The present invention relates to a method for mounting magnet elements on the surface of a rotor for use in a permanent magnet motor. The method comprises the steps of : providing a first tube like element, wherein said first tube like element has an inner diameter that corresponds to an outer diameter of said rotor, providing a second tube like element, wherein said second tube like element has an inner diameter that is larger than an outer diameter of said first tube like element, inserting said first tube like element into' said second tube like element, in order to create a hollow space between them, inserting a number of magnet elements into said hollow space, and inserting said rotor into said first tube like element, whereupon said magnet elements are in a tight fit arrangement between said first tube like element and said second tube like element.
L'invention concerne un procédé permettant de monter des éléments magnétiques sur la surface d'un rotor destiné à être utilisé dans un moteur à aimants permanents. Le procédé consiste : à utiliser un premier élément du type tube présentant un diamètre intérieur correspondant au diamètre extérieur de ce rotor, à utiliser un second élément du type tube présentant un diamètre intérieur supérieur au diamètre extérieur du premier élément du type tube, à insérer le premier élément du type tube dans le second élément du type tube afin de créer un espace creux entre les deux éléments, à insérer un certain nombre d'éléments magnétiques dans ledit espace creux et à insérer ce rotor dans le premier élément du type tube. Lesdits éléments magnétiques forment un ajustement serré entre le premier élément du type tube et le second élément du type tube.
