Thread: NEMA selection for electronic leadscrew
04/03/2020 16:16:40

The power supply for stepper motors is an important consideration. I have a NEMA 24 4Nm stepper directly driving the Z axis on my Champion V20 mill. I use a 40volt DC home made linear power supply and the system has more than enough power to lift the head without any other assistance.

Is it right to use land to produce biofuels when over 800 million people in the world are going hungry?

Russell

The move to biofuels is a good example of the law of unintended consequenses.

Andrew, Yes indeed. looks like a late 1970s model. You can tell the age from the serial no. - month and year then a sequential number for that year. We've still got the records of almost all the units we have ever made since about 1960.

Thank you so much for the warm welcome.
Harry, I worked for a company called Carbolite Furnaces. When I joined them in 1968 they were based in an old mill by the side of the river Derwent at Bamford in the Hope Valley. It was a magic place! We had a fully operational stationary steam engine to play with. The company preserved it when all the cotton related equipment was removed. We used to run it on the last friday of every month and people came from far and wide to see it. We had steam turbine and big DC generators as well but these were not operational. And of course we also had to water turbines driving a 30kW alternator, it provided us with enough electricity during the 3 day week saga back in the early 70s. The company moved to a custom built factory in 1993 and the mill was turned into posh apartments. As far as I know the steam engine is still there but no longer operational, I was told they were struggling to find someone to look after it. I joined the company while I decided what I actually wanted to do and left 51 years later!

Hello, my name is Peter and I live in Chesterfield in Derbyshire. I think I am more a hobby engineer than a model engineer but having followed the exploits of Ron Laden from the very beginning he has inspired me to have a go at building a simple model steam engine. I am building an engine based on the E-Z engine from homemodelenginemachinist.com. I enjoy making tooling and bits and pieces for my machines and it is surprising just how useful a lathe is to support all sorts of other interests. I acquired for a nominal sum a lathe and a pillar drill about 30 years ago when my employer was having a factory clear out. I knew nothing about them then but quite fancied learning. Doing a bit of investigation when I got them home I discovered I was to be the proud owner of a Myford Super 7 and a Fobco Star bench pillar drill. The Super 7 is 1959 vintage and I guess the drill is a similar age. They are both in remarkably good condition for 60+ years old! When I fully retired recently these were joined by a Chester V20 milling machine. Another current project is motorising the Z axis on the V20 with a stepper motor and Arduino. Similar to the article in the latest MEW but easier because the manual handle is on the side and the motor connects to the top of the leadscrew.

My background is electrical engineering and electronics though I have spent most of my working life around industrial electric ovens and furnaces. Having gleaned so much from this forum, hopefully I can contribute some thoughts on temperature related matters.

Best regards Peter G1UGL
