                         study and design of a reaction wheel experimental model are 
                         presented. A reaction wheel is used in the fine control of 
                         artificial satellite attitude by exchanging angular momentum 
                         between the wheel and the satellite. Reaction wheels consist, 
                         basically, of an electric motor that drives the wheel and is 
                         commanded by an electronic module that controls its torque or its 
                         speed. This electronic module is connected to the satellite 
                         attitude and orbit control logic module. The work is divided into 
                         the following steps: analysis of the several momentum actuators 
                         focusing in particular ball and magnetic bearing reaction wheels; 
                         settlement of specifications and mechanical design; analysis, 
                         design, and digital simulation of the speed control system; 
                         characterization tests and their comparison with results for 
                         reaction wheels available in the market; and performance tests and 
                         their comparison with the results from digital simulation.",
