Hi and welcome to the forum the Report button is to allow a member to report any post to site admin if they see something within a post that may require their attention.Yes no part three.What does report mean?
Have many watched this and have made this or something similar?
As far as the converter goes I am at the moment not too convinced on some of the theory behind this project, I would be very interested to see the nuts and bolt of this in operation. In particular voltages around, you can't get something for nothing.
This is the bit i am struggling with, i know they build converters with pilot motors to run the main motor up often in the USA.It seems sound enough. You start the slave motor using two windings and then once up to speed, you switch it over to (and keep it running on) one winding. It generates the missing two phases
Onoff what voltage do you end up with?Are you still in touch with the guy and is he going to make third video?
When you get a transformer it might be worth removing the plug and hard wiring, just in case someone tries to use the transformer for its original purpose.??? Different bloke. My mate who made the one with the 110 plug on the board never made a video. Tbh I've never had it running. Need to convert a 110 tranny etc.

Do you mean it comes to a stop rather than accelerating up to speed?This is the bit i am struggling with, i know they build converters with pilot motors to run the main motor up often in the USA.
But even once brought up to speed with the single phase motor, that stops once the big one is running, i am struggling to see how you spin a 17hp motor and keep it running with 230v across one winding only, i know there must be caps in the circuit that he hasn't shown in the diagram.
I am used to working with converters and motors and am fully aware of startup loads, even a true 3 phase motor will often stall if one phase goes down while it is running.
The building of the rotary converter to produce 230v three phase I now think I understand and can build but bringing it up to 415 with a step up transformer I don't.Could anyone help me with this or point me to a post which explains it clearly,I am not great with circuit diagrams.Has anyone used a welder transformer for this and could show how they did it?
Mine are some thing like 426 to 440 idling and all of them were 426 under what ever load it was IGot a transformer and have got the rotary converter up and running.Under load the voltages are 419,396 and 389 would this be considered too far out of balance for a rotary converter?

Post #8 above, it's a modified 110V trannie that feeds it. Rewired to get nom 340V out. A bit low but the mate I got the rig off said it ran his saw fine.
