Unfortunately a drive built to run off of line AC will generally be approximately the same amount larger as the size power supply you need. Simply because you've stuck the power supply inside the drive. You could try looking for a smaller supply? Can you combine the power supply with any other power source needs in you're machine?
Here is a little 120w 24v one that mounts on a din rail and only takes up about 1.5"x5"x4". (But maybe that isn't any better than you have.) https://www.amazon.com/NVVV-EDR-120-24-24VDC-Industrial-Supplies/dp/B0932X2WHW/ref=sr_1_11?keywords=24v+5a+power+supply&qid=1682435519&s=electronics&sr=1-11 Todd Zuercher P.

What I mean is that specific driver would not fit into my space. I am currently using a custom 24v BLDC driver that I built. But the only option for power supply at this point is a wall wart that is about twice the size of your typical laptop charger, which I'd like to eliminate. > On Apr 25, 2023, at 7:00 AM, Todd Zuercher <to...@pgrahamdunn.com> wrote: > > I'm a little confused, a BLDC motor is still going to need a drive/driver, > weather or not it runs at line voltage, that you say you don't have space > for.
