The magnetic torques arise from permanent magnets mounted at the free end of the arm and along a circle. The electrical subsystem is powered by two forms of input signal (DC and AC voltage sources). For each case, we determine the condition for complete rotation of the mechanical arm versus the parameters of the system such as the arm length, the number of magnets, and the frequency of the external signal. The nonlinear dynamics of the system is examined by means of time-histories, bifurcation diagrams, Lyapunov exponents and phase portraits. Chaotic and periodic dynamics are detected numerically and confirmed experimentally. <\/jats:p>","DOI":"10.1142\/s0218127423500529","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T09:06:31Z","timestamp":1682672791000},"source":"Crossref","is-referenced-by-count":6,"title":["Dynamics of the Rotating Arm of an Electromechanical System Subjected to the Action of Circularly Placed Magnets: Numerical Study and Experiment"],"prefix":"10.1142","volume":"33","author":[{"given":"R.","family":"Kouam Tagne","sequence":"first","affiliation":[{"name":"Laboratory of Modelling and Simulation in Engineering, Biomimetics and Prototypes, Faculty of Science, University of Yaound\u00e9 I, P.
