You understand. DC brushless fan Huh? Do you know the basics of DC brushless fans? Let’s find out together with the editor!
Fan specifications: First, the fan size—referring primarily to the dimensions of the fan itself, typically expressed as the outer length and product thickness, with units in millimeters (mm). Fan model names often use these dimensions as part numbers; for example, in DC8025, "8025" indicates the specific size of the product.
Second is the rated voltage: this is the voltage value at which the fan is designed to operate under its rated conditions; commonly seen. DC fan The voltages generally come in specifications such as 5V, 12V, 24V, and 48V.
Third is the fan speed: the rate at which the fan rotates, measured in rpm (revolutions per minute). This is a relatively important parameter for fans. A higher rotational speed indicates greater airflow. Manufacturers often standardize their products into different speed categories—ultra-high (U), high (H), medium (M), and low (L)—to allow users to select the appropriate model based on their specific needs.
Fourth is airflow: a quantitative metric used to measure a fan’s capacity, with the unit being cubic feet per minute (CFM).
Fifth is wind pressure: the ability of the Peugeot ventilation flow to overcome air resistance. This indicator directly affects the efficiency of ventilation, air exchange, or heat dissipation, and its unit is mm-H2O.
Sixth is the noise level—a crucial parameter. Although it’s unrelated to ventilation and cooling performance, it places high demands depending on the specific environment. The unit is dBA (decibels).
Other configurations: Bearing system: This component is the heart of the fan and directly affects the mechanical lifespan of the product. Bearings are commonly categorized into ball bearings and oil-lubricated bearings. Connectors: These are relatively important yet often overlooked details on a fan. They typically come in various types, including non-ended, 2P, 3P, and large 4P connectors.

Advantages and Applications of Oil-Bearing DC Fans

The pivot joint is fixed at the position of the motor stator base, ensuring an appropriate gap between the rotor and the stator. Of course, there must also be a clearance between the shaft core and the bearings to prevent the shaft core from becoming locked and thus unable to function. The stator structure of the motor—hereafter referred to as the "stator"—is designed in such a way that, once power is supplied, an induced magnetic field will be generated between the rotor and the stator. The control circuit then drives the electric fan motor into operation. Therefore, in the conventional fan motor design, as long as the fan rotor, the motor stator, and the drive circuit work together via the pivot joint between the shaft core and the bearings and through magnetic field induction, the motor can operate effectively.
