Controlling your toy's
As discussed recently here are some pics of the control unit for my lathe
It is an Emerson Commander SK. This one is capable of running 1.5KW (2HP)
Pic 1/ The unit located on my left hand - out of the way but easily accessed.
Pic 2/ The control head. I purchase a std electrical box, some flash switches and pots and made a very functional but basic control head.
It has a "Go" or "On" push button, a "step" push button which allows you step through a pre-defined cycle.
The big red "stop" button is a locking off for safety and features instant stop with braking.
The "Forward / reverse" control is just that the and "Speed" control adjusts the speed from 0 to flat out. This motor is a 1385 RPM
Pic 3/ The control unit. It is just screwed to the wall - out of the crap and harms way, with plenty of cooling room. The unit has an inbuilt fan which fires up occaisionally.
This outfit cost me a little over $400, but I had some assistance sourcing it. Not sure what they run out at now - can find out if anyone is interested. My sparky is now in Qld.
Pic 4/ Motor - probably a bit big for this lathe but quiet and cheap!
I have the PDF of the user guide if interested. Unit has heaps of other 'stuff' it can do and can be integrated to PC ?? CNC
I know in researching this that there are a number of alternatives and I recently heard of a means to run a three phase off single phase using large capacitors - waiting on a diagram for that - other users may have already encounted this.
Basically you just need a 3 phase motor with Delta windings and that the Delta windings are 240V not 415V. Most motor rewinders can rewire for a nominal cost but there are heaps of 3 phase motors around.
Pic 5/ - Something different! Found this baby in a paddock last week Huge radial arm drill. Very old flat belt driven (Probably steam) and very weathered. Bevan & Edward made in Melb. I think Not sure if it all turns but....
Next challenge is how to lift and transport it!
