About the inventions

Creation of different electrical machines with secondary windings placed in the stator (a rotor without a winding). This insures a high level of security, allows excluding the reductor from the machine formation, to simplify and increase the exactness of construction functioning.


  • Electric step-motors, torque and stabilized motors – in aeroplanes and spacecrafts (Russia)
  • Wind generators – in wind energetics («Baltnorvent» Ltd., Latvia)
