提出了一种改进的电机电流特征分析（MCSA）方法，用于监控伺服驱动系统的性能，该系统仅使用一组整流器输入侧的电流传感器。本文介绍了一种数学分析，以确定如何谐波频率相关的故障从电机传播到输入逆变器，并包括直流环节组件的影响。实验结果与故障轴承的永磁伺服驱动系统，以验证所提出的方案。
A modified motor current signature analysis (MCSA) approach to monitor the performance of a servo drive system using only one set of current transducers at the input side of the rectifier is proposed. The paper introduces a mathematical analysis to determine how the harmonic frequencies related to a fault propagate from the motor to the input inverter, and includes the effect of the DC link components. Experimental results are presented for a permanent magnet servo drive system with faulty bearings to validate the proposed scheme.
