Connections of the battery can be connected to the respective consumer directly or via interconnected components.
- the drive element can be a drive spindle or another suitable element.

- the consumers can thus be supplied, for example with a corresponding design of the rotors.
- the actuator or actuators can be operated or moved as a consumer even when the drum is stationary and / or data and / or signals from sensors and feedback signals from actuators can be transmitted when a corresponding transmitter and / or receiver unit is provided on the rotor .
- This can be advantageous for various reasons, for example according to a variant to carry out a temperature measurement in a cooled (chamber) drum for sensitive products if a maximum temperature of the drum must not be exceeded before it is loaded with the product to be processed will.
- Another example is a level measurement, which can also be useful when the drum is stationary.
- a battery that is assigned to the rotor and rotates with it is that it can be used directly or, if necessary, in connection with other electrical components to provide relatively high electrical power, for example to provide a or to operate several actuators such as one or more closing valve (s), in particular designed as solenoid valve (s), or control valves of the drum.

Because according to this particularly advantageous variant of the invention, it is possible to store data on the operation of the centrifuge and in particular the operating behavior of the centrifuge directly on or in the rotor, and then read it out as required and, for example, by radio in an area outside the rotor for example to transmit to a stationary control device. Alternatively, it is possible to store and / or evaluate this data directly in the rotor, if or for what purpose a suitable computer device is then available there

- the use of the battery as an energy supply in the rotor can result in a wide variety of advantages.
- This energy available in pulsed form is essentially determined by the dimensions of the battery and less by a charging current.
- data which belong permanently to the drum and which, for example, document the history of a drum can be stored on this data memory.
- This can be, for example, data from strain gauges that register a possible exceeding of the load limit of the drum material, or operating hours of the drum, which can be used to determine the maintenance intervals, or data from impermissibly high acceleration, e.g. by exceeding the permissible speed or exceeding the maximum permissible Be the density of the product to be processed.

These can deliver data to the internal or also external data memory, whereby this data can be used to significantly improve the procedural properties of the machine by means of evaluation by an expert system and corresponding optimization software. This data can, however, also be sent to the control device outside the rotor in order to have a direct influence on process parameters such as the flow rate of the inlet to the centrifuge, the drum speed or the discharge frequency.

It can also have further elements such as a solids collector 22 and possibly also further elements such as one or more lines, damping elements, a lubricant preparation, etc. Such elements are only shown schematically or not shown here, since they are known to the person skilled in the art and can therefore be designed advantageously without further information.
