The invention discloses an
inertia generator, which comprises a fixed magnetic ring, a suspension magnetic ring and a generator motor. The generator motor is provided with a
motor shaft, the generatormotor drives the
motor shaft to rotate circumferentially after being connected with a current, and the generator motor enters a power generation state after the current is
cut off; the suspension magnetic ring is embedded in an insulating disc to form a rotor, and the insulating disc is made of an insulating material; the insulating disc can slide axially and is arranged on the
motor shaft in a manner of being incapable of rotating relative to a circumference; and the fixed magnetic ring and the suspension magnetic ring have
magnetism, and the gravity of the rotor is counteracted through a magnetic force between the fixed magnetic ring and the suspension magnetic ring so that the rotor can suspend. The rotor is lifted through the magnetic force of the fixed magnetic ring and the suspension magnetic ring so that the weight of the rotor can be effectively increased, but the rotor is suspended and hardly has the
friction force, the generator motor can drive the weight which is more thanseveral times of a rated load, the rotor weight is increased, and later rotation
inertia is greatly increased too; and therefore, a
generating capacity can be effectively improved.
