Study of the efficiency of an electronically-controlled linear escapement

The target of this paper is to develop a model of the energetic performance of an electronically-controlled linear escapement mechanism. Definitions for the evaluation of its efficiency are proposed, so as to emphasise its performance and render its understanding easily readable. Analytical modelling and the finite element method (FEM) are used to model the losses in the escapement. The results obtained with the FEM are then simplified in order to obtain a purely analytical model. Finally, experimental results are compared to the developed model.
