Abstract

Disclosed are an apparatus for alarming an inverter status and an apparatus for analyzing a motor status in a mobile terminal. The apparatus for analyzing a motor status in a mobile terminal includes: a first recognition unit configured to recognize vibrations of a motor contacting thereto, and providing the vibrations to a controller; a second recognition unit configured to recognize sound of the motor, and providing the sound to the controller; and the controller configured to analyze a frequency from the vibrations and sound of the motor, to check a change of the vibrations, and thus to obtain an analysis result on a status of the motor.

Claims

1. A mobile terminal, comprising:

a first recognition unit configured to recognize vibrations of an electrical motor contacting thereto, and providing the vibrations to a controller;

a second recognition unit configured to recognize sound of the electrical motor, and providing the sound to the controller; and

the controller configured to analyze a frequency from the vibrations and sound of the electrical motor, to check a change of the vibrations, and thus to obtain an analysis result on a status of the electrical motor,

wherein the mobile terminal is positioned on a surface of a body of the electrical motor such that the first recognition unit detects the vibrations transmitted through the surface; and

wherein the controller is further configured to determine whether the analysis result on the status of the electrical motor is normal or abnormal by analyzing both the vibrations of the electrical motor recognized by the first recognition unit and the sound of the electrical motor recognized by the second recognition unit, and

wherein the first recognition unit is located within a body of the mobile terminal, and the electrical motor and the mobile terminal are physically distinct devices.

2. The mobile terminal of claim 1, further comprising a display unit configured to display the analysis result on the status of the electrical motor, under control of the controller.

3. The mobile terminal of claim 1, further comprising a user input unit having a layered structure with the display unit, and configured to receive a user'"'"'s input.

4. The mobile terminal of claim 1, wherein the controller obtains the analysis result on the status of the electrical motor using Fast Fourier Transform (FFT).

5. The mobile terminal of claim 1, further comprising a storage unit configured to store therein the analysis result on the status of the electrical motor output from the controller.
