Using Permanent Magnet Motors In Variable Speed Appliances
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 commercially available electric motors. The most common is the Universal, or Brush, motor. With high torque and variable speed, they work well for vacuum cleaners or drills. Induction motors have no brushes and run silently. They are single-speed and very durable and are used in pumps or refrigerators; anywhere you need constant pressure. The new motors on the market have all of these qualities: they operate at variable speeds, have high torque and they are silent and reliable.
Microcontrollers have been a part of the modern appliance for years, usually making their appearance in the switches and knobs that make them work. Now these tiny controllers are making their way inside the appliance, as well, controlling the current in an induction motor. Variation in current allows the motor to operate at different speeds.
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.
For washing machines, an induction motor won’t work very well because the controllers are too expensive. But new magnet technology is offering alternatives such as the permanent-magnet synchronous motor with sensorless controls and semiconductor technology. These new motors run at lower speeds and save energy. They run at cooler temperatures and are very quiet, creating less waste heat and noise that needs to be abated.
In fact, these permanent magnet motors are getting more and more popular. Because they use less raw material, such as copper and steel, their price points are less affected by the swings of the commodities market. And as their popularity grows, the overall prices of the magnets comes down, as well. Even now they are used in everything from cars to cell phones.
Of course, these wonders won’t work in every appliance. You won’t find one in your Homelite chainsaw any time soon, for example. But you will start seeing them more and more in refrigerators, drills, washing machines, pumps. With the high torque of traditional motors combined with the silent dependability of an induction motor, we have a perfect match.
