摘 要: 结合DSP的理论学习,开发了电机转速测量的综合性、设计性实验.通过对定子线圈的电动势进行采集、频谱分析和计算,实现了对电机转速的无速度传感器直接测量. Based on DSP theory, a novel method is suggested for measuring the speed of the induction motor without speed sensor. And the comprehensive design experiment is developed. Through the collection of emf of stator and frequency spectral analysis and calculation, the direct measurement of speed for induction motor is completed without speed sensor.
