Sažetak
Brief overview of the state of the art in the area of production and application of the electrical drives with permanent magnet (PM) motors ( with the emphasis on the servodrives ) is displayed. Besides, regarding the fact that electrical drives with PM motors are widely applied in the systems with autonomous power supply, operating features of these electrical drives are described. Comparison of some characteristics of the electronically commutated motor ( ECM) and synchronous molor with permanenI magnets (SMPM ), from the point of view of applicability in the servodrives, as well as the short comparison of the different types of the electrical servodrives, are layed out. Parameters which are especially important for the selection of the servomotor in a system with autonomous power supply were stressed out. Furthermore, the compensation method for elimination 01 the torque ripples, based on the appropriate choice 01 the con/ral structure, is pointed out. Using this compensation method the torque ripples are reduced under 2% in both cases ( situation with the torque ripp/es still being slightly in favor of SMPM ). The derived conclusions concerning torque ripples are valid for the drives with line power supply as well as for the drives with autonomous power supplies.
