PURPOSE:To elevate the efficiency of a magnetic power machine by a method wherein ferrite pieces are sticked to the inside of cores made with electromagnets, and are magnetized is company with the cores to cut the absorbing power of the cores when the electromagnets are excited. CONSTITUTION:Ferrite pieces 7 are sticked to the inside of electromagnets 2, and a switching device is connected to the magnets 2 which becomes on state when the center B of a permanent magnet 5 passes the center point C of the electromagnets 2, and becomes off state when the magnet 5 passes by the magnets 2. The shape of the pieces 7 are selected properly to form magnetic field whose magnetic force against the magnet in the rotating direction A of the rotor 3 becomes small by co- operation of the adjoining permanent magnets 6, 6 and the magnet 2 when the magnet 2 is made to on state. By this way, the efficiency of the magnetic power source can be elevated utilizing efficiently the magnetic field of electromagnets. |
