The interaction of a moving screw dislocation with conduction electrons was considered for conventional pure superconductors. At temperatures below the critical temperature, so-called slow dislocations (which interacted only with thermally excited quasi-particles) and fast dislocations (which also broke up Cooper pairs) were considered. Near to the critical temperature, 2 limiting cases were analyzed, depending upon the relationship between the Meissner penetration depth and the anomalous skin-layer depth for the dislocation-induced electromagnetic field. The dependence of power dissipation upon temperature and dislocation velocity was obtained. It was shown that, due to a low field intensity in the short-wave part of the spectrum, the superconducting state was not destroyed by a moving dislocation; for a wide range of temperatures. Non-equilibrium states of the electron system, which were created by the dislocation field, were analyzed using a kinetic equation for a multi-mode excitation source. The dislocation field was shown to reduce the order parameter when far below the critical temperature, and stimulate superconductivity under some other conditions. A damping reduction, due to the stimulation effect, was identified.
