Tristar CS question

[ctvacman]

I recently won a basically new CS off eBay orig box manual tools etc... Literally was not used, upon turning it on I couldn't help but wonder if it really had the brushless motor. It did not do the slow start thing when turned on and it has the same pitch I found annoying on my guardian ultra. It's slightly quieter since it's made of metal, but still kinda pitchy.

So I guess I'm wondering if all CS's had the brushless motor or was it added awhile later. I have pictures of the motor. I looked closely and couldn't see brushes but then again I'm not an expert on this brand.

Unfortunately

I do not have a dealer near by otherwise I would have purchased from them, assuming the price is good.

I'm no expert either, but that looks just like a regular brushed Amtek motor, only I don't see any wires running to where the carbons would be?

 

[ctvacman]

Exactly

I didn't see wires either, that's what made me think that yes it is brushless. Didn't really take the motor out to look at another angle.

If it's like the Electrolux / Aerus motors the carbon brush is in a plastic housing in the plastic bridge over the end of the armature. There are no wires to the brushes, there is a spring underneath that makes the contact to the brush assembly.

The TriStar CS motor is NOT a brushless motor. It is made by Johnson Electric, & it does use carbon brushes. If you look under the motor field coil, you will see the brushes. It's very similar in design to a Domel motor & the Miele Vortex motor. A fellow member & close friend, Piano_God, has referenced to it's design a couple of times in postings here on Vacuumland.

Brushless motors need a circuit board to operate them-no board in there!

Kirbylux and tolivac

Thanks for the clarification. I thought they needed a circuit board to operate.

Kinda pissed that many people on here said the CS is a brushless motor.

As far as I'm aware of, only two currently available portable vacuum cleaners made for domestic use have brushless switched reluctance motors. The newest model Delphin and the Rainbow. The now obsolete Dyson DC22 used a brushless motor as well, but I don't believe they sold well. The Dyson STICK VACS have brushless motors in them - but of course are not full size vacuums.

Just wondering....which motor manufacturer is making the Rainbow & Delphin switched-reluctance motors? Ametek Italia? And are they identical specs in regards to Waterlift & CFM ratings?

I was aware of those models using them. You're right the dyson dc22 did not sell well due to its tiny size and almost $800 price tag. I just read so many people on here saying the CS used a brushless motor, I was hesitant but believed it anyways. Oh well.

Tristar is made in the same plant as Aerus, they share parts in common, so I don't understand why anyone would think they use a brushless motor.

 

[ctvacman]

Exactly

That's what I thought was odd as well. Aerus would certainly use a brushless motor as well

Hi Rob, rexair makes their own brushless motors for the rainbow.

Rexair

Cool..not another "assembled in America with globally sourced components"...

 

[dysonman1]

Actually Rick A.:

That's not quite the case. You see, some of the Rexair brushless motor components are made in China. Evan Rogers showed me the Rainbow motor's rotor (we used to call it the armature), and it was plainly stamped Made In China. Rexair buys parts from suppliers just like everyone else.

Tom

Where would china be stamped on the rotor?

 

[dysonman1]

On the packaging that the new Rotor comes in from Rexair.
