The document summarizes a student research project on developing an energy-efficient electric motor powered by photovoltaic cells. The students aimed to reduce the torque required to rotate the motor's rotor in order to use low-power energy sources like photovoltaic cells. They analyzed ways to reduce rotor resistance, tested the motor's dynamic and power characteristics, and estimated using alternative energy sources. Their research concluded that a magnetic bearing design could enable photovoltaic-powered operation and increase motor lifespan by removing brushes.

1. Have executed: Sharov Vlad, Tursunov Sergey, pupils 10 classes The energy-effective electric motor

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

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

12. Conclusions Application of a magnetic pillow in an engine design will allow to use sources of electric pressure of smaller power, including photo cells with the small area of a surface Decrease in starting value of force of a current in a rotor winding can be reached at the expense of application niodim magnets The offered model of the electric motor allows to exclude sliding contacts (brushes) from a design, that considerably will increase service life Model lack is strictly horizontal working position of the engine that it is possible to eliminate application of magnetic bearings

13. Estimation of average cost of the electric motor
