We propose a general expression to match experimental data and to extract information about the relevance of the physico-chemical mechanisms involved. We apply this analysis to three different molecular motors: bacterial flagellar motor, kinesin-1 and RNA-polymerase (Fig. 1). These motors are measured under different types of load: conservative and nonconservative. They use also different energetic sources: nucleotide hydrolysis or electrochemical potentials.
