| 摘要 |
A device for generating electrical or mechanical output, comprising a stator coil, a stator assembly, a rotor coil, a rotor assembly rotational about an axis, the rotor assembly at least partially surrounding the rotor coil, rotator extensions capable of induced magnetization and extending from the rotator, each rotator extension having a rotor extension surface, wherein magnetic flux leakage between the rotator extension surfaces is prevented or reduced via permanent magnet elements located at the rotator extension surfaces. Stator and rotor may be reversed in operation.
