Flood Damaged Motors at Dytecna

By on January 26, 2011

With recent flood damage to quarries and mine sites Electric Motors may have sustained flood damage. JOHN TREIMANIS from Dytecna (Asia Pacific) Pty Ltd reports.

IT is important that Members have an understanding of what they need to look for when assessing the impact of flood water and/or heavy rain on their electrical motors. The following article gives good practical advice.

Whilst motors may appear to be in working order they are difficult to assess safely. Circuit Breakers also suffer water damage which can lead to ‘live’ equipment. Prior to starting a motor consider damage sustained.

Electric motors cannot be left to dry out- they must be disassembled, serviced accordingly (which may only be bearings) dried and reassembled.

Replacement motors are a good option to get up and running quickly. However unique motors will require rewinding. As some motors can take days to rewind, a delivery date could be longer than usual with the amount of motors currently awaiting repair.
