摘要： The present invention relates to an automatic balance adjusting centrifuge which calculates the magnitude and the location of imbalance of itself based on the vibration generated in the dynamic state and automatically compensate for the imbalance based on the calculation, and the control method thereof. The method includes: (a) measuring the amount of vibration of a rotor of a centrifuge, supporting buckets that load samples, at a predetermined rotational velocity; (b) determining whether the amount of vibration measured in step (a) is greater than an allowed value; and (c) when the amplitude of the vibration is greater than the allowed value, compensating for a weight imbalance of the rotor by an amount calculated based on the vibration amount measured in step (a) and returning to step (a), otherwise, performing a centrifugal separation by accelerating the rotor to a working velocity.

摘要： It is described a method for balancing a rotor mounted on a hub of a wind turbine. The method includes measuring a parameter value of a parameter being indicative of the revolution frequency components of the rotor and/or of a generator of the wind turbine during operation of the wind turbine, calculating a change of the spatial mass distribution of the rotor based on the parameter value of the parameter, which change is needed for balancing the rotor, and balancing the spatial mass distribution of the rotor by using at least one balancing weight element being attachable to at least one blade of the rotor based on the calculated change of the spatial mass distribution. It is further described a system for balancing a rotor, a wind turbine, a computer program and a computer-readable medium, which are all adapted for carrying out the above described balancing method.
