For the weak fault characteristics in the external stray magnetic field when the motor bearing faults, this paper proposes a fault detection method based on Teager–Kaiser energy operator. Firstly, it is theoretically analyzed that the application of the Teager–Kaiser energy operator to the stray magnetic field can not only demodulate the fault characteristic frequency, but also enhance the amplitude of the weak fault characteristic frequency, thereby improving the fault detection capability. Experimental test with artificial bearing defect was conducted by measuring stray magnetic field; the experimental results verify that the proposed method can effectively extract weak fault features in stray magnetic field.
