Morning All
We were called to a motor on a printing press yesterday, basically it had burnt out.
The press is on a transformer and is supplied by 200V 3 phase.
When we checked the motor connections against the data plate it seemed to us that the motor had been conneted incorrectly (i.e direct on line connected in star rather than delta) and so the voltage was wrong.
We've connected the replacement motor in delta and it seems to be running fine
What happens in these circumstances when a motor is connected up incorrectly because the old one lasted 18 months
