I will give you a superficial introduction to the mainstream motor models of hair dryer motors on the market and the development history of motors. Today, Lao Zhang hopes to analyze with you from a deeper perspective why the history of motor development is these motors, not other motors? It also provides you with another aspect to understand, the law of the civilian development of motors.
【Product Requirements for Hair Dryers】
From the perspective of historical materialism, when we think about why series motors, brushed DC motors, and brushless DC motors have become the mainstream of hair dryer motors in the current market, we not only need to start from the current technical background of motors, but also It is necessary to consider the essential demand for the motor of the hair dryer.
When the technology and development of DC motors are still in a relatively low era, the shortcomings of DC motors seem to be very unfriendly to hair dryer products. Then let's take a look at the characteristics of the series motor, and you will understand why the series motor will become the enlightenment motor for the civilianization of hair dryer products.
l It can be used under AC power, and it is very convenient to use the power supply. First of all, designing a DC power supply for the hair dryer is itself a problem that needs to be solved. If the hair dryer can be directly connected to AC, then for the hair dryer, the usage scenario is very suitable, and the cost conversion rate is very high.
l The speed of the series motor is particularly high, and due to the principle of its own motor, the higher the speed, the smaller the amount of ferromagnetic material itself. The effect is that it is lighter, smaller and cheaper.
Seeing this, you should be able to understand why the hair dryer used a series motor at the beginning. Later, with the continuous improvement of the technology and research and development of DC motors by private enterprises, the production process and supply chain of DC motors became more and more mature. At the same time, with the development of the economy, the income of the middle class continues to increase. A rising tide means that,
The cost of DC motors can enter the ranks of daily consumer goods.
Let's take a look at the characteristics of DC motors:
l Compared with AC motors, DC motors are more energy efficient;
l The speed regulation performance of the DC motor is very good, the speed regulation range is very wide, and it is very smooth.
l The noise is much better than that of the series motor;
Although, the cost of DC motors will be much more expensive than series motors. However, with the needs of the market, the improvement of the product power of the DC motor is unmatched by the series motor. This is the core reason why DC motors are gradually replacing series AC motors.
【Upgrade of demand for hair dryer products】
In the same way, referring to Lao Zhang's previous article, it is actually very easy to understand why the trend of hair dryer motors changed from brushed motors to brushless motors, and then from brushless motors to high-speed brushless motors. In fact, the reason behind it is, on the one hand, the cost of the motor, and consumers are more able to pay for it. At the same time, the space for product design brought by the motor is also increasing. Students who make products can understand,
The reason why consumer goods are consumer goods is not only that consumers can afford them, but also that the user experience is getting better and better.
In fact, the needs of the motor, after a series of push downs, are reversed from the needs of users. Here, as a motor engineer, a universal motor solution is of course the ultimate dream of all engineers. However, only engineers who understand the needs from the perspective of consumers can design the best products.
