DC Fans

DC fans refer to fan products whose motors are equipped with DC motors. Due to the characteristics of DC motors, DC fans are relatively simple in terms of structure, have reliable performance, and are suitable for use in harsh environments. In addition, as it is an electrical product, a voltage regulator can also be configured to achieve the purpose of saving energy.

RER225-55/18/2TDMLO application field and working principle

The RER225-55/18/2TDMLO DC fan is widely used in many fields. It is a DC fan whose model number is RER225-55/18/2TDMLO. Its operating environment temperature range is 0-70 °C, and its output power is 45W. In addition, its noise is 50dB (A) and its air volume is 514CFM.

RER225-55/18/2TDMLO DC fan works by motor speed control. Its motor is an electronically commutated permanent magnet DC motor. The motor consists of a rotor and a stator. The rotor is a permanent magnet type, and its stator consists of an excitation winding and a detection winding. The excitation winding is composed of three parts, respectively connected to the three power terminals of the fan. The detection winding is connected to the speed controller. The speed of the fan is controlled by properly adjusting the excitation current of the excitation winding. The controller sends the current to the excitation winding on the stator so that the rotor obtains the torque generated by the interaction between the magnetic field of the stator and the permanent magnet on it; when the rotor rotates, air is drawn in from the back of the fan and blown out of the front section, thus creating a wind.

RER225-55/18/2TDMLO DC fan is ideal for a variety of applications such as HVAC, air conditioning, cooling system, medical equipment and many other industrial and commercial applications. It provides reliable performance and energy saving in harsh environments. In addition, due to its simple structure, it is easy to install and maintain.
