PURPOSE: To enable an installation of a transportation instrument at any place along a transport pipe for a fluid by arranging a rotor fitted with blades inside a transport pipe and by rotating the rotor by magnetizing driving coils arranged around an outside periphery of the pipe so as to transport the fluid in the pipe with the blades.
CONSTITUTION: For the purpose of transporting a fluid, a rotor 22 fitted with blades 25 is arranged free to rotate inside a pipe 21, and driving coils 23 are also arranged around an outside periphery of the pipe in order to rotate the rotor 22 inside the pipe 21. Further, a magnetic substance 26 is set in the rotor 22 which responses to a magnetic field when the driving coils 23 are magnetized. This apparatus can be installed at any place along the pipe as a result. A sealing for a driving shaft penetrating a pipe, a driving shaft disturbing a fluid flow and an outer casing of a rotor become needless, by using this apparatus.
