i bought a 3 phase 18.5kw motor ,weighs 104kgs, rpm 1455, could i get it to run on 240volt single phase without blowing the house electricity supply up? well yes, needed a 'run up' with a 1.5kw motor to get the speed upto 800rpm, switch the power on...........and............well it ran and only pulled 3kw under no load! might convert it into a rotary phase converter. the motor is a GEC 18.5kw, 35.5 amps , volts 415,

I show in detail three different methods for powering a three-phase motor with single phase power. I show all the parts, how they work together, and the pros and cons of each method. The goal is to also explain how it works, not just “put the wires here”.

1. Potential relays come in different ratings. So, you have to be sure you get one that matches the voltage of your motor. The one I show in the video says is is for "any potential" as long as the motor is rated for 120, or 240. Details in the link below.
