Abstract:
1. A system for control of rotational speed and power, the system comprising: at least one motor or generator; a control system, connected to and arranged to control a first control board, the first control board being connected to and arranged to control the at least one motor or generator; wherein a rotating process machine rotates with a rotational speed given by the at least one motor or generator; wherein the at least one motor or generator is connected to the control system and the rotational speed of the at least one motor or generator is controlled by the control system; and wherein the rotating process machine comprises: an adjustable load control, wherein the control system is connected to the rotating process machine and controls the adjustable load control in the rotating process machine to achieve soft transitions between several selectable rotational speeds and lower energy consumption by step by step adjusting a size and rotational speed of the at least one motor or generator to varying energy requirements.
