<p>Permanent field rotor and a method of producing the same, wherein a fan-shaped silicon steel laminate (2) and a columnar permanent magnet (3) are alternately arranged circularly to form a cylinder, the magnetic poles of the columnar magnets (3) are brought into contact with the fan-shaped silicon steel laminate (2) to set the polarities in alternation, end plates (7) are brought into contact with both end surfaces (22) of the thus fabricated permanent magnet-yoke structure (11), corresponding through-holes (71, 21) are provided in the end plates (7) and in the fan-shaped silicon steel laminates (2), the permanent magnet-yoke structure (11) and the end plates (7) are fastened together with rods (5) that penetrate through the holes (71, 21), the end plates (7) undergo the deformation upon application of a mechanical force, the diameter of the through-hole (71) of the end plate (7) is smaller than the outer diameter of the rod (5), a plurality of slits are formed in the inner periphery of the through-hole (71) of the end plates (7), and the permanent magnet-yoke structure (11) and the end plates (7) are fastened together by caulking the end plates (7) to the rods (5).</p> |
