ATEX Motor Repairs
If an ATEX motor fails, you're not just dealing with downtime — you're dealing with a compliance risk. Motors operating in potentially explosive atmospheres must be repaired to strict standards, by engineers who are certified to work on them. Mawdsleys BER is an AEMT Ex Registered Repairer, and every ATEX motor repair we carry out is completed in-house by Ex-certified engineers, to the standards required under IEC 60079-19.

Our ATEX motor repair process
- Inspection & compliance check — every motor is assessed against its original ATEX certification and zone rating before any work begins.
- Full mechanical and electrical diagnosis — winding resistance, insulation integrity and mechanical tolerances are all tested.
- Repair to Ex standard — any work required (rewind, bearing replacement, housing repair) is carried out to the exact tolerances and materials required to maintain ATEX compliance.
- Re-certification testing — the repaired motor is tested to confirm it meets the required protection standard before it leaves our workshop.
- Documentation — you receive a full repair report and compliance documentation for your records
Signs your ATEX motor needs repair
The earlier you catch these, the less it will cost — and the lower the compliance risk:
- Unusual noise or vibration
- Overheating
- Reduced performance or output
- Failure to start
- Any visible damage to the motor housing or protective covers
If your ATEX motor is showing any of these signs, don’t wait — in a hazardous area, a developing fault is a safety issue, not just a performance one.
Why ATEX compliance matters
Where an ATEX motor is present, you have a legal responsibility to ensure it meets and continues to meet the relevant standards — an incorrectly repaired motor can invalidate its certification even if it appears to run normally. That’s why every repair we carry out is completed by Ex-certified engineers, using the correct materials and tolerances for the motor’s protection type.
