For UK use:

anyone used dyson motors. they are pretty cheap from ebay. £13.00 pounds new.

1600w/240v

the two stage amtek motors @ 1000w are alot expensive at £50 each.

Flow Chart for the Dyson motors?

I couldn't find a chart for the Dyson or Electrolux in the past, post a link if you find one

For that money I might buy one and test it what is that like $23 US, not trying to be flipit just sounds like a deal for a motor do you have a link to the sale?

Maybe can help, the basis of comparison is 1600W, and watch the air intake hole.
I think it's double turbine to reach 1600W.

If Hotz chart is for the same motor, it reads well. 115cfm @44" Lots of amps though....

Keep in mind that we tend to think about motors as used in the PTS Design and the motors are going to work different if you have a big ole fan device sitting in the airstream measuring airspeed. There is going to need to be some R&D for a DIY design picking motors.

Just putting that thought out there . . .

It is not specific the Dyson motor.
But for a long time I observed in my studies to find out nearest to Ametek motors.
My engines are Electrolux 1600W and using metric system as your tax basis is only specified in Watts.
The chart I posted gave me a rough idea, and there is a parity between manufacturers (standard) one thing is certain Ametek motors has a very wide range of application models and that helps a lot to FB design, the other fewer manufacturers options.

A relevant detail is that the ability of our friend damunk want to achieve with your FlowBenck.
1600W engines have a great power and reaches easily 400CFM in PTS design.

With thermal cut out. So I'm guessing no danger of overheating to extent of blow out.

My thoughts too.
Only a miserable 8 CFM per amp.
A good motor should do 16 CFM per amp.

As Jim says, they will deliver the air o/k, but you are going to need to have massive electrical power available to drive them.
