5図のブロック図の通りである。As described above, the present invention incorporates an encoder mechanism in a motor-directly connected fan configuration, unlike the conventional configuration in which a separately manufactured encoder device is coupled to a motor-equipped fan. As a result, the assembly process is extremely simple and the manufacturing efficiency is extremely high, without any difference from the conventional assembly process. However, during production,
First, in the case of a magnetic encoder, two magnets (5) are attached to the circumferential edge of the sub-plate (2) (or the bottom surface of the lower main plate) as shown in Figure 1. Magnets may be arranged as N and S, and a magnetic sensor (6) is placed close to these magnets, so that the rotation speed of the fan can be detected by this sensor as shown in the block diagram of Fig. 5. , and is also controlled by a feedback signal. In addition, in the optical encoder as shown in FIG. 4, light passing holes (7) are provided on the peripheral edges of the upper and lower main and sub-plates, and light emitting elements (8) are provided on one side above and below the passing holes.
On the other side, a so-called optical encoder equipped with a light receiving element 00) passes the required light beam through a hole (7) via a fixed disk.
The rotation speed of the fan is detected by receiving light through the
This is rotated and controlled using a feedback signal, as shown in the block diagram of FIG.
