Application of model-based fault detection to a brushless DC motor

  title={Application of model-based fault detection to a brushless DC motor},
  author={Olaf Moseler and Rolf Isermann},
  journal={IEEE Trans. Industrial Electronics},
In comparison to classical dc motors, brushless dc motors are very reliable. Nevertheless, they can also fail, caused by, e.g., overheating or mechanical wear. This paper proposes a parameter estimation technique for fault detection on this type of motor. Simply by measuring the motor’s input and output signals, its parameters can be estimated. This method is based on a mathematical model of the process. In the presented work, a square-wave motor is considered. An appropriate model is derived… CONTINUE READING
