Benefits of technology

The present invention relates to a system for controlling movement within a linear motion machine (LM) track. It includes a linear motor track made up of multiple coil elements and a magnetic component that moves the mover along it. An inductor is used to generate an electromagnetic force between the two components. This causes the mover to move itself around the LM track. There are sensors located at different locations throughout the track to monitor its parameters such as position, velocity, acceleration, etc., which can then transmit this information wirelessly to a receiving device.

Problems solved by technology

This patent describes a problem with current linear motors systems where only limited information can be obtained about the position and movement of each mover within its own frame. Existing solutions have limitations due to lack of knowledge of the movers' movements and payloads' positions themselves.

Embodiment Construction

[0027]While only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.

[0028]Turning now to the drawings, and referring first to FIG. 1A, a transport system 10 as illustrated for moving articles or products around a track 12. As will be appreciated by those skilled in the art, in many applications, the transport system will be configured to inter-operate with other machines, robots, conveyers, control equipment, and so forth (not separately shown) in an overall automation, packaging, material handling or other application. The transport system itself generally comprises a “linear motor” system as discussed below, in which the moving components are positioned, accelerated, decelerated, and generally moved under the influence of con
