To determine the quality of electrical motors as well as to detect and isolate any faults.

A dedicated diagnostic algorithm calculates the features of the motor on the basis of measurements of electrical quantities, vibrations, sound, sparking and axial backlash. If all the features are within the prescribed limits, the motor is considered to be of appropriate quality. Otherwise, it is marked as defective and the algorithm reveals the location of the fault.

Several original algorithms have been designed, i.e., assessment of the sparking intensity, non-invasive isolation of the mechanical faults on the basis of acoustic measurements and a procedure for an extremely precise determination of the axial backlash of the rotor.

The fracion of defective motors delivered to the market is expected to be reduced by an order of magnitude, reduced production costs, better image of the manufacturer, better working environment.
