Recently, Dyson presented its new airwrap molder and dryer Co-Anda 2x. It is a hair care device that has 6 different accessories, doubles air pressure and allows it to dry, wave, smoothly cause heat damage. But The interesting thing is not your versatility, but technology behind.In particular the Hyperdymium 2 engine.
The first thing that stands out of “Heart” of the Airwrap Co-Anda 2x is its size: less than 28 mm, more or less as a 20 cents currencya cable that feeds it whose thickness is (ironies of the purpose of the device) that of human hair and can turn about 150,000 rpm, a speed almost 10 times higher than that of a formula 1 motor.
The increase in power is accompanied by a new aerodynamic system that includes a high -performance mixed flow driver and a over -overd bilayer diffuser. This generates a greater air flow and twice the pressure, without increasing the noise level.
One of the keys was the design. Instead of doing so based on previous models, the Hyperdymium 2 engine was developed from scratch. At the base is a more concentrated motor core and the use of neodymium magnets. This type of magnets, contrary to conventional ones, They are recognized for their exceptional resistance, allowing smaller, light and efficient designs. In addition, they have a good resistance to polishing, which means that they retain their magnetism over time and in variable conditions.
The other great advance is the use of ceramics on the engine axis, instead of resorting to habitual steel. Ceramics offers several advantages over steel, including greater wear resistance, greater hardness, better corrosion resistance and high temperatures, and lower electrical conductivity. In addition, some types of ceramic are lighter than steel. Thanks to this, higher speeds are achieved without losing durability.
Finally, we have the stator, basically the fixed part of a rotary machine, such as an engine. The stator usually contains the coils that create a magnetic field that interacts with the rotor to generate movement. Dyson has designed the fifth generation of its stators for the Airwrap Co-Anda 2x with trapezoidal copper windings that allow to store even more copper and more steel in less space.
All this makes A smaller engine can increase its power by 20% without generating more noise or wear in the pieces. To better understand the engine characteristics that Dyson has placed in a hair dryer (speaking in basic terms), we can imagine a particle accelerator such as LHC. Both these types of accelerators and the Airwrap Co-Anda 2x engine use magnetic fields.
The difference is that particle accelerators use magnetic fields to accelerate and direct loaded particles, while electric motors use them to convert electricity into mechanical energy.
Neodimium magnets in electric motors are essential to create a powerful magnetic field that interacts with electric currents to produce torque and rotational movement, thus boosting the engine. Hence the importance of A neodymium magnet, 10 times more powerful than ceramic in a similar size. Which means that its size can be reduced 10 times and maintain the power of a ceramic. And with more useful life.
