Influence of frequency on the performance of integrated electric drive systems

Based on the algorithm design of brushless synchronous motors (brushless DC), this paper presents the influence of input quantities frequency of the electrical gateway (voltage, current) - for constant values obtained from the gateway machine (speed, torque) - on the geometric dimensions, parameters and functional stability of this category of electric drives. The analysis used the Matlab programming environment to design and visualise modes of frequency quantity variation (geometric size, operation parameters, other characteristic values). The stated purpose of the paper is to show that, in modern adjustable drive systems, it is necessary to create harmony between sub-components, and between the frequency of control sizes (supplied by static converter) and the natural frequency of mechanical structures (in particular, the electromechanical converter).
