The floor fan is a type of mechanical electric fan. Like other types of electric fans, the floor fan is composed of a fan head, a fan blade, a mesh cover and a control device. The fan head includes an electric motor, front and rear end covers, and a moving air supply mechanism. Wait. Different from other electric fans, the floor fan has a cylindrical bracket connected to the ground, which plays a supporting role and can be moved at any time to change the orientation. It is more convenient to use than a ceiling fan. There are shaking heads and turning pages in the floor fan. The main components of the floor fan are: AC motors. The working principle is that the energized coil is rotated by the force in the magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and at the same time, because the coil has electrical resistance, some of the inevitable electric energy is converted into thermal energy. As shown in the figure, the Great Wall FS38-40 computer controlled floor fan circuit design.
Piezoelectric Buzzer For External Drive
The piezoelectric transducers (for External Drive) produce exceptional sound output and efficiency all while meeting each customers unique performance requirements. Piezo transducers are constructed without magnets, instead they create sound mechanically via the piezoelectric effect. Our piezo transducers are not equipped with a built in drive circuit. This provides our customers with the flexibility of designing their own circuitry to meet their specific needs. The advantage of using an external drive circuit is that the piezo transducers can output sounds at multiple frequencies. Full bridge circuits ramp up SPL for more peak-to-peak voltage, making our piezo transducers a high output solution.
