摘要

Linear motor has a stator and a rotor with the stator having a stator joke and the rotor a rotor yoke. The rotor yoke (8) has pockets (17) that extend longitudinally between the axial ends of the rotor and radially from the inside to the outside of the yoke. The pockets are filled with a magnetically conducting, and in the circumferential direction, electrically insulating filling material, e.g. oxidized or varnished metal plate.
