one or two stage motors

[n0oxy]

I'm wondering if the motors used in certain vacuum models were one or two stage, they sound like two stage but thought I would ask. Electrolux 1205, Electrolux Olympia, and the Ametek motors that were used in the Eureka canned ham and Airway models of the 1950's and 1960's. It seems that two stage motors are becoming less and less common now which is why most current vacuums sound like screamer jets. The motors in vacuums such as the 1205 and canned ham sounded much more pleasant.

most

were two stage fans. I light of lower cost motors, extra windings were added for more speed on single fan motors above 11 amps draw to compensate. They were noisier. Then came sound insulation, and then canted blade vortex fans, which do move a lot of air.

I do enjoy the sound of my Silverado, but the Miele isn't bad either.

I have an E-Lux

XXX. A Miele is on my bucket list. Hubby won't let me hoard though, so before that happens, I'd have to dump one or two. It's not like I have ten. Only five, not counting the built in.
A pawn shop 5 miles up the road had a very nice C2 green Jasper for $50. The older model, with the power port for the elctro brush, which it also had, but the add said it wasn't operating. From the good photos, it looked like whom ever pawned it put a non electric hose on it. They likley had two Mieles, and kept the extra electric hose, which they must have bought after the initial purhcase. The power brush looked like the SEB 25. So maybe it needed a new hose only.
When I said I was going to get it, guess who said No? We don't need any more of those around!

Single fan motors were used by Sears and Eureka, starting in the very early 1960's. Lamb made them for the 'cheaper' models, such as Eureka's new "princess" line. These single fan motors ran much faster, resulting in shorter lift as compared to slower running twin-fan models. Whirlpool jumped on the single fan motor bandwagon for the cheapest Kenmore models as well.
