Switching electromagnetic moving system
First Claim
1. A switching electromagnetic moving system comprising at least one track and at least one moving body located on said track, wherein:
- (i) said track comprises a power buss, at least two track sections and a controller;
(ii) each of said track sections has a contact surface and comprises electrically connected coil windings spaced apart in a series way along said track section to form a multi-phase linear stator;
(iii) said track sections are electrically connected in parallel with said power buss;
(iv) each coil winding is located on a plane that substantially coincides with said contact surface and has a magnetic axis substantially perpendicular to said contact surface;
(v) each track section has a switch and at least one sensor to detect the moving body position on said track;
(vi) said sensor of each track section controls the switch of the subsequent track section relative to the direction of the moving body displacement to apply power to the linear stator of said subsequent track section;
(vii) said sensor of each track section controls the switch of the preceding track section in respect to the direction of the moving body displacement to remove power from the linear stator of said preceding track section;
(viii) said moving body is placed upon said contact surface and comprises at least one magnetized object with magnetic axis substantially perpendicular to said contact surface such as to cause interaction with the linear stator when it is powered, thus creating a force tending to propel said moving body along said track.

Abstract
A switching electromagnetic moving system is comprised of at least one track and at least one moving body located on the track. The track is comprised of a power buss, at least two track sections and a controller. Each track section has a contact surface and comprises electrically connected coil windings spaced apart in a series way to form a multi-phase linear stator. Each track section has a switch and at least one sensor to detect the position of the moving body on the track. For each track section the sensor of the preceding track section relative to the direction of travel of the moving body controls the switch to power on and the sensor of the subsequent track section controls the switch to power off.
