  • METHOD AND SYSTEM FOR MONITORING OPERATION STATUS OF AN ELECTRIC MOTOR IN REAL TIME
    Publication number: 20230204640
    Abstract: A method for monitoring operation status of an electric motor in real time, including: reading a drive application signal of the electric motor; selecting a frequency to be observed; analyzing the frequency to be observed to obtain a spectrum thereof; analyzing the spectrum; and detecting the operation status of the electric motor on the basis of the spectrum analysis.

  • Electric motor control
    Patent number: 11646687
    Abstract: Examples include a method for controlling an electric motor using a variable speed drive based on input parameters of the variable speed drive. The method uses initial estimated parameters of an electric motor and measurements of the variable speed drive at operating points of the electric motor to determine accurate input parameters of the variable speed drive.

  • Method and system of internal temperatures determination in a synchronous electrical machine using state observers
    Patent number: 9383265
    Abstract: The invention relates to a method of determining internal temperatures (2) (coil and magnet temperatures) in a synchronous electrical machine (4) using state observers for the resistance of the coils and the magnetic flux of the magnet. The invention also relates to a diagnostic method, a control method and system (3) for controlling a synchronous electrical machine from the internal temperatures thus determined.

  • Method of controlling a device for converting wave energy to electrical energy
    Patent number: 9261070
    Abstract: The invention converts wave energy into electrical energy. A device moved by wave action is coupled to an electric machine for generating electrical power and to drive the device to improve conversion of wave action into electrical power. The conversion of the wave energy is improved through real-time estimation of forces exerted by waves on a pendulum axis to estimate the force to be applied to the device by the electric machine acting as an electrical motor.
