  • Magnets in electrical machines
    Patent number: 11837918
    Abstract: The present disclosure relates to rotors for an electrical machine comprising a first type of permanent magnets, and a second type of permanent magnets, wherein the first and the second types of permanent magnets have a same magnetic strength, and wherein the first type of permanent magnets has a first temperature rating, and the second type of permanent magnets has a second temperature rating different from the first temperature rating. The present disclosure relates to generators, and in particular to wind turbines comprising such generators and to methods for selecting or providing magnets for permanent magnet rotors.
    Type: Grant

  • Root-cause analysis system and associated methods
    Patent number: 8407170
    Abstract: A method for determining a root cause of a problem in a multiple-element system includes correlating an incoming alarm signal with an element x in a multiple-element system and accessing an implication list comprising a list of all elements upstream of element x. At least one element on the implication list is weighted with data relating to the at least one element. Taking into account the weighting step, a probability is calculated that an element on the implication list comprises a most-probable root cause of the subsequent alarm signal. The identified most-probable root cause of the incoming alarm signal is output.
