Abstract
The present invention relates to a sorting system including a conveyor comprising a plurality of carts for carrying articles, in particular for sorting articles such as parcels and baggage. The conveyor has a linear synchronous motor drive system with stators arranged along a track which the carts follow. Accordingly, embodiments include an improved sorting system that provides an improved energy utilization and efficiency. Reaction elements are mounted on each of the carts. The reaction elements each comprise a number of permanent magnets arranged on a carrier plate. The magnets on reaction elements of adjacent carts are arranged to form a row of magnets with constant pitch and alternating polarity, said row having an interruption situated at a transition between adjacent carts. A maximum number of coils in the stator may thereby be active at the same time, when driving the conveyor.
