Registration of active resistance of stator winding synchronous reluctance motor has shown that in reality the electromagnetic torque of this engine contains contrary to popular belief not one but three components, One of the new components does not depend on the angle the engine load is negative, i.e. it is the brake, and the sec-ond component is a harmonic function of the dual angle load and positive. The amplitudes of these new compo-nents, as well as the amplitude of the known component, depend on the inductive resistance of the motor stator winding along the longitudinal axis and fade relatively quickly with its increase, i.e. with an increase in engine power. On the other hand, the accounting of the specified active resistance results in the appearance of electrical losses in the stator winding, which allows to introduce into consideration the electrical efficiency of the stator winding. It turns out that at a certain value of the angle of the engine load, the efficiency reaches the maximum at a quite acceptable value of its cargo handling capacity. All this, in the end, allows you to design a synchronous jet engine with optimal transverse geometry, providing a high level of use of its active materials relative to the electromagnetic torque, and also with a given overload capacity at the maximum electric efficiency of the stator winding.
