Rotary drive

摘要

The rotary drive has a main shaft (1) mounted in bearing blocks and carrying a rare earth permanent magnet (6) and at least one rotation mass (5) which can be tilted wrt. the main shaft and a first axis (4). The rotation mass's center of gravity lies near the main shaft's axis: at least one drive arrangement which exerts pulses on the permanent magnet (6) takes the form of further rare earth permanent magnets (7,8) which receive pulses from an external power source via switches (9,11) dependent on the rotation distance, so the rotation mass is periodically tilted about the first axis towards the main shaft.
