Abstract: This article introduced a design for mutation signals collector of brushless DC motor based on FPGA, in hardware and software, which took FPGA as its core collection module and the core of control, ADC device as its collection module and FLASH as configuration module, which was able to effectively realize the recognition of motor signal feature in adverse working conditions. Actual test results show that the system has the characteristics of low power, small bulk, and high integration and scalability performance, meanwhile, the collector can effectively realize the feature analysis and data acquisition of the brushless DC motor signal in signal mutation environment.
