7 SIT Diagnostic tool for motor-fan assembly
This tool allows the acquisition and analysis of vibration signals in motor-fan group in order to detect unbalancing in the fan.
The check of vibration on the motor-fan group is often not automatically performed in 100% of the production. Usually, a person is checking the level of noise and vibration with a high degree of subjectivity when the component is completely assembled. If the mechanical assembly of the motor and the fan is not properly performed, it may cause a higher level of noise and vibrations.
Automatic classification of the quality of the motor-fan sub-group is based on the acquisition of the vibration signals using a 3 axial accelerometer and then automatically classified using a neural network. The system is able to detect also if the accelerometer has been correctly mounted by the operator.
