This paper introduces a sensorless technique to drive independently dual Permanent Magnet Synchronous Motors (PMSM) based on Five-Leg Inverter (FLI). The main purpose of the proposed method is to eliminate the usage of speed sensor and to reduce the number of inverter switches from twelve to ten switches in the case of dual three-phase PMSMs drives. Despite the needs of speed sensor as the speed feedback for the dual PMSMs drives, there are no research done using sensorless technique in order to control independently dual three -phase PMSMs. A FLI contents ten switches which two switches represent as one leg. For the five legs available, one leg is commonly connected to both PMSMs. The drive is simulated by using MATLAB/Simulink. The simulation results of the performance for Dual PMSMs fed by a FLI at rated speed are successfully achieved and offer potential result for hardware implementation. The applied technique shows good speed regulation and proves that Dual PMSMs can independently control at different speed operation either in forward or re verse operating conditions as well as for load disturbance.
