FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to DC motors with a permanent magnet using a solar photovoltaic generator to power the rotor winding. In a solar electromagnetic motor containing a rotor with an axis of rotation, a photovoltaic generator made of switched solar cells with p-n junctions connected to electric coils, a stator and a permanent magnet, the rotor is made in the form of a cylinder, on the side surface of which flat permanent magnets are installed in several rows with a gap between the rows. The permanent magnets in each row are fixed with a gap between the magnets in one plane passing through the axis of rotation of the rotor. The neighboring magnets in each row are oriented with opposite poles in relation to each other. Each boundary of the gap between the magnets in each row is located in a plane perpendicular to the axis of rotation of the rotor. The orientation of the magnets in all rows is the same. Opposite each row of rotor magnets, along each gap between the magnets in a plane perpendicular to the axis of rotation of the rotor, electric stator coils are installed on one side. In another variant, the opposite side of each stator coil is rotated 180° in the stator and installed in a plane perpendicular to the axis of rotation of the rotor along the adjacent gap between adjacent magnets in a row with opposite pole orientation. A photovoltaic generator made of switched solar cells is installed on the stator and connected via a diode, an energy storage device and a pulse switching device with electric coils. The pulse switching device contains a sensor for monitoring the location of the stator coil in the gap of the rotor magnets and a switch for supplying pulsed current and voltage to the stator electric coils from a photoelectric generator.

EFFECT: more complete use of the energy of solar cells and an increase in their voltage, as well as in reducing losses in the rotor by eliminating sliding contacts, increasing the number of permanent magnets, changing the configuration of the magnetic field and using pulsed power supply of electric windings.
