Abstract
Systems and methods are disclosed for active and passive electromagnetic switching for sortation shuttles along a track. An example system for active and passive electromagnetic switching for sortation shuttles may include a track having a first linear path and a first curved path that intersects the first linear path. The system may include a shuttle with a first ferrous block, the shuttle configured to move along the track, a first set of electromagnets disposed along a side of the first curved path, and a first set of permanent magnets disposed along a side of the first linear path. Energizing the first set of electromagnets causes the shuttle to merge onto the first curved path via interaction with the first ferrous block.
