【摘要】 无刷直流电机是一种新型的交流调速电机。本文以基于通用串行总线(USB)接口的无刷直流电机测试分析系统设计与开发为研究主题。本文对无刷直流电机测试分析系统总体结构进行了设计，其上位机采用PC机，下位机采用AT8952单片机，上下位机的通信采用USB接口。在此基础上本文进行了系统软硬件设计，其中硬件设计主要包括AT8952单片机最小系统及其外部存储器扩展设计、电参数测量接口电路设计、USB通信接口硬件设计；软件设计部分，基于Keil C进行了下位机数据采集程序设计和USB通信接口固件编程，基于VC++进行了上位机管理软件设计。在软硬件设计的基础上，本文进行了无刷直流电机测试分析系统开发，以实现对无刷直流电机进行测试和分析。该系统中，AT8952单片机作为信号采集单元，将采集到数据存放于外部RAM中，再经由USB接口传输给客户端PC机，通过ADO技术实现数据库管理，在数据处理方面充分利用Matlab强大的数据处理能力，通过Matcom实现VC与Matlab的无缝连接。系统实际运行实验验证了本文理论设计的正确性。本文的研究及其取得的成果有助于开展无刷直流电机这一新型交流调速电机的产品开发工作，对电机智能测试分析系统的研究与开发也有较好的参考价值。更多还原

【Abstract】 Brushless DC Motor (BLDCM) is a new type AC Motor Drive. This dissertation discusses mainly on measurement and assay system of Brushless DC Motor based on USB interface.The measurement and assay system of Brushless DC Motor based on USB interface is designed. It is included hardware and software. The hardware includes designing the AT8952 least system, parts of measuring electric parameters, parts of motor driver and USB communication interface. Software includes program of data collection, program of USB communication interface and program of watch and control interface based on VC.On the basis of hardware and software design, measurement and assay system of Brushless DC Motor is developed. In this dissertation, the AT8952 single chip computer is used to collect data of the motor and transmit the data to PC with USB interface, and the database is used by ADO technic. In this system, Matlab is used for data processing, and joined with VC by the Matcom. In this measurement and assay system, the parameters of Brushless DC Motor is not only measured in time, but also displayed in figure. The correctness of theory design is validated by experiment of the system.The research of this dissertation is benefit for the development of BLDCM production, and it also has better reference value for intelligent measurement and assay system of the motor.更多还原
