Hi all. I'm looking to build myself a rig with a small single phase motor and learn a bit more about motor controls etc. I mostly do domestic and some commercial but haven't much experience with motor controls. I always looks at ways to improve myself and my electrical knowledge. Most DOL starters would be pre wired so i take it there wouldn't be much to be gained from that. So would i be better buying NO & NC Switches, Contactor and overload and building it that way? Also looking for advice with regards to contacts 97/98 on the overload. Again, this is not a job or anything like that, this is solely for the purpose of building a rig to give me a better understanding. Any guidance and advice would be very much appreciated. Thanks

There are plenty. Something basic for starters (no pun). My learning books aren't available these days.
It's a very wide and complicated subject, certainly for beginners.
Even beginning, before you start 'speccing' materials, read and get to know fundamentals. You can read about motor control but, starting from scratch, you'll need some help. It could be dangerous, remember, so building live rigs, at home, I would not recommend.
A workshop of some sort, maybe?
Good luck.

I understand where your coming from, like I say I'm not a novice to electrical work,I do mostly domestic & some commercial stuff.

And this is also a reason why I'm trying get a better grasp of this type of electrical work. I think if I have to spend one more day crawling around in someone's loft I'm gonna genuinely crack up.

Ok mate.
Have a look at 'HSE electrical' on YouTube 'dol wiring diagram'. From what I can see, they describe pretty well for single and 3phase.

Might take a bit of a while...but if you catch on, who knows.
Variable speed inverters next.....a bit different to all the different types of starting methods employed in the past.

So am I right in thinking that with a smaller starter,the control circuit won't need it's own protection where as once you start getting bigger,the control circuit would have its own circuit protection?

Self contained DOL starters don't have any lower rated fusing for the control circuit, but once you start adding external start and stop switching, it's usual to add fusing for them, assuming the breaker suppling the starter is too big for the wire used for the control circuit.
Often a 'slidelock' type fuse is used, suspended by the wiring inside the starter case.

I found this one (amongst many others). What do you think of this wiring? I believe that the maker of this video is from overseas, and i know some of our electrical practices do differ.
