<p>The direct drive has a stator with one or multiple support rings (3) that are made of plastic. The support rings supports the permanent magnets (2) that are arranged in two or more concentric rings (7). The annular or sector shaped stator logs (1), made of plastic, are arranged in axial direction adjacent to the concentric rings of the support rings in such a way that a magnetic flux is allowed in radial direction between adjacent concentric rings.</p> |
