The smoothness of variable speed drive operation is critical and a viable measure used in the design and development of motion control applications. The torque produced in a brushless DC (BLDC) motor with trapezoidal back electromotive force (BEMF) is constant under ideal conditions. However, in practice, torque ripple appears on the delivered output torque. Some of these ripples result from the natural structure of the motor, while some are related to the motor design parameters. Nevertheless, these torques could be minimized throughout the machine design process. Another source of ripples is associated with the control and drive side of the motor. This paper focuses on the torque ripples associated with machine control and drives that could be minimized by applying different control techniques. Various applied techniques for minimizing the torque ripples in BLDC are presented based on the motor control side. There are a variety of configurations to be adjusted based on the applied technique; in addition, hardware modifications or additional stages are also required. Other techniques, such as algorithm-based ones, could be applied to standard motor drive configurations.

Płynność zmian szybkości napędu jest istotną miarą używaną w projektowaniu i rozwoju zastosowań kontroli ruchu. Moment wytwarzany przez bezszczotkowy silnik DC z trapezoidalną zwrotną siłą elektromotoryczną jest stały w warunkach idealnych. Jednak w praktyce pojawiają się zafalowania momentu. Niektóre z tych zafalowań wynikają z naturalnej konstrukcji silnika, ale inną są związane z parametrami projektu i mogą być zmniejszane przez właściwe projektowanie. Inne zafalowania są związane z układem sterowania. Ten artykuł koncentruje się na zafalowaniach wynikających z techniki sterowania. Przedstawiono różne możliwości zmniejszania zafalowań.
