Abstract The problem of decrease in weight of an electric equipment of flying machines and increase of energy-efficiency this equipment is one of actual problems of exploitation and designing of such devices. Article is devoted one of variants of the decision of this problem, which is perspective for the small size pilotless flying machines. The operated electric motor of a special design, which are the basic block of a power-plant of a small size flying machine, is considered. The design of an anchor of the electric motor, which rotor is combined with the flying machine screw, is in detail enough described. Possibility of essential reduction of weight and volume of front parts of a winding of an anchor is shown. The control system includes elements of power electronic and is located on the core of an anchor of the electric motor – about winding conclusions. One of variants of the block diagram’s of a control system for frequency of rotation of the electric motor is considered. Laws of change of frequency and pressure of an anchor of the motor in modes of start and regulation of frequency of rotation of the screw are described. Results of an estimation of energyefficiency are resulted.
