insight Induction vs. Universal Motors in Your electric Power Tools

As a woodworker you've likely not given much notion about the two former types of motors used to power your galvanic woodworking tools. The differences in operation - and the estimate of zeros on a price tag - should have your attention.

As in all considerations about power tools your extreme decision should be based on your projected Usage. If you're a newbie just getting started then it might not be time to spend in the cast iron induction-powered table saw.

If you're running a expert shop then all six of your table saws probably have induction motors.

Your duty to yourself as a buyer is to make educated decisions. In that interest here are some of the differences in the middle of induction and universal motors... Without getting too technical and without taking a "one motor is great in all situations" stance.

1) Size and Weight

Induction motors are typically heavier than universal motors, production them ideal candidates for stationary tools that need the extra weight anyways to cut rattling and enhance stability.

Obviously at their weight and size they make poor candidates for handheld or movable tools.

That's where universal motors come in to play. Their smaller size and weight make them ideal for circular saws, bench top planers and your shop vacuum.

2) Cost

Induction motors are more high-priced and found often these days in the top of the line galvanic power tools. They're made with more copper, aluminum and steel than universal motors.

Universal motors are less high-priced and found in just bout every galvanic power tool known to man.

3) Speed

Induction motors typically have a slower max speed.

Universal motors are only minute by friction.

4) Torque at Start Up

Induction motors have less torque at start up - think of them as "high gear" on your car or bicycle. Once they're at cruising speed they're good to go, but typically don't much like to be stopped and started frequently.

Universal motors typically have great torque at start up that get blades chewing straight through tough spots. They can cruise too but that leads us to...

5) Longevity

Induction motors are long-lived. There are stories of woodworkers using induction motor powered tools passed on by their grandfathers.

Universal motors are more likely to burn out in a shorter period of time. There are stories of universal motors persisting for 20 years and more, but as a very general rule universal motors don't last as long as induction motors.

6) Noise

Induction motors are quieter - far far far quieter - than universal motors.

Universal motors are widely known for their shriek and many residential areas have bans on their usage after a inevitable time of day.

(Note: you should wear hearing protection while using whether one...)

7) Standardization

Induction motors have been standardized by Nema. This means that it's easy to replace induction motors in your machines with appropriate motors from different manufacturers due to appropriate frames, shaft sizes, mounting dimensions and more.

Universal motors are typically characterized by their Lack of standardization, which can sometimes makes replacement difficult.

8) vigor Efficiency

Induction motors are extremely sufficient motors that wish less amperage per horse power.

Universal motors wish more amperage per horse power than induction motors. All this extra vigor requirement turns into heat in the motor which will sometimes burn them out - precisely - if used for extended periods of time.

9) Application: Your Final Decider

Ultimately whether you buy a tool where there's precisely a selection in the middle of induction and universal (table saws and planers for example) you will have to ask yourself how often you'll be using the tool and your likelihood of persisting with your hobby.

Your induction motor tools will have a higher resale value if you bail out of woodworking, but will cost you more in the upfront. Your universal motor power tools will have less of a resale value but cost less upfront.

If you walk into your hardware store with a basic understanding of the two major types of galvanic motors along with a firm idea of what your woodworking projects will be for the next few years you're going to walk away with the right tool for you. And that's the most any woodworker can ask for.
