A prototype of a three-phase brushless DC electric motor for medium-class multi-rotor drones has been developed at Tomsk State University (TSU). This was reported in the press service of the university.
The new engine is designed to operate in harsh weather conditions. The development will make unmanned aerial systems more reliable and reduce maintenance intervals.
According to the technical director of the development team, Ivan Sukhovolsky, the laboratory of the project park of the Faculty of Physics and Technology needs affordable and high-quality motors, which now have to be purchased. The main goal was to create reliable UAV engines with a maximum thrust of up to 5 kg, consisting entirely of domestic components.
In the project park, we assembled our first prototype, the body is made by 3D printing on a photopolymer printer. Then we made a fully metal electric motor, which can already be used in a drone, and we are now in the testing phase.
The motor has a protected closed-type housing. This allows it to be used in various production and climatic conditions. The development will reduce the time and costs of servicing drones.
The speed of the electric motor reaches 11,000 revolutions per minute, the voltage is up to 25 V, and the winding temperature during standard operation does not exceed 50°C.
Earlier www1.ru reported that the production of engines for drones will be established in Krasnoyarsk.
