Managed to steal a couple of hours today and made a start on my rotary phase converter.
The 7.5hp motor I bought on the weekend had a big cast impeller of some strange sort on the output shaft
Fortunately whoever made this thing foresaw the need for it to come off one day, there are a couple of M12 threaded puller holes in the casting
Turns out a 42mm shaft has a lot of holding power, my oxy set is just about out of gas so I didn't want to blow it all away warming this thing up, used the small propane torch to warm up around the bore (this thing is one big heat sink, didn't want to warm up in a hurry) anyway after nearly busting both my puller and my pooper valve, the thing eventually moved
Got back to the jobs I was supposed to be doing for the rest of the afternoon, then stole a bit more time to make a stand for the phase converter. The motor will stand vertically in this frame, with the flange bolted down to the lower cross members. The cabinet with the electrickery will sit on top. Have to make some screw feet for it yet and some threaded bushes, the bushes will be welded to the lower cross members to accept the flange bolts. Nearly 6 meters (20 feet) of 40x40x2mm RHS in this thing.
The 240 to 415v transformer and all the capacitors etc should be here by the time we get back from our outback trip in a couple of weeks. Unfortunately it will be time for me to go back to work then too, don't know how I find the time to have a full-time job.
