I am having trouble with an engine toshiba of 400hp 4 poles this generating a 10x multiple of the engine with the bearing of 100 degrees in the warming and the greater frequency this carcass around the 2.5 khz indocando a frequency of chaveamento the inverter speed of the best solution modify the model and characteristic of the engine or the inverter
motor in extrusora flour.
If necessary sending spectrum of prims4 skf

To judge the bearing temperature:
100 degrees... F or C? Measured where (housing or bearing metal)? What type of bearing and lubrication?

You have 50 hz power? So 4 pole running speed is 25hz and 10x is 250hz? What is the 2.5khz?
If you can attach a spectrum, that would be helpful.
