Brushless dc electric motors have found application in various branches of domestic technology, including in highly important aviation applications, the creation of the electrical complexes of which requires minimizing the weight and size indicators of all elements. However, due to the fact that such systems are often constructed on the basis of complex unique transmission mechanisms, their optimization is reduced to the constructive elaboration of the executive electric motor. For electromechanical converters with nonoverlapping concentrated multisection windings used in multipole machines, it is possible to achieve a significant reduction in the total mass by varying the height of the teeth and the length of the machine, taking into account the accepted volume restrictions. This kind of approach to the design of electric machines with a fractional number of slots per pole and phase allows one to create a magnetic system that provides a minimum of the mass of the product while maintaining the required electromechanical parameters by changing the tooth zone. The results obtained will make it possible, even at the stage of creating the sketch appearance of the magnetic system of the executive electric motor, to determine the optimal ratios of the parameters of the magnetic circuit, taking into account the possible minimum mass, which is relevant in the design of structurally complex electromechanical aviation systems.
