1. Have executed: Sharov Vlad, Tursunov Sergey, pupils 10 classes Lycée№8 «Olimpia» The energy-effective electric motor The supervisor of studies: Marchuk Edward Viktorovich, The doctor fiz - mathematical sciences

2. The work purpose: working out and an experimental research of the energy-effective electric motor on photo cells Object of research: energy-effective electric drives Object of research: electric motor rotor on a magnetic pillow

3. Research hypothesis Reduction of the moment of force of the resistance operating on a rotor will allow to use low-power power supplies, including photo cells with the small area of a surface

4. Research problems 1) the analysis of ways of reduction of force of the resistance operating on a rotor of the electric motor at rotation 2) the analysis of dynamic and power characteristics of a rotor of the electric motor on a magnetic pillow 3) an estimation of possibility of application of alternative energy sources for creation of the rotary moment in the electric motor 4) project estimation of cost

5. Technical problems

6. Magnetic pillow and cargo ability of a rotor The maximum weight of loading 90 g + 0,196 g

8. Research of dynamics of a rotor

9. Force of a current in a rotor winding

10. Estimation of power parameters of a rotor I = 0.049 А

11. Dependence of force of a current in a winding from power of a source

13. Decrease in starting value of force of a current in a rotor winding can be reached at the expense of application niodimmagnets

14. The offered model of the electric motor allows to exclude sliding contacts (brushes) from a design, that considerably will increase service life
