Mark,

I was merely saying that the following statement is wrong:

“It takes voltage in that is 180° phased, and shifts to 120° phased”

No phase converter does this. A static converter (I doubt anyone here uses one) does create a phase shifted (delayed) signal to start a 3 ph motor but it still does not take 180 deg phase voltage and shifts to 120 degrees.

Re: AD941 dust hose attachment

 

I have the Felder 90-degree 120mm to 120mm hose elbow. I bought 120mm hose so didn't need an adapter. My only complaint with the Feldor elbow is that it is a "hard" 90, nothing at all sweeping about it.?

Re: P coupling Felder adapter to Hammer

 

Thanks for the responses, I have come across your parallel fence which is very nice but unfortunately haven't been able to afford them including the shipping as im based in Aus. The one from Felder is in country and interestingly enough a little cheaper per unit price but its not a DRO.

Hi Bram thanks for your suggestion, ive found some other forum posts of people using aluminum extrusion and other things such as incra positioners, rulers etc which seem to function quiet well without adding too much lateral weight bearing on the t-slot.

Thanks,

Above may be true for you but just want to be sure that you have gone thru the mechanics. The right angle adapter works great for me both in jointer and planer modes. It routes the hose just as I would like. Even though mine is dual 51 concept is same. I use 2 separate hoses (thanks to David Best) for jointer and planer and both are standard 5” spiral hoses.

Re: 3 phase power plugs/outlets

?Mark,

“A phase convertor manufactures a phase shift, not a voltage change.? It takes voltage in that is 180° phased, and shifts to 120° phased, basically by storing electrons for 60° of time, and then releasing them.”

As you know, 180° phase relationship only exists between the two 120 Vac lines due to the center tap on transformer. Any phase converter whether?Rotary Phase Converter or Digital converter (Phase Perfect) or VFD running on single phase input does not care nor are they affected by this?180° phase relationship.

The idea of delaying a signal (phase shift) is valid though; that is how I, and presumably others, start the 3 phase idle motor of the RPC from single phase.

Europe started electrification later than the US, and by that time, 230v was understood to be a better choice.? It's a lot like metric vs imperial vs whitworth.

That said, two physics principles warrant pointing out.? First, three phase motors are superior to single phase? -- more efficient, self-starting, smoother.? ?Four phase or six phase or eleven phase (all real things) motors are smoother yet, but for various practical/cost reasons, 3 phases was the most practical early on, and became the common industrial standard, in parallel to the 110v single phase standard for lighting that began
<IMG_3207.HEIC>
Edison. The second basic physics is that higher voltage allows smaller conductors.? So the higher the wattage (total power), the higher the voltage you want, in order to minimize the wire/infrastructure cost.? ?At 250,000 volts, the wire size you use on your Felder saw could power a neighborhood.

So generators (hydro dams, coal-fired, etc) produce three phase at very high voltages (250kv), and it gets transformed down to "usable" voltages the nearer it gets to the point of use.? At my day job we get 12kv from the utility, which we transform down on-premise to various voltages, ultimately to 120v for "consumer" devices.? But most small/medium industrial users get 600v, because above that it's more complicated to manage.? ?Once you get much above 600v, air is a conductor, so for example breakers have to have operate in a vacuum, or other such complexities.? ?You don't casually turn things on and off that operate at kV levels.? So although you might save money on smaller wire by having 2,000v motors vs 600v motors, you pay a premium in other other ways for higher voltage.? We have more electrical safety personnel than electricians doing electrical work.

So to Brett's point, every industrial facility needs both 3 phase (for motors, etc) but also has toasters and coffee pots.? And so electrical distribution systems evolved to conveniently supply both the local standard 3P voltages (600, 500, 480, 460, 400, 240..) and the standard single phase voltages (120 or 230 almost everywhere.)? It's very simple to get any voltage off a transformer, it's really nothing more than the number of wire windings.??

To Brett's comment that neutral is "manufactured".? Well, every output of a transformer is "manufactured".? That's what a transformer does.? It's a device to manufacture some voltage different than the input voltage.? So if you have a transformer with 600v input, and you tap 240v out, and also 120v out, they are both manufactured.? ?But it's correct that it's always the last step, for practical purposes.? If you step down to 120v a mile away from the point of usage, the conductors to go the "last mile" are impractically large and expensive.? So typically a residential power pole is carrying ~5kV until the transformer that you see on the pole outside your house, which steps down to residential voltages.

In this sense, "manufactured" is different than this word is most often used on FOG, ie, in relation to phase convertors.? A phase convertor manufactures a phase shift, not a voltage change.? It takes voltage in that is 180° phased, and shifts to 120° phased, basically by storing electrons for 60° of time, and then releasing them.? ?

To illustrate the independence of phasing and voltage, here's one of my three phase motors.? It's 5V.

Wouldn’t a straight connector offer better air flow (less turbulent flow)? ?That might be important given that your ducting is undersized...

Imran,

Thank you. ?

Bill does offer a 120mm to 4” hose. See link.
But it’s not a right angle. ?

Now if he offered a 120mm O.D. to machine connection, then it curved 90 degrees to an end that excepts a 4” hose, well then FOR ME that would be the “Holy Grail” of adapters! ?

Wade,

I use 5” spiral with Felder adapter and I assume Bill Belanger adapter does the same. Which ever way you go, just confirm that the hose end matches your requirement.

Imran,

Great point about clearing the hose out of the path of outfeed. ?I’d like to go with the right angle adapter setup, but I’m also wanting to keep my hose size to the 4”+ that it is. ?

Above may be true for you but just want to be sure that you have gone thru the mechanics. The right angle adapter works great for me both in jointer and planer modes. It routes the hose just as I would like. Even though mine is dual 51 concept is same. I use 2 separate hoses (thanks to David Best) for jointer and planer and both are standard 5” spiral hoses.

The pics illustrate the benefit to me for the right angle connector.

?Jointer:

Planer: This is important because you want the hose to go up, otherwise it will be in the path of outfeed.

Hi Bob Wise,

I’m just connecting flex ducting that has the reinforced spiral wire that coils through it. Wanting to make a direct attachment. ?

Some have mentioned they use Felder’s right angle adapter, but I don’t see the need on my situation to use a right angle adapter. ?Just a straight tapered adapter would suffice. ?

Thx,

Wade
