The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital signal processor (DSP) an algorithm of speed estimation using the current and voltage acquisition. Those methods become realizable on DSP of low costs. The goal of this work is to design, develop and implement of sensorless speed digital control of an electric motorization. The position and the mechanical speed of motor are calculated according to: observed rotor flux and the slip pulsation. The algorithm is implemented in DSPic30f of Microchip.
