No replacement available? We can rebuild it
If your EM3311T is obsolete, has a long lead time, or is a custom build, our shop — Current Electric Motor Supply — repairs and rewinds motors up to 800 HP. Send the nameplate and we'll tell you honestly whether a rewind makes sense or a new replacement is the better move.
Confirming the right replacement
Before we quote, compare these fields on your failed motor's nameplate. If any of them differ, send us a photo of the nameplate and we'll match it exactly rather than guessing:
- Full model number — including any suffix letters
- HP, RPM, and voltage
- Frame size (e.g. 284T) and enclosure (TEFC, ODP, etc.)
- Full-load amps
