The compact motor for energetic use of the Effect has two horizontal and displaced rotary masses lying one above the other at a tiny distance. They consist of vertical flat bars which are almost springy and horizontally resistant to bending and have compact masses at their ends. They are driven in opposite directions but synchronously in phase via short vertical axles from motors fastened eccentrically to a central shaft. The central shaft is located in a vertical frame rotating about a vertical axis. The frame has a vertical shaft inserted into the motor housing with driven ends. The central shaft is connected to its two ends with swivel motors which can swivel it and the two rotary masses by 180 degrees. The swiveling always takes place when central shaft, vertical frame and the arms of the two rotary masses lie in the east/west direction.
