With voltage measurement service in veins, DMC provides all interested in operating machinery bearings, whether manufacturers, whether end users, information on whether the bearings of the machines are at risk due to the passage of current.
electrical source bearing damage
- The capacitive coupling between the windings and the rotor can create stress on the motor shaft;
- this tension, You can discharge through the bearings, damaging them and reducing engine life;
- For motors controlled by variable frequency drives these voltages can be as high as 10 a 40 volts, peak.
- These higher levels, tensions can cause electrical discharges on the slopes of motor bearings, causing corrosion, melting craters and ridges, which can lead to premature bearing failure and motor.
