This work describes the Vectorial Speed Control System of a triphasic bearingless induction machine with divided windings of 1.1 kW. The control strategy used in this system is the quadrature vectorial control. To implement the control algorithm, was chosen the rotor flux referential, which is being estimated through the stator winding currents and the rotor speed. The vectorial speed controller operates in synchronism with the radial positioning controller, but these controllers should work with low mutual influence. The control system is being implemented in a 16 bits DSP (Digital Signal Processor), which operates at 40 MHz. The algorithm was developed in the ANSI C language.
