In this manuscript, we study the relativistic quantum mechanics of anelectron in external fields in the spinning cosmic string spacetime. We obtainthe Dirac equation, write the first and second-order equations from it, andthen we solve these equations for bound states. We show that there are boundstates solutions for the first-order equation Dirac. For the second-orderequation, we show that its wave functions are given in terms of the Kummerfunctions and we determine the energies of the particle. We examine thebehavior of the energies as a function of the physical parameters of the model,such as rotation, curvature, magnetic field, Aharonov-Bohm flux, and quantumnumbers. Our study reveals that both curvature and rotation influence moreintensely when these parameters have values smaller than 0.3. We also findthat, depending on the values of these parameters, there are energynonpermissible levels.
