Note: I am busy learning about 3 phase alternators. A lot of my understanding is theory so I'm running through scenario's for better understanding.
Lets say we have a 2KW-220V-50Hz 3 phase alternator with 3 live wires and no ground. The voltage between phases are 220V.
We decide that we want to power a 180W induction bench motor and 3x100W light bulbs (480W load) from one of the phases of the alternator.
We know that the 2KW alternator is 80% efficient, So we should be able to safely draw 1600Watts from the combined phases and 533W maximum per phase.
My questions are:
- Are 3 phase alternators tolerant of drawing power from only one phase ?
- Will drawing from one phase cause the alternator to vibrate more ?
- Could drawing from one phase cause the alternator to wear out faster ?
