Hi Guys
I have almost finished building my RPC.
I have just found out our power supply company has a limit on starting motors direct online of over 4kw due to voltage drop affecting neighbors etc.
I have a 7.5kw lathe motor I would like to run. The RPC I am building uses 4 x 2.5kw motors that will be started using a staggered start to reduce in rush overload.
I was under the impression that when the 7.5kw motor was started the 10kw of motors already rotating would help buffer the the in rush drawn from the utility? with the motors acting like an electrical flywheel, am I mistaken?
The other thing to add is that I have 2 of the 3 phases and a neutral already present so am just using the idler motors to generate the third phase.
