From the middle ages to the renaissance, scientists and researchers have investigated the history of perpetual motion experiments and invented many of perpetual motion machines: Howard Robert Johnson, 1980 [23, 24], developed a permanent magnet motor and, on April 24, 1979, received U.S. Patent 4,151,431from the United States Patent office. Johnson pointed out that his device generates motion, either rotary or linear only from permanent magnets, acting against each other, in rotor as well as stator. He anticipated that permanent magnets made of proper hard materials should lose less than two percent of their magnetization in powering a device for 18 years.…show more content…
Flynn, 1995[25], His work relates to a method of producing useful energy with magnets as the driving force and represents an important improvement over known constructions and it is one which is simpler to construct can to be self-starting. Is easier to adjust, and is less expected to get out of adjustment, the present construction is also moderately easy to control, is relatively stable and produces an remarkable amount of produced energy considering the source of driving energy that is used. The present construction introduces permanent magnets as the source of driving energy but shows a novel means of controlling the magnetic interaction or coupling between the magnet members and in manner which is relatively rugged, produces a substantial amount of output energy and torque, and in a device capable of being used to generate significant amounts of…show more content…
This generator is powered by permanent magnets and so needs no fuel to run. Instead, it uses magnetic particles suspended in a liquid. The motor has a rotor which has four arms and which sits in a shallow of liquid which has a colloidal suspension of magnetic particles in it while outer fixed Cylinder has eight N pole Magnets. Inner rotating Cylinder has six poles Magnets. Magnetic Shielding is used to create N pole only. By altering the arrangement of the N pole magnet, minor rotation of the Inner cylinder will allow the magnetic repulsion to keep accelerating the inner cylinder–energy can then be extracted. Stephen Kundel, 2006, [28], A motor which has a rotor supported for rotation about an axis, with at least one pair of rotor magnets spaced angularity about the axis and supported on the rotor, one reciprocating magnet, and an actuator for moving the reciprocating magnet cyclically back and forth from the pair of rotor magnets, and consequently rotating the rotor magnets relative to the reciprocating
