It depends on purchasing a purifierPurifier motor?This is the first reaction of many people when they read this article, and Ever Power's answer is: Regardless of the product structure, the impact of the motor on the purification effect is greater than imagined!

The working principle of the air purifier is actually not complicated.Simply put, it uses the rotation of the internal fan to generate airflow, and when the air passes through the filter, the pollutants are absorbed, thereby expelling clean air.In this process, the motor plays a very important role. Its performance directly determines the size of the wind, the purification effect, etc., and also affects the intuitive user experience of the machine's noise and vibration. It can be said that the motor is the core of the purifier. Parts.

①Working voltage

According to the different working voltages, motors can be divided into two categories: high-voltage motors and low-voltage motors. As with the previous "domestic VS imported" problem, we cannot generalize the evaluation of the two.High-voltage motors have the advantages of small current, large torque, more stable, energy-saving and high-efficiency. The speed is usually not very high, but compared with low-voltage motors, the cost is higher, and the manufacturing process and working environment requirements are higher.

②Input current

AC or DC?This is a big problem and one that has a greater impact on the performance of the motor.However, most air purifiers currently use DC motors. Although DC motors have disadvantages such as poor durability, their advantages are that they can directly adjust the voltage, and the startup curve is better than that of ac gear motors; and its speed adjustment is quite simple, only It is only necessary to add a resistor to adjust the voltage, which is one of the reasons why LIFAair LA500V can achieve "infinitely variable speed".

③External workmanship

The external workmanship mainly refers to the presence or absence of plastic packaging. During the disassembly, we also found that the motors of some products do not have plastic packaging and are directly "naked" on the outside. Compared with the plastic packaging motors, their performance in noise suppression may be slightly inferior. .
