Linear motor coil assembly and linear motor

An ironless linear motor (5) comprising a magnet track (53) and a coil assembly (50) operating in cooperation with said magnet track (53) and having a plurality of concentrated multi-turn coils (31 a-f, 41 a-d, 51 a-k), wherein the end windings (31E) of the coils (31 a-f, 41 a-e) are substantially rounded, the coil part (31 S) between the end windings (31E) is straight and the coils (31 a-f, 41a-d, 51a-k) are arranged in an overlapping manner, wherein the end windings (31E) are pressed together, is provided. The coil assembly has the advantage to be flat, thus being easy to handle, and leading to a high steepness.
