Abstract
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.
