The electronics industry from time to time, many electronic products are more and more common, the demand is also increasing. The demand for accessories for electronic products is also increasing from time to time, for example: DC cooling fan, then what are the advantages of DC cooling fan worthy of merchants pro-gaze and sought after? Here Jiangshan to electronic simple to introduce the advantages of DC cooling fan.
1. The inverter has low cost and low inverter capacity. The current when the inverter continues to operate, the rated value refers to the peak value of the rectangular wave, the induction motor needs sine wave current, and the DC motor needs rectangular wave current. The current rating when the inverter continues to operate generally refers to the effective value of this sine wave. In order to maintain the ability of the inverter to control the motor current, there should be sufficient difference between the DC voltage of the inverter and the induced electromotive force of the motor. In this case, if the peak values of the current of the DC motor and the induction motor are assumed to be equal, the power output of the former is 33% higher than that of the latter, that is, the same rectifier/portal-saas/pg2024053116392597176/CMS/IMAGE/"style =" WIDTH: 600px; Height: 600px;" />
3. The loss is small and the efficiency is high. The loss caused by the excitation current of the induction motor is eliminated. At the same time, the permanent magnet DC motor works in a synchronous operation mode, due to the use of permanent magnet excitation. Eliminates the loss of the rotor of the induction motor. These two aspects make the operation efficiency of permanent magnet DC motor much higher than that of induction motor, and the efficiency of small capacity motor is more obvious.
4. Good speed performance and simple control. The speed control of DC fan is not only simple, but also has better speed control performance compared with the variable frequency speed control of induction motor.
These advantages and characteristics of DC cooling fan can be very good to make it applied to the electronic industry, mechanical equipment, because of its small and convenient and other reasons also make its application more common. In the future, with the rapid development of electronic products, cooling fans will certainly be able to gain more dominant positions and become an indispensable part of electronic products. Let's wait and see.
