Beware the danger of dust to electric motors

While an electric motor is doing its job and operating normally, it’s easy to ignore potential hazards such as moisture, heat and dust. Why dust, you ask? If dust particles suspended in the air are fine enough, they may find their way into an electric motor and once inside can cause damage in a number of ways:

  • If allowed to build up, dust can block cooling passages, which may lead to overheating and failure.
  • Abrasive dust – such as mineral ore particles – will, over time, wear down components. Therefore motors used in the mining and crushing processes are particularly exposed to abrasive dust.
  • Some particles can carry static charge and are therefore electrically conductive, so may interfere with currents

To help prevent dust contamination, users should choose a motor with the relevant Ingress Protection (IP) rating. The IP system classifies the degree of protection against intrusion from objects, dust and moisture by mechanical and electrical equipment casings. This rating ranges from no special protection (0) to hermetically-sealed enclosures that guard fully against dust (6).

If it’s too late for your electric motor and you’d like it repaired, we provide a free collection and delivery service within a 50-mile radius of our workshop and offer an emergency next-day service wherever possible. There’s a 12-month warranty on repairs and we can attend site if required, so call Matthew Gibbons on 07970676272 or email for a motor rewinding quote.
