Abstract :
A sensorless direct rotor field oriented control (SDRFO) scheme of three-phase induction motors for low cost applications is presented in this paper. The SDRFOC algorithm is based on a sensorless rotor flux closed-loop observer whose main advantages are its simplicity and robustness to motor parameter detuning. The whole algorithm has been developed and implemented on a low-cost fixed-point DSP controller. Experimental results are presented for a 0.5 kW induction motor used to drive a vacuum primary pump used in industry applications
