We analyze the dynamics of driven translations or rotations based on models with internal oscillations. In particular we discuss several new mechanisms of motors driven by chemical energy. First we study the simple depot model and give analytical solutions including efficiency and stochastic effects. Then we introduce internal oscillations based on inertia including variable friction functions. Further we replace inertia by delay effects and study motors in trigger regime. As possible applications we consider a model of ATP-driven motors operating on angle and elasticity variables. We develop a model of F1-ATPase motors with three β-subunits which drive the rotation of the central γ-shaft. |
