DC Fans

OD5020-12MSS is a typical DC fan. It involves several technical characteristics, various applicable fields, and a unique working principle, which make it stand out in the industry. This article is intended to provide a clear overview of the features included in the OD5020-12MSS, its application field and working principle.

Technical Characteristics

The rear integrated fan module of OD5020-12MSS is special in its design. The fan comes with a usable air flow rate of 30.47 CFM, which is quite impressive considering its small size. It has an affordable maximum speed rating of 3900 rpm, which is lower than many of its competitors. However, the noise level of OD5020-12MSS is remarkably silent – merely 36.8 dB. This is very important as quieter operation is always preferred.

The OD5020-12MSS fan also has the starter power of 40 Watts and the input current of 0.41A. This fan uses a 12-volt voltage, which is not very common. This has the advantage of saving energy and money. Moreover, the OD5020-12MSS is equipped with two types of bearings, which are sleeve and ball bearings. The sleeve bearing is suitable for lower load applications, while a ball bearing is for higher loads. Both types of bearing feature a long life span of 50,000 hours.

Application Field

The application field for this fan type is quite broad. In fact, various industries use the OD5020-12MSS. These include the automotive, the consumer electronics, the health care, the mobility, the defence, the railway, and the renewable energy. In the automotive industry, this fan type is used for air conditioning, radiators, ventilation, cooling, and air filtration. In the consumer electronics, it is used for PC cases, handheld devices, and home appliances.

In the health care and mobility industry, the fan type is used for medical equipment and electrical wheelchairs, respectively. Also, in the defence industry, the OD5020-12MSS is used in military vehicles, tanks, AV systems, and Communication systems. The railway industry uses it for shunting station ventilation systems, while the renewable energy industry uses it in solar and wind energy installations.

Working Principle

The OD5020-12MSS fan works with a brushless motor. It is a four-pole motor with a permanent magnet rotor and a stator of coils, which exploits the Faraday principle of electromagnetism. This means that whenever a current is applied, a magnetic field is induced, resulting in a mechanical force. This force then causes the blades of the fan to rotate.

The fan\'s speed is regulated by Pulse Width Modulation (PWM), which is a varying control method. This involves varying the control signal’s pulse width in order to affect the fan\'s speed. This also allows the fan to maintain its desired speed, even under varying speeds and airflow parameters. This is made possible by the Electric Signal Control (ESC) board, which continuously monitors and adjusts the RPMs corresponding to the varying loads.

Conclusion

In conclusion, the OD5020-12MSS fan type has several desirable technical characteristics and is suitable for broad industry applications. It is equipped with two types of bearing – sleeve and ball bearings – and its working principle is based on the Faraday principle of electromagnetism. Moreover, its speed is regulated by the Pulse Width Modulation (PWM) and the control signal’s pulse width adjustment is done automatically by the present ESC board. All these features make this fan a worthy product for customers.
