I have a Bamix stick blender. I was looking to replace an accessory and lit on this description of the machine:

The Bamix DeLuxe has a 160W dual-speed (commercial grade) induction motor, which is supplied with a 5-year guarantee and has operating speeds of 10,000 and 15,000 revolutions per minute.

That challenged my idea of of how an induction motor works - can this be true?

It certainly works well and blends better than the last cheapo one which boasted an 800W motor (enough to power a small lathe!), but burned out within 4 months

Robin,

The Bamix motors that I've seen, have brushes ... and are therefore not 'induction motors'

... Where did you find that description of the machine ?

.

Edit: I've just searched for the quoted text, and its use is widespread

... That does not, of course, guarantee its accuracy.

I was going to suggest that it might be a brushless DC motor, but I think Michael has the answer.

That Youtube video indicates to me that The motor is no better and no different than any other similar blender and that the bearing and material choices are not those that a quality manufacturer would choose. Why do companies extol the design flaws of their products?

Note:- I'm not saying that it isn't manufactured and assembled to better tolerances than the rest of the competition, just that the design is no better and may be poorer in some details.

It is hand-made in Switzerland and does have sarded copper wire connections though.

I think we are on at least the 4th stick blender. I don't think the motor or its bearings have ever given a problem - it's usually the switches or the coupling where the accessories fit.

MichaelG, thanks for the link- I had assumed from the confident and specific wording that the description came from Bamix themselves rather than being something a reseller had dreamed up, but obviously not. Perhaps it's a lazy translation of 'AC motor'. Anyhow, I shall sleep the easier for knowing that it's not some groundbreaking technology I hadn't heard of.

On my over-long 'get around tuit' list is a mixing head to attach to a woodworking router along these lines: **LINK** . I used these things when I was an R&D chemist for a coatings firm, and they are extremely good at emulsifying liquids and breaking down fibrous materials. It's all in the head design - getting the Watts into shearing rather than swishing liquid around. Overkill for the kitchen you may think, but I eat a lot of curry!

I have a special way of gripping the body of mine to stop the whisk attachment waltzing across the kitchen

I'm not comfortable with the fact you might want to share that with us Neil surprise

Does it involve wet celery and a flying helmet?

I find anything on electric motors useful. But can somebody enlighten me ? What is a stick blender and why do you want to blend sticks ?
