I think Sears had a contractor’s saw one time that had a cast iron table and a universal direct drive motor.
They tried to promote the direct drive as an advantage stating things like high efficiency and no belts to get loose and things like that. They also claimed it was a 3hp saw, which is obviously BS, since it ran on a standard 120volt outlet.
Most people must have seen this marketing ploy for what it was, a way to sell a cheap universal motor in a table saw, and stayed away because they dropped the campain about as fast as it popped up.

In answer to your question, all direct drive saws hang the blade directly on the motor shaft and use universal, brush type motors. There are a few really well respected saws that use this design, like the Bosch, Dewalt, Ridgid, Porter Cable etc. jobsite type saws, and they are good saws, but cost almost the same as the hybrid class cabinet saws; about $500 to $600. Their main purpose is to be portable.
Much more common in the direct drive saw genre are the $100 to $200 Ryobies and Skil, and generic labeled variations. These saws serve a market where longevity is not a primary concern. They work, but they don’t have the bearings and beef to hold up to continuous professional use.

A table saw with a cast iron table, standard miter slots, belt drive induction motor is just a much more stable and quiter, and longer lasting option.
