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

Create Date: 2024-8-30 12:03:23|Source: Nidec

The general-purpose motor has been replaced with a brushless DC motor, which greatly reduces the size and weight of hair dryers.

NEEDS further miniaturizes and lightens hair dryers

SOLUTION Significantly reduces weight by miniaturizing brushless DC motors + circuits

Hair dryers equipped with general-purpose motors are bulky, heavy, and vibrate

In the past, hair dryers used AC general-purpose motors, and they used single-phase alternating current for household use to achieve high-speed operation. In the field of home appliances, the trend towards energy saving, miniaturization and weight reduction is increasing, and in the field of hair dryer products, the demand for brushless DC motors, which Japan Denco specializes in, is also increasing.

Japan Electronics Co., Ltd. supplies AC/DC power supply circuits + brushless DC motor units to top hair dryer manufacturers, reducing the weight by less than half and significantly reducing the size of conventional AC motors. The miniaturization and lightweight reduction of hair dryers has made it easier to use, for example, professional hairdressers have reported that this small and lightweight hair dryer reduces their risk of developing tenosynovitis, an occupational disease.

Compared to general-purpose motors, it is a much smaller and lighter brushless DC motor + compact circuit.

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

Currently, we also provide power supply circuits + brushless DC motor units, and Japan Denco has advanced technology in the design of fans and fans.

In particular, we have innovative technologies in the core processes of fan and blower design, namely fluid analysis, thermal analysis, noise and vibration analysis. In addition to making full use of the simulation and calculation functions of supercomputers, we have made a number of unique blade designs in IT fields such as servers and PCs, as well as in home appliances such as refrigerators and fans, and have made significant contributions to improving the performance of the products installed.

In the future, we will continue to improve the accuracy of fan design and module design, reduce the rotational speed while maintaining the same airflow as we currently do, and reduce noise and vibration, contributing to the realization of higher-performance hair dryer products.
