This paper presents the study and implementation a vector control strategy using supply voltage. Firstly, the mathematical model of the system is set according to engineering practice, which determined the spatial position of the rotor flux. In the case of brushless AC, ie immediately, since the rotor flux is aligned with the direct axis of the rotor, and this type of machine no slipping. Thus, to determine the rotor position by measuring or estimating the position of the flow is also determined. The proposed control strategy is verified by simulation via Matlab / Simulink program. The simulation results show that the method using vector control has a better performance compared to the control scale.
