A piston generator is provided to remove electricity supply connection by using a permanent magnet instead of an electromagnet and need not to supply separate electric energy since the electromagnet is not used. A piston generator includes an external electric motor or motor and other devices, a permanent magnet cylinder, coil bundles(1,5), a piston(8), a lubricating system(18). The permanent magnet cylinder is manufactured by inserting several donut type permanent magnets(3) into a permanent magnet fixing cylinder(4) when power is transmitted to a power connecting device. The coil bundles are wound on an internal spool type cylinder(6) and an external spool type cylinder(2). The coil bundles are inserted into the piston. A piston guide cylinder(7) is inserted into the internal spool type cylinder. The lubricating system reduces friction force between the piston guide cylinder and the piston, and reduces the abrasion of the piston guide cylinder and the piston. |
