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.

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?
