Ok will do that when my son collects them for me. CheersMeasure the resistance of the coil and that will tell you how many amps it will pull at 24v
Did you have the manufactured phase connected to your control circuit?Ok i solved it......for the record 2 of the phases were reversed. It works great now.
Even the 24 volt runs....just got to wire up switches...mount transformer and tidy of wiring and i can cut some swarf.... lol
Dont know mate... 3 wires come out of the converter and go to the main contactor....i just switched number one with number 2 and it runs...what do you mean by control circuit?Did you have the manufactured phase connected to your control circuit?
I got a call at 5.30...did you manage to fix the lathe dad.....ok i will be round in a minute. DohOk i solved it......for the record 2 of the phases were reversed. It works great now.

Ah i see no. Its now wired with a 240 volt transformer supplying 24 volts to hold the contactor in as a temp measure...so its not that..Normally one of the phases, is used to operate the control circuit, ie pull in the hold on coil or the relays in the contactors. If the manufactured phase ie sy the 100 volt one is supplying this it doesnt work, making odd noises as you said. Swapping the phases corrected this.
quick question thats bugging me. Seems I have read somewhere that if a 5 HP motor runs fine a 3 phase static converter a 1.5HP drill will not run correctly ...but I cant find it again. Am I dreaming or not?
Mine has a 4 Way switch and i have 3 small AC panel meters coming so i can leave then connected. I still have to finish the wiring on the lathe so i might fit them to the front of the static box so i can see how its balancing on each pole of the switch.probably right - the capacitor that makes the third phase is different values for different loads - a lot of static converters have switches to select the capacitor(s) for specific loads, e.g. 1/2, 1, 2 HP and you add them so you'd switch in for 1/2 and 1 if your motor was 1&1/2HP.
Same's true but less so for rotary convertors, the balance capacitors depend on load to get matched voltages on the three phases - but the motor will produce pretty usable 3-phase without, just don't try running proper electronics off it without balancing caps.
