Abstract
The underlying invention relates in particular to a forming machine, having an electromagnetic linear motor with a linear mover and multiple coil units each with a predetermined coil pole pitch (S) which is measured in the direction of the movement axis. The linear mover includes, in an alternating arrangement along the longitudinal axis (L) thereof, first permanent magnets which are magnetized transversely to the longitudinal axis with a predetermined first magnetic pitch (T1) and second permanent magnets which are magnetized in the direction of the longitudinal axis (L) with a predetermined second magnetic pitch (T2), wherein a ratio of coil width (S) to first magnetic pitch (T1) is 3:1, and wherein a ratio of first magnetic pitch (T1) to second magnetic pitch (T2) is 2:1.
