FIG. 9 is a perspective view showing a so-called sirocco fan. This fan A rotating device comprising a plurality of circular fan bodies supported by a shaft and an annular body, wherein the annular body includes an iron core coil disposed along the annular body, a right-handed coil and a left-handed coil Is a coil portion that is alternately spiraled, and is provided with a first magnet portion having a magnet attached to the end of the upper circular fan body that faces the coil portion, and a lower circular shape that faces the coil portion. A second magnet part having a magnet attached to the end of the fan body is provided, and the fan body rotates in the same direction or in the opposite direction while obtaining a magnetomotive force by electric power.

A magnet part 40 in which magnet N poles and magnet S poles are alternately arranged is provided at a portion of the blade body facing the coil part, and this magnet part 40 functions as a ring-shaped magnet rotor. The upper circular blade 46 and the lower circular blade 47 are rotated in the same direction or in the opposite direction.

More specifically, the upper and lower blade bodies 46, 47 having a width of 30 cm are attached to the shaft portion having a diameter of 10 mm, and the tip portions of the upper and lower blade bodies 46, 47 are opposed to each other. A total of 20 permanent magnets with a length of 25 mm, a width of 8 mm, and a thickness of 4 mm are fixedly placed in the arming so that the N and S poles alternate, while 3 between the upper and lower blades. An iron ring core with a diameter of 3 cm and a thickness of 5 mm was provided with 20 pieces of 20 coils, each of which was wound with 1.5 巻 winding of 0.6 ø hennerel copper wire at an interval of 18 degrees.

The wings integrated with the magnet are arranged outside the coil wound around the ring-shaped iron core so that they can be freely rotated by shafts and bearings. Two coils connected in series are formed by connecting in series every 10 sections for a total of 10 sections.

Connect both ends of one coil connected in series to form a closed coil circuit. Connect the other end of the coil to the output of the switching circuit and rotate freely rotating wings. A sensor slit for position detection is provided in the shaft so that the position can be detected by an optical sensor.

Pulse power is applied at the timing when the magnet center enters the rotational direction from the coil tip in the 18 degree section. In this case, when power is supplied by converting 36 V DC voltage, the power consumption is 2 2 W. The wings rotated 1 0 0 0 0.

Since the conventional sirocco fan body has only one circular fan, the blowing power is limited. However, the sirocco fan body of this embodiment rotates two fan bodies simultaneously in the same direction or in the opposite direction. As a result, it has been confirmed that while it has more than twice the blowing power compared to the conventional fan body, the power consumption can be rotated with at least half of the conventional power. Industrial applicability

The electric rotating device of the present invention is an electric rotating device that can be easily generated by using a commercially available fan mold or blade body, and can be used as an electric fan, an electric fan, or an electric motor as an application product. It is.

In the product of the present invention, an annular iron core coil is wound around a formwork, or an air-core coil is embedded, while a plurality of permanent magnets are relatively wound on a blade body to obtain a magnetomotive force with less power. In addition, since it is not necessary to use the function as in the prior art, the entire apparatus can be reduced in weight.
