Smart Control of Brushed DC Motors Improves Efficiency (.PDF Download)
Motors are everywhere, more than you think. If you doubt this, just try counting all of the motors in your home, car, and office that you use every day. The large motors are obvious, but it’s the small ones buried in some other object that you tend to forget. These motors are hidden and not recognizable as such, and many if not most are battery-operated.
Lots of these small motors are now showing up in office buildings, factories, and other facilities. Some home examples are the motors in smart door locks, video doorbells, video-surveillance cameras, and smart utility meters. One of the most widespread applications involves smart sanitation products, such as automatic paper-towel dispensers, faucets, soap dispensers, and smart toilets.
