A secondary part provides a magnetic path for a primary part of a linear motor and includes a spacer element as well as yoke plates forming two limbs, which are arranged for an attachment to the spacer element so that—situated opposite each other—they extend in planes parallel to the magnetic path. In addition, the secondary part includes a plurality of permanent magnets, which are fixed in place on inner sides of the yoke plates pointing toward the magnetic path. The permanent magnets each have a width that decreases in an extension direction perpendicular to the magnetic path.

A laminated core (10) is provided for a stator or rotor of an electric machine. The laminated core (10) is formed from multiple laminations (12) that are stacked one on top of another in an axial direction (14) to form a lamination stack (16). A through-opening (18) is formed in the lamination stack (16) and extends parallel to the axial direction (14). A tie rod (20) of plastic is introduced, in particular injection molded, in the through-opening (18) to assemble the laminated core (10).

A motor unit includes a motor, a substrate, a motor case, a connector, and a restriction portion. In the motor, a rotor including a rotary shaft extending in an axial center direction rotates about an axial center of the rotary shaft as a rotation center. The substrate is provided with a circuit element constituting a drive circuit for driving the motor. The motor case houses the motor and holds the substrate. The connector includes a connection terminal directly connected to the substrate. The restriction portion restricts displacement of the connector with respect to the substrate by coming into contact with the connector.
