I am looking for a bit of advice, before I go off spending lots of money which may not solve a problem. I know if you put enough money into a project anything is possible, but I am looking for a cost effective way of solving the issue using the parts I have.
I have a diving compressor with electronic control panel. The panel and motor are 3 phase and the motor is 7.5kva 14 amp motor.
The control panel has a star delta starter configuration.
My issue is my intended power supply is not suitable (which was a tractor pto generator, but the old voltage regulator has burn out).
This leaves me with a dilemma.
My other options are:
1: Buy a much larger generator which can handle the torque for starting the motor (I know these motors can take 300% or running power), but this option can get very costly due to the generator size and this would need to be housed somewhere secure
2: Get a new new PTO generator (cheaper option) but my tractor is only 18-20hp, so maximum output would be 10Kva. But this would mean I can move the generator easily and I have a tractor!
3: I can scrap the 3 phase motor and simply bolt of a petrol engine, but this defeats the point of have a control panel with with auto start/stop and automatic drains etc...
4: Replace the 3 phase motor with a single phase with a higher Horse power (this means the control panel will be no good as it is wired for 3 phase)
I was hoping a variable frequency drive or soft starts my help with a lower power generator or tractor pto which would only produce 10kva!
Any advice would be greatfully taken
