2, look at the motor material: the core component of the motor is the movement, there are many kinds of movement materials, the most commonly used materials on the market are: pure copper movement, copper-clad aluminum movement, aluminum wire movement. Pure copper core is magnetically conductive, with small attenuation coefficient, longest service life and most expensive cost; Followed by copper-clad aluminum, followed by aluminum motor.
3. Look at the capacitor configuration: As an important part of the electric fan, the capacitor can reflect the advantages and disadvantages of the motor from the side. The smaller the capacitance value of general household electric fans, the smaller the starting current of the motor, the more energy-saving and the more stable the performance of the motor. In addition, the greater the rated voltage, the stronger the capacitor's ability to resist voltage surge and the more stable the motor performance.
4. Look at the gear setting and operability: users should also pay attention to the gear setting of the electric fan when purchasing. Multi-gear can provide a variety of air volume and a variety of mode options. In terms of operability, many machines have remote control or can be connected to mobile phones for control, which can be controlled while lying in bed, which is relatively convenient.
5. Look at the way the electric fan shakes its head: the shaking of the electric fan determines its air supply range. Generally, electric fans shake their heads up and down, manually, pitching, left and right shaking, 360-degree shaking, O-shaped shaking and figure-eight shaking. The way of shaking your head can be selected according to your needs. If you use a wide range of people, you should give priority to the function of shaking your head left and right. If you need to adjust the air conditioning temperature and promote air circulation, you should choose to shake your head 360 degrees or O-shape.
