Abstract: This article introduced a design for intelligent power supply control system of the four axis brush-less motor based on FPGA. With the design of FPGA for the operation and control center of the system, which consists of the solar battery charging unit, the power drive unit, the bemf zero crossing detection unit, the voltage acquisition unit, the temperature acquisition unit and lithium polymer battery, etc. On the basis, to complete the intelligent supply and control of four axis brushless motor. The system test results shows that the intelligent charging system this paper involves has low power consumption, high reliability, good stability. At the same time, it is easy to transplant and call.
Key words: four axis brushless motor ; FPGA; intelligent charging; brushless DC motor
