Inside a Vitamix: a peek under the hood

peeking-in-vitamix-motorThese pictures show the inside of a Vitamix 7500 base. I had it open for my project to understand motor heating. I found it fascinating, and thought some of you may be interested as well.

The complex airflow design presumably maximizes airflow, while trapping as much sound as possible. I also noticed layers of squishy rubber between parts. The rubber dampens vibrations, which presumably helps for both sound and longevity.

Inside a Vitamix: a peek under the hood — 2 Comments

  1. The motor cutaway photos of the 7500 are fine. And very welcome.

    Your website reinforced my previous instinct to buy the 7500. I sent my container to Vitamix on a recall and it was never returned. Is this common? I bought a replacement identical container because of comments on the internet that Vitamix service is dog slow. My container was a stock 4-inch blade low boy 64 oz. container.

    • Did you call Vitamix customer service? In my experience, that is the best way to deal with them and they always make things right. That blade recall was over 3 years ago, so I’m not sure what they’d do if you called them now, but I wouldn’t be surprised if they send you another container.
