摘 要:通过给定的额定点性能数据以及通过给定的空载点性能数据和额定点性能数据,分别推算永磁直流电机在其它拟用转矩工作点的电流和转速,并对推算结果与实测值进行对比。结果表明,仅通过额定点数据推算得到的值与实测值偏差较大,而通过空载点数据和额定点数据推算得到的值与实测值非常接近,偏差较小。 关键词:电机;参数;推算结果;准确度;对比分析
Abstract: Through the given rated point performance data and through the given no-load point and rated point performance datas, calculated the current and speed of the permanent magnet DC motor in other working point, respectively, and compared the calculated results and the measured value. The results show that, only through the rated data measured deviation are larger, but through the no-load point data and nominal data measured values are very close, the errors are small. Key words: motor;parameters;calculate result;accuracy;contrast and analysis
