| 摘要 |
The disclosure relates to a motor- or generator-related arrangement or structure ( 20 ) with two parts ( 5, 15 ) rotatably disposed in relation to one another, where a first part ( 5 ), serving as rotor unit, is rotatably disposed about a shaft ( 7 ) in a first selected direction of rotation, and a second part ( 15 ), serving as stator unit, is rotatably disposed about said shaft ( 7 ) in a second selected direction of rotation counter directed to said first selected direction of rotation. Means ( 2, 3, 4, 14 and 13 ) are arranged for transforming the speed of the first direction of rotation to the second direction of rotation. Said means includes a first gear rim or ring ( 14 ), associated with the stator unit ( 15 ), at least two gear rotary wheels ( 4, 4 '), coordinated with a housing ( 1, 11 ), and a second gear rim or ring ( 3 ) associated with the rotor ( 5 ).
