A moving coil type linear actuator system is provided to stably and linearly control a large load using relatively low electricity provided to a coil part. A moving coil type linear actuator system comprises a case(1), a central magnet(3), surrounding magnets(5), a coil part(7), a flapper unit(9), a plurality of springs(11), and a pneumatic pipe unit. The central magnet is installed in an inner center part of the case. The surrounding magnets are spaced a predetermined distance from each other and disposed to surround the central magnet. The coil part is inserted between the central magnet and the surrounding magnets to receive electric power to generate current flow perpendicular to a magnetic line formed from the central magnet and the surrounding magnets. The flapper unit is connected to the coil part. The plurality of springs supports the coil part and the flapper unit. The pneumatic pipe unit adjusts an amount of compressed air supplied from a compressed air source.
