This is starting to make a lot more sense. With the diagrams and links posted and the information provided I feel confident i can tackle this safely now and also happy i dont have to purchase a new motor!

I seem to have a growing collection of Single Phase Motors as I switch everything out to VFD!

I'll drop some detailed progress pictures in this thread over the coming week or so for anyone in the future who may stumble across this needing the same advice.

Can't thank you all enough.

This Forum is incredible!

Thanks all so much for the quick replies. Im at work now but will digest this info this eve and respond fully.

Thanks so much for the help..

Hello Model Engineers,

I'm looking for some advice regarding a 3 Phase Brook Crompton Motor. The motor is from a Myford ML7RB on an Industrial Cabinet.

I recently purchased a Weg CFW300 VFD and have successfully set it up running a Tec 3 Phase Motor for an emco machine. However the Brook Compton motor i would like to use on the myford (see attached) has a terminal setup im not familiar with. In my (limited) experience, I have set up Tec Motors that are configurable to Star or Delta using the connecting bars in the terminal housing. But this motor does not have that setup.(See Pics Below)

MMB534BS1F282BV

W 370

RPM 1425

V 380/440 - 220/250

A 1.2 2.1

PH 3 HZ 50 RTG.CR

INS.CL F AMB *C Max

BS5000/11

If anyone could offer any advice on the following:

A) is this motor suitable for a VFD?

B) What configuration is this motor, Star or Delta? I will be running the VFD from household single phase supply.

C) How would i go about configuring it to Delta, will it require the motor end sheild fan cover to be removed?

Many thanks in advance for your help.

I did a lo of research and searching before chosing the lathe. The M250 is about the biggest i can fit in my workshop whilst still having plenty of grunt. The machine came out of a secondary school and needed to be stripped, cleaned nd rebuilt but has seen little work in its life so minimal wear. Certainly a few scars from being crashed by young students but runs extremely well. The mill was in a sorrier state. After stripping it to down, cleaning and rebuilding it id say It likely needs to be scraped in but thats beyond my skill level and it certainly does everything i need it to do. It has been a pleasure to operate.

I will have a look into the the Stuart single cylinder vertical steam engine. Im discovering this may become a bit of a wormhole. The poppin sounds like a fun project. certainly got my reading cut out for me.

The shipwrights i do work for are based in east london and predominantly do restorations on barges. One of the more significant projects is on the refurbishment of the reconstructed Golden Hinde. Much of the tooling needed is either extremely hard to come by or expensive to have made. I have machined custom tools for them. Generally the work is fairly simple and revolving around fixtures and fittings. Its a big learning curve and very much a hobby. Any money i make is fed back into the workshop. My goal is that through model engineering i'll gain a better understanding and increased skill in working to critical tolerances.

Many thanks for all the advice.

Many thanks for the link, that looks exactly like what ive been looking for. Best to start with simple and work up to more complex assemblies. What a well explanined website. Yours looks to be very well executed. Do you run it from compressed air? Excuse my basic knowledge, im just starting on this journey so lots to learn!

Hi All,

My name is Paul, I have been reading this forum for a couple of years or so. Lots of wonderful info that has helped me on so many occasions. I find the techniques and discussion here has been extremely valuable for a wide variety of workshop practices. I have been teaching myself machining for about three or four years now and I feel it’s about time to tackle a model engine, something very simple to start with. If anyone has any advice on a good beginners project I’d gladly welcome all suggestions.

I started out learning on a Colchester Student and Bridgeport at in my workplace (a university) and fell in love with machining as a hobby. I bought myself a Myford ML10 for my little home workshop and then quickly snapped up an Astra CST L4 Miller. As my skill evolved and the bug deepened its grip on me i upgraded to a Harrison M250 and restored an Elliot Omnimill. I now have a bad habit for buying old machines and tools, cleaning them up and giving them the love they deserve! currently working on a small Herbert Surface Grinder. 90% of the work i do is for a small team of shipwrights working on restoration and heritage projects on the Thames and South East, the rest is mostly for furniture makers.

So, hello to all and any suggestions for a 1st simple model engine project with easy to follow plans would be gratefully received.

All the best,

Paul.
