of normally closed contacts, and has the advantage of not requiring a central OFF function, but it requires two operation switches, and Moreover, there is a problem in that the mounting position is restricted.
なおこの構成においては両方の操作スイッチを両方とも
運転側に倒した場合は電動機は運転されない。In addition, in this configuration, when both operation switches are turned to the operation side, the electric motor is not operated.
第3図は操作スイッチの構成を簡単にするために2個の
リレーRY1とRY2を用いている。In FIG. 3, two relays RY1 and RY2 are used to simplify the configuration of the operation switch.
正逆運転用操作スイッチSWを正転側に倒すとリレーR
Y1のコイルに通電され、接点RY、 、及びRYl、
、が閉じる結果、電動機は正転側に回転する。When the operation switch SW for forward/reverse operation is turned to the forward rotation side, relay R is activated.
The coil of Y1 is energized, and the contacts RY, , and RYl,
, closes, and the motor rotates in the forward direction.
また逆転側の場合はリレーRY2が働き、接点RY2−
1及びRY2−2が閉じ、電動機を逆転させる。In addition, in the case of the reverse side, relay RY2 works and contact RY2-
1 and RY2-2 close, reversing the motor.
この構成においては、操作スイッチは中央OFF付の1
回路2接点でよく簡単になるが、リレーは2個必要であ
り、しかも、それぞれのリレーは各2組の常時開接点が
必要であり、全体的に複雑となり不経済となる場合が多
い。In this configuration, the operating switch is one with a central OFF switch.
A two-contact circuit often simplifies the circuit, but requires two relays, and each relay requires two sets of normally open contacts, making the whole circuit complex and often uneconomical.
第4図は第3図の変形であり、操作スイッチは同じであ
るが、リレーの接点の接続構成が異なり簡単になってい
る。FIG. 4 is a modification of FIG. 3, and the operating switches are the same, but the connection configuration of the relay contacts is different and simpler.
それぞれのリレーは1組の常時開接点と常時閉接点を有
しておればよく、リレーは第3図の例より簡単であるが
、やはりリレーを2個使用している点は同じであり、複
雑であり不経済であると言える。Each relay only needs to have one set of normally open contacts and one set of normally closed contacts, and although the relay is simpler than the example in Figure 3, the point is that two relays are used, It can be said that it is complicated and uneconomical.
本考案は上記従来の欠点を解消するものであり、本考案
の一実施例を第5図に示す。The present invention solves the above-mentioned conventional drawbacks, and one embodiment of the present invention is shown in FIG.
第5図において、端子1及び2は直流電源に接続される
端子である。In FIG. 5, terminals 1 and 2 are terminals connected to a DC power source.
端子1にはリレーRYの第1の接点RY−1の常時開接
点側と、正逆転用操作スイッチSWの共通端子が接続さ
れており、端子2にはリレーRYの第1の接点RY−1
の常時閉接点側とリレーRYの第2の接点RY−2(常
時開接点)の片側端子とリレーRYのコイルの片側端子
が接続されている。The normally open contact side of the first contact RY-1 of the relay RY and the common terminal of the forward/reverse operation switch SW are connected to the terminal 1, and the terminal 2 is connected to the normally open contact side of the first contact RY-1 of the relay RY.
The normally closed contact side of the relay RY is connected to one side terminal of the second contact RY-2 (normally open contact) and one side terminal of the coil of the relay RY.
そしてリレーRYの第1の接点RY−1の共通端子は電
動機Mの片側に接続され、リレーRYの第2の常時開接
点RY−2の他端子と操作スイッチSWの逆転側接点R
とが共通にされ、電動機Mの他端子に接続されている。The common terminal of the first contact RY-1 of the relay RY is connected to one side of the motor M, and the other terminal of the second normally open contact RY-2 of the relay RY and the reverse side contact R of the operation switch SW.
are shared and connected to other terminals of the motor M.
また、操作スイッチSWの正転側接点Fと、リレーRY
のコイルの他端子が接続されている。In addition, the normal rotation side contact F of the operation switch SW and the relay RY
The other terminals of the coil are connected.
次に動作について説明する。Next, the operation will be explained.
操作スイッチSWは中央OFF付のスイッチであり、正
転側に倒すと接点F側が導通しリレーRYのコイルに通
電され、第1の接点RY−1の常時開接点及び第2の常
時開接点RY−2が閉じ、電動機Mにある極性の電圧が
印加し、正転側に回転する。The operation switch SW is a switch with a center OFF switch, and when it is turned to the normal rotation side, the contact F side becomes conductive and the coil of the relay RY is energized, and the first contact RY-1, the normally open contact, and the second normally open contact, RY. -2 is closed, a voltage of a certain polarity is applied to the motor M, and the motor M rotates in the forward direction.
次に操作スイッチSWをいったんOFFにして逆転側に
倒すと接点R側が導通し、この時リレーRYのコイルは
励磁されていないため第1の接点RY−,の常時閉接点
が導通しており、電動機Mには前と逆方向の電圧が印加
され、逆転側に回転する。Next, once the operation switch SW is turned OFF and turned to the reverse side, the contact R side becomes conductive. At this time, the coil of the relay RY is not excited, so the normally closed contact of the first contact RY-, is conductive. A voltage in the opposite direction is applied to the electric motor M, causing it to rotate in the reverse direction.
なお本説明において正転及び逆転の意味は相対的な方向
の違いを示しているのみで、ある決まった方向を示すも
のではない。Note that in this description, the meanings of forward rotation and reverse rotation only indicate a relative difference in direction, and do not indicate a certain fixed direction.
第6図は本考案の他の実施例を示す回路図でありリレー
接点の共通端子の取り方が異なるのみで動作は全く同じ
であるため詳細な説明を省略する。FIG. 6 is a circuit diagram showing another embodiment of the present invention, and since the operation is exactly the same except for the way in which the common terminal of the relay contact is arranged, detailed explanation will be omitted.
なお、第5図、6第図において、端子イはリレーRYの
第1の常時開接点の片側端子であり、端子口はリレーR
Yの常時閉接点の片側端子であり、端子ハはリレーRY

の常時閉接点の他端子であり、端子二はリレーRYの第
2の常時開接点の片側端子であり、端子ホはリレーRY
の第2の常時開接点の他端子であるといえる。In addition, in Figures 5 and 6, terminal A is one side terminal of the first normally open contact of relay RY, and the terminal opening is relay R.
This is one side terminal of the normally closed contact of Y, and terminal C is the terminal of relay RY.
The other terminal of the first normally open contact of relay RY
Terminal 2 is the other terminal of the normally closed contact of relay RY, terminal E is one side terminal of the second normally open contact of relay RY, and terminal E is the other terminal of the normally closed contact of relay RY.
It can be said that this is the other terminal of the second normally open contact.
本考案によれば、正逆転用の操作スイッチは中央OFF
付の1回路2接点の操作スイッチでよく簡単であるし、
追加したリレーは1個のみであり従来例に比し、簡単で
経済的であるという効果があり、特に操作スイッチに制
限がある場合に有効である。According to this invention, the operation switch for forward and reverse rotation is centrally OFF.
It is very easy to use with the attached 1 circuit 2 contact operation switch,
Since only one relay is added, it is simpler and more economical than the conventional example, and is particularly effective when there are restrictions on the number of operation switches.
