The adiabatic quantum motors [1] are nanometricscale's machines which can provide a mechanic workfrom a flux of quantum particles. So, it's necessary adeep knowledge of the current induce forces and yoursnon-conservative contributions. In this work, we study aone dimensional system which consists in a quantumdot connected with to reservoirs, under a noninteraction particles tight binding model [2]. Over thissystem, we analyzed the equilibrium forces, nonequilibrium forces and energy dissipation through greenfunctions and scattering matrix [3]. Our main goal is therole of resonants states on the system, the dynamicalphase transitions of localized -non localized states[4,5]and the correlations with current induced forces overthe system. With this aim in mind, we want tounderstand how we can perform a nanomotor oranother kind of nano-electro-mechanical devices.
