DIY Home Improvement: Powering Up with BLDC Motors

DIY HOME IMPROVEMENT POWERING UP WITH BLDC MOTORS Thanks to the evolution of brushless DC motor technology, do-it-yourselfers have been able to keep improving their homes, garages, and yards with more efficient and durable power tools. AMERICANS TACKLE HOME IMPROVEMENT Brushless DC motors star in many home improvement projects, as they are often found in cordless power tools. Let's take a look at how homeowners put all those brushless rotations to good use. 53% Which Home Improvement Projects Are the Most Popular? of U.S. adults made a home improvement in the last year. 16% Bathroom remodeling 56% 7% Kitchen remodeling Bathroom of those who Remodeling & home additions completed home improvements spent $1,000 or more. 7% 6% Floor coverings New homeowners Kitchen spent $19 billion on home improvement projects last year. 5% Painting & wall covering What Improvement Projects Are Homeowners Planning for the Future? 22% 14% 12% 12% Garden or landscaping Bathroom Kitchen Family/living room THE POWER TOOL INDUSTRY & HOW AMERICANS USE POWER TOOLS BLDC motors power American's love for home improvement. Below, we explore how power tools are produced and used in the U.S. The American power tool market earned $3 billion in revenue in 2012, and employed 10,167 Americans. There are about 150 power tool companies operating in the U.S. today. 2012 $3 billion n employedii 10,167ii 150 POWER TOOL COMPANIES Drills are the most popular power tools; Demand for power tools is predicted to reach $7.3 billion by 2016. Cordless power tools will see the strongest growth, at 8.3% per year. 24% of all electric tools sold are drills. $4 $ $7.3 BILLION 24% $SSS$$$$$s$eSsS BRUSHLESS DC MOTORS: HISTORY & PERFORMANCE Power tool aficionados swear by home improvement gadgets with BLDC motors. Here we explore the benefits and history of brushless DC motors. How Brushless DC Motors Drive Power Tool Performance Evolution of Brushless DC Motor Technology Compared to traditional brushed motors, BLDC motors offer several benefits for power tool users: 1856 German inventor Longer motor life. No rotating brushes means less wear and tear. and industrialist Ernst Werner von Siemens builds the first 1880 brush DC motor. Von Siemens creates the world's first electric elevator. More powerful, since there's more space for copper windings, and less energy is wasted to friction. 1891 The Ward Leonard Drive System adds motor speed control to brushed DC motors. 1956 Longer run time. Brushless DC motors The first motor controllers operate more efficiently on the same charge. using thyristor devices are sold by the Electronic 1962 T.G. Wilson and P.H. Trickey unveil the first brushless DC Regulator Company. These solid state motor, which they called "a DC Smaller than power tools with brushed motors. machine with solid controllers can state commutation." more directly convert AC power to DC power. They soon supplant the Ward 1980s Smarter, since BLDC motors can Increased availability of permanent magnet materials. Along with high voltage transistors, these permanent magnets allow brushless DC sense and adjust to resistance in Leonard approach. material at hand. motors to generate as much or more power than brush DC motors. sinotech www.Sinotech.com Sources: Scarborough.com, Bankrate.com, Finance.yahoo.com, Thestreet.com, Ibisworld.com, Leaguepark.com, Popularmechanics.com, Wikipedia.org Copyright © 2014 Sinotech Infographic designed by Mad Fish SEO
