IEC EX Certified Repair
IEC EX Certified Repair
(OP)
Hi,
I have an 800 KW, 4 Pole, 6600 volt IEC EX (CE 1180 Ex II 2G) motor on a coal conveyor. I need to send the motor in for repair/rebuild. The motor was built in Portugal. My normal repair shop doesn't feel that they are qualified to work on it, they are UL certified but are not an IECEx certified repair facility. Should I/they be concerned? Where can I find a shop here in the States that can work on this motor and not void the IECEx certification.
Thank You

Is this an underground or surface application? Mining equipment is usually marked Group I.

If the motor does bear US certification markings can the repair not be done by a certified shop over there?

Any option for replacing the motor with one from the surplus market? Machinery breakers and scrap men seem to have plenty of stock given the number of companies failing at present. Might be cheaper than shipping it to Europe for repair if you can trade in the motor you have.

I know this does not help anyone in the USA, but it is a complex area.
I was involved in the very early days of this, when then UK repair indudstry seemed to want a "carte blanche" permit to repair Ex motors, without thought to the potential breach of the design standards.
