RESUMO:

This thesis aims at the study and construction of a prototype of a small three-phase induction motor (28.6 mm outside diameter and 15 mm height), with the external squirrel cage-type rotor being used as a Bearingless. This study started using a conventional Brushless motor and was adapted to function as an external rotor induction motor. The bearingless induction motor uses the split winding configuration to achieve radial positioning and torque. Simulation studies were performed using the Finite Element Method (FEM), effectively showing that it is possible to control the radial position and torque to keep the rotor spinning. A first prototype was successfully built and tested for a power of 100W showing good potential for applications in this power range and size, such as those applied in artificial heart systems. The control system was implemented using the Digital Signal Processor - DSP TMS 3208F335.
