It turns out you can with a few add ons
BUT it's an inappropriate way to get more speed out of a DC SP motor, and doing so will lead to serious problems

You might want to read this, Fletty's new shed WIP ....or is it a retrospective?? to see what might happen

They are also in the middle of planning a shed expansion but not much will happen until next year. I have been asked about increasing the capacity of the DC system and will recommend a VFD will be needed.

This, just recommending the addition of a VFD, I don't really follow.

Yes, I get the bit about lower starting current and variable motor speed, but I would think a shed expansion and DC system upgrade would be code to go proper industrial -- 12" or bigger ducting and a 3-ph motor in the range of 10 to 15 kW -- and possible multiple DC units.

I just came back from a shed upgrade planning meeting.
No additional WW machinery is planned.
The existing 7 x 14 m mainly woodshop machinery area and existing DC system will be retained.
The metal working lathe, an upright metal bandsaw, and metal milling machine currently in that area will be replaced by more layout / bench space

Funds permitting, the proposed extension space is going to be for extra office space, bigger social spaces, replacing the Seatainer with a proper storeroom, a spray booth and more metal working space, like welding booths. The latter two will have their own air handling systems.

Were is this mens shed getting their money.....

Ha - must be friends in high places. I'm not involved in the fund raising but there are some members that are decidedly good fundraisers.
I think their plans may be significantly greater than their ability to raise money but I duly stand ready to be corrected

Although, I'm pretty sure that the Teco motor I got for my Clearvue could be wired either 3 phase or single. Maybe I'm confused this is outside my area of interest and experience. One of the other guys will know I'm sure.

It can be wired for either 240/415 volts but not single phase.

Just add another Clearvue, way more simple and cheaper.

Men's Sheds are very well funded, make your case and the money is handed over.

Got some info today and the Laguna C- Flux cyclone single phase motor has been changed for Aus distribution to a 240VAC 50Hz rated unit.

cheers

Yep. The issue is that it runs at 50 Hz instead of 60 Hz. Therefore 20% less airflow than at 60 Hz. Unless they've put a far larger impeller on than the US version, which I highly doubt and thought I remember seeing 15.5" specified for both.

I guess that is a universal issue if the product is USA /Canada based unless made here or in Europe......

are there any serious home workshop based cyclones made in Aus? Or in Europe exported to here?

cheers

I read, on a US forum, that a guy had a DC that was avaiable world wide. He sourced an impellor designed for the 50hz motors to fit to his 60hz as the impellor was larger but casing was the same size.
Maybe that's only the case in some units?

I've been down the exact same path you are on now with cyclones and in the end I went with the clearvue unit and I'm happy I did so.

The performance of the cyclones I looked at when trying to decide were ok but they have nothing on the airflow that the clearvue has... The only plus to them was they were quiet.

A Clearvue Max?
