System and method for motor fault detection by space vector angular fluctuation

摘要

Systems and methodologies are disclosed for detecting faults and adverse conditions associated with electric motors. The method comprises obtaining a current signal associated with the motor, calculating a space vector from the current signal, determining a space vector angular fluctuation from the space vector, and analyzing the space vector angular fluctuation in order to detect at least one fault associated with the motor. Systems are disclosed having a diagnostics component adapted to obtain a space vector angular fluctuation from a current signal relating to operation of the motor, and to analyze the space vector angular fluctuation in order to detect at least one fault in the motor.
