Launching apparatus using rotating magnetic body
The present invention relates to a launching apparatus and, more particularly, to a launching apparatus using a revolving magnetic body, wherein the apparatus is safe and is capable of being driven with low power consumption, the apparatus including: an acceleration pipe formed by spirally winding a hollow pipe made of a non-magnetic material; a stator wound with a plurality of coils to encompass an outside of the acceleration pipe, and forming a magnetic field by being magnetized when an electric current is applied thereto; and a magnetic body launched outside after revolving along a circumference of the acceleration pipe due to a force exerted thereto by the magnetic field.
1. A launching apparatus using a revolving magnetic body, the apparatus comprising:
an acceleration pipe ( 100 ) formed by winding a hollow pipe made of a non-magnetic material;
a stator ( 200 ) wound with a plurality of coils to encompass an outside of the acceleration pipe ( 100 ), and forming a magnetic field by being magnetized when an electric current is applied thereto; and
a magnetic body ( 10 ) launched outside after revolving around a circumference of the acceleration pipe ( 100 ) due to a force exerted thereto by the magnetic field,
wherein a rotor ( 300 ) is provided inside the acceleration pipe ( 100 ) and is rotated about a shaft ( 400 ) provided therein, so that a rotational force of the rotor ( 300 ) is usable.
2. The apparatus of claim 1 , wherein the coils wound on the stator ( 200 ) form one pole, wherein
the pole is formed of 2n in number, where n is an integer, such that speed of revolution of the magnetic body ( 10 ) is adjusted depending on the number of the poles.
3. The apparatus of claim 1 , further comprising
a regulator regulating frequency of the electric current applied to the stator ( 200 ), such that speed of revolution of the magnetic body ( 10 ) is adjusted.
4. The apparatus of claim 1 , wherein the acceleration pipe ( 100 ) is provided at an end thereof with an outlet pipe ( 110 ) through which the magnetic body ( 10 ) is launched outside, the outlet pipe ( 110 ) being provided with a helical groove formed on an inner surface thereof.
5. The apparatus of claim 4 , wherein a certain portion of the outlet pipe ( 110 ) is made of a flexible material such that the outlet pipe is directed to a direction in which the magnetic body ( 10 ) is launched.
6. The apparatus of claim 1 , wherein the rotor ( 300 ) includes any one of a plurality of permanent magnets and iron.
7. The apparatus of claim 5 , wherein a viscous fluid composed of heating medium oil is readily used for lubrication and heat transfer.
