Most table saws - other than small bench top models - are equipped with induction type motors in the 1 - 5 HP range. On larger saws, you'll most often find a "totally enclosed, fan cooled" (TEFC) induction motor. A TEFC motor is designed for continuous duty and is sealed against dust and other contaminants - a significant advantage in a woodshop.
This last type of table saw also appealing to the customer base on table saw reviews. It is maybe due to its features that are somewhat similar to those of the cabinet and contractor table saw. Just like the cabinet table saw, it also has a solid base with also lesser vibration and provides dust control. It is also compact just like the contractor saw but the thing is that it is much compressed than the first mentioned. However, this saw inclines to weigh less than a cabinet table saw but heftier than the contractor table saw. This makes it intended for most of woodworkers.
The rip fence guides the wood as it is being ripped (cut along its length) and can be positioned to any width of cut within the saw's range. The fence rides on fence rails attached to the front and rear edge of the table. Ideally, the system keeps the fence perfectly parallel to the plane of the blade, regardless of where the fence is positioned.
One drawback of lighter-weight table extensions is that they have less mass, and the overall mass of the saw is what soaks up the vibration crated by the motor and other moving parts. The added mass of heavy cast iron extension wings decreases vibration, which in turn helps the saw stay in calibration, and also helps it stay planted firmly on the shop floor. On less expensive saws, extensions made of stamped metal, or ones that aren't precision ground, can also compromise the overall flatness of the table surface.
At least one, but preferably two or more access doors should be provided leading into the cabinet of the table saw. The one you will use most often will be for cleaning out the interior of sawdust. Another should give easy access to the motor, trunnion and belts for adjustment and repair. Many saws provide a removable access panel instead of a second door. That's fine for occasional motor, arbor, belt and trunnion access but you will want the sawdust door to open and close easily.
