The "Slavyanka" combined winding technology is based on the scientific and technological base created by Dmitriy Duyunov and his team.
 
The company "ASiPP", within the framework of which the technology was developed, and the company "Sovelmash" have received more than 20 patents for it.

The authenticity of the patents can be checked on the website of the Federal Institute of Industrial Property https://fips.ru/en/  You need to go to the "Open Registers" section - "Register of Inventions" and enter the number of the patent you are looking for in the "Value" field.

A large scope of motor research has also been conducted by independent experts. For example, at the University of Bologna, University Düsseldorf and Belgorod University. The test results are published on our website here https://solargroup.pro/en/technology

Combined winding electric motors are tested in the course of their development in the testing laboratory of "Sovelmash" using certified equipment. The test reports are available on the company's website here http://sovelmash.ru/en/documents.html

The research and practice of using the existing electric motors prove the efficiency of the "Slavyanka" technology and the results announced by Dmitriy Duyunov's team.
