摘要

阻尼式机电变换器是各种机电系统的执行元件，其技术状况直接影响到整个系统的可靠性。因此，对其设计提出了很高的要求，有必要对其技术状况进行诊断。最有希望的诊断方法是使用仪器分析外部磁场的方法。此外，外磁场的评价与阻尼式机电变换器磁兼容的实际验证有关。为此，作者建立了具有一次磁场不对称的阻尼式机电能量变换器的外磁场数学模型，并考虑了利用外磁场进行诊断的可能性。仿真结果分析表明，磁场对称轴相对于磁系轴的相对位移可以通过计算确定，并以外磁场强度(包络线)幅值变化的形式作为诊断信号。

The external magnetic field of damping electromechanical energy converters

Damping electromechanical energy converters are the executive elements of various electromechanical systems and their technical condition affect the reliability of the whole system. Therefore, high demands are placed on its design and there is a need to diagnose its technical condition. The most promising method of diagnosis is the method using an instrument analysis of an external magnetic field. In addition, the evaluation of the external magnetic field is relevant in practical verification of the magnetic compatibility of damping electromechanical energy converters. In this regard, the authors developed a mathematical model of an external magnetic field of damping electromechanical energy converters with primary magnetic field asymmetry and considered the possibility of diagnosing them using an external magnetic field. The simulation results analysis showed that the relative displacement of the magnetic symmetry axis of the field from the magnetic system axis could be determined by calculation and as a diagnostic signal in the form of changes in the amplitude of the external magnetic field intensity (envelope).
