Abstract
In the field of electrical linear motors, it is known to make more than one laminate core (20) having teeth (22), wherein grooves (24) are designed between the teeth (22). Until now, coils assigned to the laminate core are arranged on each laminate core. The invention is based on this background. Instead, each coil (18) is arranged with a first section in a groove (24) of a first laminate core (20a) and with a second section in a groove (24) of a second laminate core (20b). The coils are consequently wound in an entirely different direction and now lie in a plane perpendicular to the direction of movement of the secondary part of the electrical linear motor.
