Abstract
An inner magnet rotor for a magnet pump includes a yoke, magnets arranged on the yoke, a first holder, affixed to the yoke, for tightly holding the magnets at the front side of the yoke, and a second holder, affixed to the yoke for tightly holding the magnets at the rear side of the yoke. The first and second holders are lower in hardness than the magnets, and the magnets are chamfered at each of their front and rear ends to form a bevel face. Each of the first and second holders are formed with a slanting face opposed to the bevel face, the slanting face of each of the holders being at a smaller angle with respect to the axis of the rotor than the bevel face of each of the magnets before each holder is affixed to the yoke.
