配备有微型直流电机的动态状态机电设备的特征在于在其大部分工作寿命期间的粘滑运动。深入分析所有不同摩擦部件的作用，是在此类机电一体化应用中进行精确设计的特权。本文认为，经典的直流电机表征模型的重估，通过不同的方法，基于一个共同模拟多物理场数值模型，并通过不同的分析的内部摩擦现象。该模型是通过一种新的评价方法的机械和电气性能，分别通过多体分析和等效电路模型分析。运动学和动力学响应，以及由数值联合仿真模型获得的电吸收参数的估计，验证通过间接的实验测量从两个微型直流电机，不同的尺寸和性能，并与不同的电压供电。
Dynamic regime mechatronic devices equipped with micro-DC-motors are characterized by a stick-slip motion during the majority of their working life. An in-depth analysis of the contribution of all the different friction components represents a prerogative for an accurate design in such mechatronic applications. The paper considers a revaluation of the classic DC-motor characterization model, through a different approach based onto a co-simulation multi-physics numerical model and through a different analysis of the internal friction phenomena. The model is developed through a novel evaluation approach of the mechanical and electrical behavior, respectively through a multibody analysis and an equivalent circuit model analysis. The kinematic and dynamic responses, as well as the estimation of electrical absorption parameters obtained by the numerical co-simulation model, are validated through indirect experimental measurements obtained from two micro-DC motors, different in dimensions and performances and powered with different voltages.
