Servomotors are widely used and well known by hobbyists for control of small scale radio controlled boats, cars or planes. The control is done using a simple PWM signal modulation, easily compatible with a 2 or 4 channels remote control system. As hobbyists are generally simple users, a light knowledge is generally enough to drive this kind of motor. However, in some electronic applications, we need deeper information on servomotors behaviour. Unfortunately, servo manufacturers never give detailed datasheet and no information is available on various WEB sites. Thus, we present in this paper, a SPICE modelling for hobbyist servomotor. Simulation and practical experimentations are done to validate the modelling. Finally, an additional lively 3D modelling is proposed and a concrete didactical application is described before conclusion
