Drive for accelerating and manoeuvring spacecraft

摘要

The invention relates to a mechanical drive for spacecraft. A shaft (2) is arranged rotatably in the frame (1). The shaft (2) is driven by the electric motor (11). At least 2 moment (force) arms (10) are arranged on the shaft (2). The moment arms (10) consist of the centrifugal weight (9), the centrifugal-weight arm (8) with its stop (8a), the electromagnet (6), the guide for the centrifugal-weight arm (7), and of the stop (7a). The current for the electromagnets (6) is transmitted via the two collectors (3) to the carbon brushes (4) and from the latter to the electromagnets (6). The collectors (3) are arranged around the shaft (2) and fixed on the frame (1). Each of the round collectors (3) is manufactured (13) up to 180 degrees from conducting material and up to 180 degrees from insulating material, so that a current can reach the electromagnets (6) only on the desired side. The collectors (3) are contacted from inside by the carbon brushes (4). <IMAGE>
