Customer replaced 3 ph 3/4 hp 860 rpm motor yesterday without looking for the cause of failure. Typical. They burnt up the second motor within a short time. These motors may be common for some of you, but not here. Short term solution would be VFD on a 1750 rpm but once that is installed they will run it until death do us part. Will the VFD give me the constant torqe I want at that speed for long term? Assume drive rated motor because they all seem to be that way anymore.
