DC Fans

DC fans are widely used in electronics and automotive applications as part of cooling and power management systems. Motor operation usually requires two wires for the positive and negative sides of the DC power supply, while the third wire serves as the tachometer for measuring fan speed. The 109E5724K501 fan is a DC fan designed for high performance applications in these types of systems.

Application Field

The 109E5724K501 is a 24VDC fan designed for high performance cooling systems and industrial power management systems. It is suitable for applications such as telecommunications, heating and air conditioning, and automotive electronics. It also has a wide range of temperature tolerance, from -30 to +125 degrees Celsius, meaning it works efficiently even in harsh environments. Furthermore, it is an UL recognized component and carries an RoHS certification.

Working Principle

The 109E5724K501 has a brushless DC motor at its heart. This motor contains a stator, which is made up of a series of static magnets, and a rotor, which is made up of an electromagnet. When the rotor is energized, the stator and rotor magnets interact, creating a strong magnetic force that forces the rotor to rotate. This force is constantly changing, creating a cyclic motion as the stator and rotor change polarity. The rotation of the motor is what powers the fan, allowing it to move air over the heat sinks, thus cooling the system.The 109E70024K501 also incorporates a tachometer for monitoring speed and controlling the airflow. This is an important feature as the speed of the motor determines the intensity of the airflow. The tachometer is connected to the motor through a hall effect device, which measures the magnetic field created by the rotation of the motor. The tachometer then sends this data to a motor controller, which can make necessary adjustments to ensure the desired airflow is achieved.

Conclusion

The 109E5724K501 is a reliable and powerful DC fan designed for high performance applications in cooling and power management systems. It incorporates a brushless DC motor and tachometer for accurate speed and airflow control, and is durable enough to withstand extreme temperatures. It is also certified by UL and RoHS for safety and reliability. As such, the 109E5724K501 is a great choice for any industry or application that requires high performance cooling.
