Annotation: The article is devoted to the features of the circuit solutions development for noise-resistant electronic speed controllers of brushless electric motors for unmanned aircraft. It analyzes the operating features, that allowed to formulate the technical re-quirements for a whole class of devices. When analyzing the state-of-the-art, it was concluded that the development of a solu-tion with full program control is highly relevant. The basic prin-ciples for controlling a brushless electric motor, recommended for constructing a regulator, are presented. As a practical solu-tion, a structural and circuit diagram has been developed de-scribing the operation of the main elements. In the conclusion, the practical results of testing this regulator are considered. The assessment at the current stage is provided, as well as the ways to improve and develop the regulator in the near future.
