A standard practice in saw design is to use induction motor with belt drive on larger saws and universal motor with direct (or gear) drive on compact saws due to weight, longevity, and other consideration.
Take a look at these old (1980s) compact saw motors:

Sears Craftsman 10” Table Saw model 113.298050
(if this link expires, you can see diagram of model 113.298050 here

Delta Rockwell 34-570/580 Table Saw

These are 3000-4000 rpm motors and look like induction (brushless) type. The blade mounts directly on the motor shaft. It seems that such an arrangement would suffer from lack of torque. Am I correct? If these are in fact induction motors and they do work well, why nobody uses them on small saws these days?

I have used the Sears saw motor. It is certainly not a 3 hp powermatic but it is better than most of the bench saws we see today. Sears sold this for severqal years. I never met a person that had used one that didn’t like it. Now with that said I think these people realized what they had and didn’t try to rip 4 inch beams on it. These were good light weight saws. for what it is worth

Have your say...
