Based on FleA-field Programmable gate array, designed and implemented speed control of Brushless DC Motor (BLDCM). Designed PWM-pulse width modulation with hardware programming lan-guage-Verilog HDL. In order to design digital PID, Xilinx IP core was used. By detecting the three-phase signals of BLDCM Halls, to achieve the three-phase six-state rim. The entire system only has a single FP-GA chip, fully utilizes the powerful logic FPGA computing power, reducing overall system cost.
