2024: Product Announcement

In early August 2024, the Russian engineering company Sovelmash presented the world's first heavy unmanned aerial vehicle (UAV) equipped with asynchronous engines. A drone called the Moth can be used to transport various cargoes.

"Moth" is made according to the quadcopter scheme. Each of the four propeller motors is based on an asynchronous motor-wheel of size 318. The maximum power of such an engine is 60 kW. The drone is almost completely made of domestic components - with the exception of control controllers and batteries. In the future, exclusively Russian components will be used.

The asynchronous motor-wheel of the 318th dimension is made on the basis of the patented technology of combined windings "Slavyanka." Its peculiarity lies in the fact that two types of windings are combined in one electric motor - "star" and "triangle." These windings are laid in slots so that the resulting magnetic flux induction vectors of pairs of poles of the same phase "star" and "triangle" form an angle of 30 electric degrees between each other.

The combination of two circuits in one winding allows to improve the shape of the field in the working gap of the motor and, therefore, optimize the basic characteristics. Among the advantages of such motors are named: increasing the starting moment, increasing the class of energy efficiency, reducing the cost, increasing reliability, reducing the level of noise and vibration, reducing starting currents. It is alleged that thanks to the use of Slavyanka technology, the Motylek drone has no analogues as of early August 2024. The new engines are said to have unique characteristics and surpass all the global developments that exist on the market.^[1]
