<p>The motor subjected to the present invention has an external rotor. The stator yoke (5) and the rotor yoke (2) are formed by a packing of magnetic lamination segments that are cut in 180° or smaller angles in order to complete 360° and joined with molten non-magnetic or non-polymeric metal or with rivets in the holes (9, 10) at the middle of the teeth. The rotor yoke (2) of said motor carries a series of permanent magnets (3) on its inner surface. The magnets are placed with no spaced apart intervals on the rotor yoke and fixed by a rotor body (1, fig. 1) and a rotor hub with the motor shaft (7, fig. 2). Both the rotor body and the rotor hub are made of non-polymeric or non-magnetic metal suitable for injection casting, or made directly with the motor shaft (7).</p> |
