CONTROLLED MOTION SYSTEM HAVING END TEETH TO FACILITATE THE FORMATION OF A MAGNETIC FLUX BRIDGE JOINING LINEAR MOTOR SECTIONS

摘要

A linear controlled motion system include a track formed from one or more track sections and having at least one mover mounted to the track and effective for receiving articles at one location and transporting the articles to another location. The system includes at least one magnetic linear motion motor for providing a magnetic field effective for moving each mover in a controlled motion along the track and a magnetic flux bridge for reducing changes in the magnetic flux that reduces the efficiency or interferes with the operation of the controlled motion system. The ends of each track section of the magnetic linear motion motor may include end teeth that have a small recess in the top portion thereof. The recesses may be sized to fit the lip of a cover placed over the track section so that the ends of each track section form substantially smooth and planar surfaces that may be joined together to substantially eliminate any air gap between the joined track sections.

主权项

1. A controlled motion system comprising:
a track formed from two or more track sections positioned adjacent to one another, each track section having a housing, a cover and a linear magnetic motor disposed in the housing, wherein the linear magnetic motor includes an end tooth on each end and a plurality of intervening teeth, wherein at least some of the plurality of intervening teeth include electromagnetic coils configured to produce a magnetic flux; one or more movers mounted to move along the track by utilizing the magnetic flux; and a respective magnetic flux bridge connecting each of the adjacent track sections together, each respective magnetic flux bridge being formed from the end teeth of the adjacent track sections, wherein each of the end teeth of the adjacent track sections form a substantially smooth surface configured to abut against one another to form a magnetic flux path, and wherein each of the end teeth include a recess sized to fit a lip of the cover.
