Abstract
In one embodiment, a propulsion system includes roaming vehicles including a reaction plate installed on a bottom of each of the roaming vehicles, a surface stator matrix installed with a running surface for the roaming vehicles and including single sided linear induction motors (SSLIMs). Each of the SSLIMs include two windings installed orthogonally to one another. The propulsion system also includes motor drives configured to electrically couple to the SSLIMs via a switching panel, and a control system configured to receive information related to the roaming vehicles, receive a desired motion profile for the roaming vehicles across the surface stator matrix, determine which of the SSLIMs to activate and a performance of the SSLIMs based on the desired motion profile, the information, or some combination thereof, and send control signals to the motor drives to control the SSLIMs to produce the motion profile.
