Abstract
A device that utilizes the force on a current carrying conductor placed in a magnetic field to produce thrust without the need either to push against an external medium, surface or object, or to eject mass is disclosed. The device utilizes freedom of movement between either the current carrying conductor and the rest of the device or the source of the magnetic field and the rest of the device to prevent action and reaction from cancelling each other out. In an embodiment of the invention, windings on stators (101) act as the current carrying conductor while electromagnets on rotors (105) produce the magnetic field. The overall result is that the whole device experiences a thrust and accelerates (moves) linearly while the movable parts rotate. Various embodiments are disclosed.
Claims
1. An electromechanical device that comprises two rotors each fitted with two or more electromagnets and two stators that have insulated conductor coils wound on them. The two stators are placed adjacent to each other between the said rotors and are rigidly fixed to the casing of the device. The rotors are free to rotate. The electromagnets are arranged on each rotor in such a manner that the rotor is balanced. The poles of each electromagnet face each other with a gap between them. The stators are sufficiently narrow to fit in the gap between the poles of the electromagnets on the rotors. When the electromagnets over the area where the two stators are nearest each other are energized, magnetic fields that are at right angles to the currents in the windings on the stators are setup between the poles of the said electromagnets. The stators experience forces that are at right angles to both the currents in their windings and the applied magnetic fields. The rotors experience reaction forces that are equal and opposite to the forces on the stators and rotate as a direct consequence of the said reaction forces bringing the next set of electromagnets over the area where the stators are nearest each other. The reaction forces are not transmitted to the rest of the device due to the freedom of movement of the rotors. The forces on the stators, however, are transmitted to the whole device including the rotors, causing the device to move linearly without either the need to push against any external medium, surface or object or the need to eject mass. The device thus pushes or pulls any load attached to it.
2. An electromechanical device as in claim 1, wherein the stator coils and the electromagnets on the rotors are electrically connected to each other in series.
