A ring motor (1) as a direct drive, particularly for vertical mills or rod mills, has a stator (6) and a rotor (12) configured as a rotating milling body (10), wherein the stator (6) has at least two different excitation systems, and the milling body (10) has only a toothed structure, which electromagnetically interacts with the excitation systems of the stator (6) and thus brings about a rotation of the milling body (10). |
