Research And Design Of Brushless DC Motor Measurement And Analyse System Based On USB Interface

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.
