    Can you use a single phase motor to create three phase power.

    This might sound like a stupid question so apologies in advance. So I had a random thought in my head. So I was wondering if I was to use a single phase motor to spin a three phase generator to create three phase power, would you be able to create more power then the single phase motor is...

    Can I Just replace a 3phase motor with a single phase on my lathe?

    I have a metal lathe, 1.5hp, 3phase, 575v motor. Can I just replace the motor with a single phase,220v motor? Would all the lathe wiring , switches, relays work? IF so, what HP motor should I buy? Thanks,

    I need help with how inductance works in a single phase transformer

    I currently have this, Primary inductance on an AC transformer will determine the magnetizing current on the unit. Usually inductance is relatively high so the magnetizing current can be as equally low. This inductance can be seen as part of the magnetizing current; however, it will not be seen...

    Can you use this 3 phase device on single phase

    Hi there I purchased goods to build a sauna back before Christmas and only now am I getting around to doing it. I was just looking at the heater controller and noticed they they’ve sold me a unit that says it is for a 3 phase/400v supply. I did make clear I only had single phase as many...

    As title. Doing an EICR, have come across a couple of DBs, where the neutral goes straight onto the bar on Single phase boards. Whats your views on this guys? Should it have a requirement to be isolated? Is there a reg for? If so then it can be coded. My boss thinks its dangerous. I don't, but...

    3 phase domestic supply

    I watched this vid on Youtube. Interesting. They have 3 phase supplies. Does anyone know the cost of upgrading from a single to a 3 phase domestic supply? View: https://www.youtube.com/watch?v=uI7wxNtrorQ&lc=UgyPTN2d89tBByfm4Dx4AaABAg.9CrcYe7x50b9CsC6DnPJKw
