What Your Appliance Will Be Running On In The Future
In the modern era, domestic appliances are mostly driven by electric motors. Whether you are running hand mixers in the kitchen or a lawn mower out back, they are powered by a motor. And chances are these days that that motor is electric.
There are three types of electric motor. Universal brush motors have high torque and variable speed; you'll find them in drills and washing machines. Induction motors are silent, safe and reliable. They are found in refrigerators and pumps. New motors coming on the market, on the other hand, try to combine the best of both these worlds. These new motors are very exciting because they combine the high torque of brush motors with the silent durability of brushless.
Micro controllers have long been used for the interface functions of modern appliances. They are just now beginning to be used to control the motors themselves. The advantages in energy savings, silent operation and simplicity are becoming more and more important as technology advances and our ecological needs increase.
Variable speed is a must in high torque applications like drills, vacuum cleaners or even a Poulan chainsaw. By varying the speed, power efficiency can be increased by as much as 30 percent. The designers can also make the units smaller, lowering their price in the market.
Washing machines use a variable speed motor to lower the amount of water and electricity they use. Getting an induction motor to provide that variety lowers the efficiency because the controllers are too expensive. For this type of application, new magnet technology is the answer. They run at slower speeds, saving energy; they are also quieter and create less waste heat.
Permanent magnet motors are becoming increasingly attractive. They use less copper and steel in their construction, an important point in these resource poor times. The ups and downs of the commodities market will not have as much effect on the price of these motors. In fact, their growing popularity in applications ranging from automobiles to cellular phones has driven overall prices down.
We may not see these motors in every application; the Homelite chainsaw with a permanent magnet may not come around any time soon. But look for this innovative motor in appliances like washing machines and refrigerators. With the high torque of a traditional universal variable-speed motor and the quiet, dependable strength of the stator-driven induction motor, these workhorses are going to be an important part of our electric future.
