As a woodworker you've likely not given much thought regarding the two main types of motors used to power electric tools woodworking. The differences in performance - and the number of zeros on a price tag - should have their attention.

As in all considerations on power tools final decision should be based on its intended use. If you're a novice just starting, then it may be time to invest in the induction of iron cast table saw motor. If yours is a professional shop, all six of the table saws probably have induction motors.

Your duty of self as a consumer choices. In that interest here are some of the differences between induction and universal motors ... without being too technical and without a "a engine is better in all situations "stance.

1) Size and weight
Induction motors are typically heavier than universal motors, making them ideal candidates for stationary tools needed anyway the extra weight to reduce noise and improve stability. Obviously, their weight and size that make good candidates upper bank and shop vacuum.

Cost 2)
Induction motors are more expensive and often found these days on the top of the line of power tools. They are made with more copper, aluminum and steel universal motors. Universal motors are less expensive and is in fair combat all power tools known to man.

3) Speed
Induction motors typically have a slower max. Universal motors are limited by friction.

4) Torque at Start Up
Induction motors have less torque up - think of them as "high-train" in your car or bicycle. Once they are at full speed is good to go, but usually not enough to be stopped and started frequently. Universal motors often have a high torque at start-up until they chew through leaves of difficult situations. You can take a cruise, but also leads us to ...

Longevity 5)
Induction motors are long lasting. There are stories of woodworkers using induction motor tools powered past for his grandparents. Universal motors are more prone to burn in a shorter period of time. There are stories of universal motors lasting 20 years and over, but as a very general rule, universal motors do not last as long as induction motors.

6) Noise
Induction motors are quieter - until now much quieter - Than universal motors. Universal motors are widely known for his cry residential areas and many have the ban on its use after a certain time of day. (Note: you must wear ear protection while using either ...)

7) Standardization
Induction motors have been standardized by NEMA. This means it is easy to replace the induction motors on their machines with standard motors from different manufacturers, due to standard frames, shaft sizes, mounting dimensions and more. Universal motors are characterized by a lack of standardization, which can sometimes makes replacement difficult.

Energy Efficiency
Induction motors are highly efficient motors that require less amperage per horse power. Universal motors require more prolonged periods of time.

9) Application: Your Final Decider
Ultimately if you buy a tool that is really a choice between induction and universal (table saws and brushes, for example) will have to ask how often you use the tool and its likelihood to continue with their hobby.

The tools of his induction motor will have a higher resale value if you get out of the woodwork, but will cost more in advance. Its engine universal power tools will have less of a resale value but cost less in advance.

If you walk into your hardware store with a basic knowledge of the two main types of electric motors along with a firm idea of what their projects will work with wood for the coming years is going to walk with right tool for you. And that's the most any woodworker can ask for.
