We have just fitted four lowara pumps that came with WEG motors (37kW 400V 2 pole) . These motors are controlled by ABB acs 800 active front end drives. Within a week we had lost Three of the four Motors, motors taking very large currents and tripping on overcurrent before they got anywhere near rated speed . pumps free motors even ran uncoupled and still failing. Has anyone else experienced these issues and level of failure with WEG motors , We have now fitted ABB motors to the same drives and pumps and have run for the last 3 weeks non stop.
