The magnetic pole faces of each of the PMG2 and the magnetic pole faces of the alternating current electromagnets EMGI and EMG2 are opposed to each other. A ferromagnetic metal plate, for example, a steel plate ST, is attached to the magnetic pole surface of one permanent magnet PMG2, and no steel plate ST is attached to the magnetic pole surface of the other permanent magnet PMGI. And permanent magnets PMG 1 and PMG2
As shown in the figure, the magnetic pole faces are magnetized to magnetic poles N and S, respectively. It is assumed that the permanent magnets PMG1 and PMG2 are attached to a vibrator frame (not shown).

When an AC excitation current is applied to the unillustrated coil of G2 for half a cycle and the coil is magnetized to the magnetic pole shown in the figure,
Permanent magnets PMG1 and PMG2 are moved to the left in the drawing. Meanwhile, in the next half cycle, electromagnets EMG1 and E
Since the generated magnetic pole of MG2 is reversed, permanent magnet PMG1
and PMG2 are moved to the right on the drawing. The vibrator frame is reciprocated based on this principle, but generally when an electromagnetic blower is started, that is, when the power is turned on, an excessive current flows and a strong magnetic field A, as shown in the figure, is generated.
B is a permanent magnet PMG1. It had a big impact on PMG2,
Permanent magnet PMG1. A demagnetizing effect occurs in PMG2. Therefore, the air discharge capacity of the electromagnetic blower tends to decrease.

果から、寒冷時の始動においても電磁ブロワ−の能力低
下傾向が極めて少なくなることが確認された。This tendency for air discharge capacity to decline is particularly noticeable in cold weather, for example -2
At low temperatures such as 0°C or -30°C, this becomes more noticeable due to the characteristics of the permanent magnets PMGI and PMG2. Therefore, by covering the magnetic pole surface of the permanent magnet with a steel plate ST as in the case of permanent magnet PMG2, the demagnetizing field is bypassed and the distribution area of the demagnetizing field is widened (see demagnetizing field B). The experimental results confirmed that the tendency for electromagnetic blower performance to decrease is extremely small even when starting in cold weather.

る。As shown in FIGS. 1 and 2, each of the permanent magnets 10 to 13 has a steel plate 31.32°, 33.34°,
5.36.37 and 38 are attached. Each of the above steel plates is the steel plate ST shown in the action explanation column.
In this embodiment, the electromagnet 14
This is to bypass the demagnetizing field that is intensively generated when the starting current is applied to each of the coils 17 and 15, and to widen the distribution range of the demagnetizing field. Therefore, when the steel plates 31 to 38 are attached to the respective magnetic pole faces of the permanent magnets 10 to 13, the concentration of the demagnetizing field is alleviated,
The demagnetizing effect on the permanent magnets 10 to 13 due to concentration of the demagnetizing field is alleviated. Therefore, even when starting at a low temperature when the generation of a demagnetizing field becomes obvious, the demagnetizing effect of the permanent magnets 10 to 13 is alleviated, and a decrease in the air discharging capacity of the electromagnetic blower 1 is prevented.

However, in the case of the single-circuit rated electromagnetic blowers using steel plates 31 to 38, no decrease in performance was observed even when started at -30°C.

ある。(Effects of the Invention) As described above, according to the present invention, a vibrator frame is provided in which a center disk coupled to a diaphragm of a diaphragm chamber is attached to at least one end, and a permanent magnet is attached to the vibrator frame. In an electromagnetic blower, an electromagnet is installed at a position facing the magnetic pole surface of the permanent magnet for reciprocating the vibrator frame by the action of magnetic attraction and repulsion with the permanent magnet. Since a ferromagnetic metal plate is attached to each magnetic pole surface of the magnet, there is an effect that even when starting the electromagnetic blower at a low temperature, it is possible to prevent a decrease in air discharge capacity due to demagnetization of the permanent magnet.
