Motor Overloading Problem
Hope you are in good health, I am coming across an issue on one of my systems, need your insight on this.
We were running 90KW, 1480rpm, 380 Volts motor but due to increased flow requirements, we increased its rpm to 1800, but as a results it temperature increased and motor started to fail.
Therefore we installed, 90KW, 2900rpm, 380 Volts motor on the same location, but now we are unable to increase rpm beyond 850, as its load is 100% at this point.
Please share what could be the possible cause, as per Andritz (pump supplier) same pump should run on 2900.
I have ACS800-04-0120-3+J400+L503 drive installed on it.
I look forward to your expert opinion.
