欠点があつた。In general, a conventional rectifier for a DC motor, as shown in Figure 1, has a capacitor installed in the slot between iron cores A and A, and the terminal C of the capacitor is connected to the edge of the common electrode plate 2. Was. However, such a conventional rectifying device for a DC motor has the drawback that it is difficult to mount the common electrode plate 2 symmetrically with respect to the axis E, resulting in poor dynamic balance.

An embodiment of the present invention will be described below with reference to the drawings.

ターの整流装置の動作について説明する。Since the electrode 3 is mounted on the shaft 8 adjacent to the commutator bar 2, it is desirable that the constant voltage diode 11 be small. One terminal 12 of the constant voltage diode 11 is connected to each of the three commutator pieces 2, and the other terminal 12 is commonly connected to the electrode a. Next, the operation of the rectifying device for a DC motor according to the present invention will be explained.

ｃは並列に接続されていることになる。One terminal 12 of the plurality of voltage regulator diodes 11 is connected to each commutator piece 2, and the other terminal 12 is connected to the electrode 3, so each voltage regulator diode 11a, llb, ll
c are connected in parallel.

オード回路にはほとんど電流は流れないことになる。Therefore, when the rectification is completed, the constant voltage diode 11 absorbs sparks and arcs. That is, in the circuit diagram of FIG. 5, a voltage V2 is applied across one voltage regulator diode 11a, and the other voltage regulator diode 11b functions as a normal diode. The circuit is the same except for the commutator, but if a voltage higher than the input voltage E is selected for V2, almost no current will flow through the constant voltage diode circuit.

に、他方の端子１２を電極３に単に半田付で接続する構
成のものに限定する主旨ではない。This V2 prevents sparks and arcs from occurring upon completion of rectification. If the direction of surge generation when the coil 10 completes rectification is in the direction of arrow A, the voltage will not rise above the Zener voltage because it is in the opposite direction to the constant voltage diode. This can prevent sparks and arcs from occurring. The rectifying device for a DC motor of the present invention is not limited to a structure in which the other terminal 12 is simply connected to the electrode 3 by soldering, as shown in the above embodiment.

効果がある。As shown in FIG. 2, three recesses 3a may be formed on the outer circumferential surface of the electrode 3, and the other terminal 12 may be fitted into the recesses 3a for electrical connection. In addition, this commutator piece 2 and electrode 3
and may be installed coaxially with each other, and an insulator 7 may be formed between them. If electrical connection is not sufficient after the terminal is press-fitted into the recess 3a, the press-contact portion of the terminal 12 may be soldered. As described above, the rectifying device for a DC motor of the present invention has electrodes installed inside the commutator pieces in the slots of the iron core, and one terminal of the surge absorbing element connected to each of the commutator pieces. Since the electrodes are connected in parallel and in rows, it is possible to prevent sparks and arcs, prevent radio wave interference, and extend the life of the electrodes. Since the terminals of the surge absorbing element are connected using this electrode as a common electrode, the entire structure can be made compact and the assembly can be simplified.
