ABSTRACT = {As an energy converter, electromagnetic linear actuators (EMLAs) have been widely used in industries. Multidisciplinary methodology is a preferred tool for the design and optimization of EMLA. In this paper, a multidisciplinary method was proposed for revealing the influence mechanism of load on EMLA’s loss. The motion trajectory of EMLA is planned through tracking differentiator, an adaptive robust control was adopted to compensate the influence of load on motion trajectory. A control-electromagnetic-mechanical coupling model was established and verified experimentally. The influence laws of load change on EMLA’s loss, loss composition and loss distribution were analyzed quantitatively. The results show that the data error of experiment, and simulation result of input energy, mechanical work, and iron loss is less than 3%. The iron loss accounts for less than 54.9% of the total loss under no-load condition, while the iron loss increases with the increase of load. For iron loss distribution, only the percentage of inner yoke keeps increasing with the increase of load. The composition and distribution of loss are the basis of thermal analysis and design.},
