Flexible Ferrite Soft Magnetic Strips in Motor Cooling Fans

Motor cooling fans are an indispensable part of electronic devices, especially for high-power motors or devices that run for long periods of time. In order to improve the cooling efficiency and ensure the stable operation of the motor, soft magnetic strips are often used in cooling fans. These soft magnetic strips not only help the motor to dissipate heat more efficiently under high loads, but also enhance the magnetic suction of the fan, improve air flow, and ensure long-term stable operation of the motor. In this article, we will introduce in detail the composition, characteristics, applications and supply forms of soft magnetic strip materials used in motor cooling fans.

Main component of the soft magnetic strip in the motor cooling fan;

The percentage range of barium (strontium) ferrite magnetic powder is about 85%~92%. Barium (strontium) ferrite is a common permanent magnetic material with high magnetic properties and good corrosion resistance. This magnetic powder is the core component of soft magnetic strips, giving them their magnetic function.

The percentage range of CPE (chlorinated polyethylene) is about 5% to 9%. CPE is a polymer elastomer material with excellent flexibility and weather resistance. It acts as a binder and substrate to evenly distribute and fix the magnetic powder into shape, giving the soft magnetic strip a certain degree of flexibility and mechanical strength.

Shape and properties of flexible rubber magnetic strips

The shape is mainly multi-pole flat, this shape is especially suitable for use in motor cooling fans, some customers are magnetizing themselves. The main characteristic is good flexibility and malleability, can be easily bent or molded, easy to mass production and assembly.

In a cooling fan, the rubber ferrite magnetic strip interacts with the stator coil to drive the fan blades to rotate through the principle of electromagnetic induction, thus generating airflow for heat dissipation. Therefore, the magnetic strength, layout and material quality of the motor's magnetic strips are directly related to the fan's speed, torque and efficiency.

Rubber magnetic strips in the current market are usually supplied in rolls or cut into strips for easy processing according to customers' needs. Depending on different design requirements, the soft magnetic strips can be simply cut or adjusted to fit different specifications of fans.
