My 2 Year Old $2500 Compressor Just Died

Thanks for the idea. I am wondering if 45 minutes on and 10 or 15 off would help. I'll ask the motor repair guy when I pick the new motor up from him after I have him tweak it.

I never saw a electric motor broken in during my 20 plus years in power gen other than running for several minutes with no load while a electrician checked it and even that on board the ship, mechanics replaced a motor, did the coupling alignment while the electrician wired it, started it, checked for proper rotation and than on line.....Motors are checked before they are run.
The amount of use your compressor gets would dictate how HD a motor and pump you have......A hour indicator would help .....I think in the end you got a crap motor and had the bad luck of it failing
What I did see in large industrial motors was waiting a specific time after shutting one down before starting again......Its the starts and stops and the load of course
