Focusing on developing high-performance and long-lasting cooling fans

The working principle of cooling fan

The working principle of cooling fan

Using the principle of electromagnetic induction, the fan uses the Houle induction module as a synchronous detection device, controls a set of circuits, switches the winding electrification sequence, and generates a rotating magnetic field, a mechatronics engineering fan for electronic commutation. The cooling fan has obvious advantages in the aspects of wide speed range, light weight, environmental protection and energy saving, controllability, reliability, environmental endurance and economy, etc. , dominate. The cooling fan is powered by direct current. The DC motor is composed of stator and rotor. The stator has a magnetic pole (winding type or permanent magnet type) , while the rotor has a winding, after the staff electrified it, the rotor also forms a magnetic field (magnetic pole) , there is an angle between the stator and the rotor magnetic pole, in the stator and rotor magnetic field (N-pole and S-pole) under the mutual attraction, is the motor rotation. The cooling fan technician told us to change the position of the brush, you can change the direction of the rotor-stator magnetic pole angle (starting with the stator's magnetic pole, the rotor's magnetic pole is on the other side, and the direction from the rotor's magnetic pole to the stator's magnetic pole is the direction of the motor's rotation) , after this operation, the rotation direction of the motor can be changed.

What is the difference between a DC fan and an AC fan?

The working principle of a DC cooling fan: It is driven by 4102 DC voltage and electromagnetic induction. 1653 converts electrical energy into machinery to drive the fan blades to rotate, relying on the coil and IC to continuously switch, and the induction magnetic ring drives the fan blades to rotate.
