Research of the Solar Electromagnetic Motor
The article presents the Mendocino solar engine and the solar unipolar engine and their shortcomings. A new solar electromagnetic engine was introduced. (Research purpose) The research purpose is in studying the electrical and mechanical characteristics of a solar electromagnetic motor. (Materials and methods) The LED digital switching DC power supply LW-K3010D; magnetic field detector; digital tachometers RPM, TL-900, DT-2234C; digital LED thermometer 1M-50⁓100; digital voltmeter 0.28 Inch Red; multimeters MAS830L, MAS838L, DT-181, HP-4070L; ammeters M4204; energy meter Dudget KIT MT-4014 were used during the study. The experimental method was used. (Results and discussion) Authors experimentally developed several engine designs. With a rotor diameter of 100 millimeters and a voltage of a high-voltage solar photovoltaic module of 110 volts, the power consumption is 0.44 watts, the rotor rotation speed is 750 rpm. The solar electromagnetic motor with a rotor diameter of 250 millimeters and a total rotor weight of one kilogram consumes 1.9 watts and has 100 rpm at free mode. (Conclusions) The article presents the designs of a solar electromagnetic motor in which there are no losses for eddy currents when the rotor rotates in a constant magnetic field of the stator, and the magnetic field of the rotor currents strengthens the magnetic field of the stator. The advantages of the proposed solar electromagnetic motor are high voltage and low currents in the electric windings, low energy consumption and no losses for eddy currents, for shading solar cells and for friction in sliding contacts. The results allow us to conclude the possibility of further development of solar electric machines using neodymium magnets, ionistors, high- voltage solar modules.
