This type of high-power fans are generally powered by high-power lithium batteries. If you want to switch to a regulated switching power supply, you should pay attention to the current of the power supply must be large enough. The starting current of the fan must exceed 30A. And one more thing, the motor's wiring must identify the positive and negative poles. The terminal with the red dot is connected to the positive pole, and the other terminal is connected to the negative pole. If the connections are reversed, the suction power of the fan will become smaller and the noise will become louder.
The 545 motor is a brushed motor, and the voltage can be higher or lower, and its power is directly determined by the voltage. If this fan is used with DC9V, the current reaches 10.9A and the power is close to 100W. , but since these are motors with high power density, the voltage cannot exceed too much.
This type of fan is generally powered by high-power lithium current. It is best not to use a regulated switching power supply because its starting current exceeds 30A. Moreover, the fan needs to identify the direction of rotation due to the impeller, so please note that the terminal with the red dot is connected to the positive pole, and the terminal without the red dot is connected to the negative pole.
