Design of Motor Speed Measurement System Based on DSP56F8346

为了实现快速准确地测量电动汽车的电动机转速,该文根据测频率周期法(M/T法)测速的原理,设计了一种基于DSP56F8346的电动机转速测量系统,并采用了新的编程方法进行实际的测量,在FreeMASTER上显示并保存测量的转速数据,取得了比较好的效果。该系统具有测速范围广和精度高等特点,便于广泛推广使用。

In order to realize fast and accurate measurement for electric vehicle motor speed, this paper introduces the speed measurement system of motor based on DSP56F8346 according to the principle of M/T, and the new programming method is used to make the actual measurement. The measured rotational speed data is displayed on FreeMASTER and saved, which has good effectiveness. The system has the characteristics of wide range of speed measurement and of high precision, it is easy to spread and use.
