AC/DC power supply circuit + brushless DC motor unit for hair dryer

By replacing the general-purpose motor with a brushless DC motor, the hair dryer has been significantly reduced in size and weight.

Hair dryers with universal motors are large, heavy, and vibrate a lot

In the past, hair dryers used DC universal motors, which achieved high-speed operation with household single-phase AC power. However, in the field of home appliances, the trend of energy saving, small size and light weight is becoming stronger and stronger. In the field of hair dryer products, the demand for brushless DC motors, which Nidec excels in, is also gradually increasing.

Nidec supplies DC/DC power supply circuit + brushless DC motor unit to top hair dryer manufacturers, which reduces weight to less than half and size significantly compared to conventional DC motors. Due to the miniaturization and lightness, hair dryers are more convenient to use. For example, professional hairdressers have reported that this small and light hair dryer reduces their risk of tenosynovitis, an occupational disease.

Compared to general-purpose motors, this brushless DC motor + compact circuit is significantly smaller and lighter.

In the future, we will not only use motor + power circuit, but also make full use of advanced fan design technology.

Currently, we also provide power circuit + brushless DC motor unit. Nidec has advanced technology in the design of fans and blowers.
In particular, we have innovative technology in the core processes of fan and blower design, namely fluid analysis, thermal analysis, noise and vibration analysis. While making full use of the simulation calculation functions of supercomputers, we have carried out many unique blade designs in IT fields such as servers and PCs and home appliances such as refrigerators and electric fans, and have made great contributions to improving the performance of the products equipped.
In the future, we will continue to improve the accuracy of fan design and module design, reduce the speed while maintaining the same air volume as the current one, so as to reduce noise and vibration, and contribute to the realization of higher performance hair dryer products.

The performance of the hair dryer is improved by using a fan design that uses advanced fluid analysis technology.
