Abstract: The disclosure discloses a motor vibration or noise frequency detecting apparatus and method thereof. A processor and a frequency sensing unit are used to process and quantify a time domain signal, obtain a frequency domain result through computation, obtain a characteristic amplitude from the frequency domain result, and set characteristic amplitude as a trigger amplitude, which is then compared with a to-be-measured amplitude for use in computations or triggering events. The disclosure is used in a motor apparatus to detect a time domain abnormality, save power consumption for long-term use of frequency domain detection, and allow the motor to be monitored for a long time under battery power so the loss of the production line caused by the unwarranted shutdown can be avoided.
