ABSTRACT
The design is from the performance of Hall sensor, designed to use magnetic sensors for magnetic bearing uniformity of the testing, research, when the magnetic field uneven sensor output signal changes. In the design process using the traditional form of hardware, sampling the output signal of the most value, and show that the output changes of control in certain areas. Design a uniform magnetic field of magnetic bearing test system, and in accordance with the output to meet the requirements of the bearing samples. The system consists of signal acquisition systems, signal processing, show circuit and control circuits, and other components, through the acquisition by Hall sensor voltage signal to the amplifier will signal amplification, and then in the A / D converter after the digital signal into the microcontroller , Through the SCM software programming by the magnetic field signal, the final adoption of LED display to the magnetic field strength.
