SEW-Eurodrive questions
Why does my SEW-Eurodrive brakemotor keep burning up its brake?
Nine times out of ten it's brake air-gap adjustment: if the gap isn't even 360° around, the disc drags, overheats, and burns the coil — a complaint maintenance techs post about constantly. Check the gap with a feeler gauge against the spec plate first. If the brake has already cooked, the motor end usually needs rewind or replacement. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
My SEW gearmotor is leaking oil into the electrical box — is that repairable?
Yes — this is a known failure pattern plant techs report even on units under a year old: the input shaft seal weeps and oil migrates up into the terminal box. The fix is a proper input seal replacement plus cleaning and re-terminating the connections. Far cheaper than the 16-30 week factory replacement lead time.

SEW replacement lead time is months out — what are my options?
Practitioners describe exactly this trap: units either last forever or fail early, and then the factory quotes a 'ridiculously long' lead time. Your options: our rebuild (8-12 business days), a tested used unit from surplus stock, or an emergency 24-72 hour rush. We give you all three prices in writing. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
Why does my SEW motor run slow or hot after swapping it?
Check star vs delta wiring against the terminal plate — mismatched connection on 4-pole motors running on VFDs at 100Hz is the classic mistake discussed in controls forums. If wiring checks out and it still overheats, the gear end may be binding from bearing wear. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
