A method of making a magnet arrangement including a cylindrical magnet, pole shoes surrounding and resting against the magnets, the pole shoes formed of hollow cylinder sections, and two cover plates placed on the end faces of the magnet and the pole shoes, wherein the cover plates are connected to the pole shoes. The inner surfaces of the pole shoes facing the magnet have, before being placed on the magnet, a radius different from the radius of the outer cylindrical surface on the magnet. The magnet arrangement is obtained by placing the pole shoes against the magnet, pressing the pole shoes against the magnet until the radius of the outer surface of the magnet and the radius of the inner surfaces of the pole shoes are equal, and welding the cover plates and the pole shoes together. In the resulting magnet arrangement, the finish of the magnet must not need narrow tolerances, and it is ensured that no air gaps exist between the inner surfaces of the pole shoes and the outer surface of the magnet. |
