Abstract:
1. A primary component for a linear motor, comprising: a magnetically conducting laminated core having teeth projecting towards a secondary component of the linear motor and encompassed by coils, and a magnetically conducting tooth without a coil arranged on an end region of the laminated core and having a free section projecting towards the secondary component of the linear motor and forming a flux guiding element for reducing force ripple, said free section formed in two pieces and comprising at least one plastic section having low electrical conductivity and a negligibly small magnetic conductivity and providing a defined gap with a defined gap spacing between the two pieces, said at least one plastic section arranged between the two pieces in a plane extending substantially perpendicular a projection direction of the free section, said teeth and the tooth without a coil being spaced apart from the secondary component by a first air gap.
