DC fans are electronically commutated motors with embedded electronics, which ensure energy-efficient operation and also enable intelligent control features such as speed control, temperature control, monitoring, alarms, etc. The 9S1212P4F011 is a highly reliable, 120x38mm DC fan designed for tight spaces and efficient cooling, making it ideal for a variety of applications.

Application Field

The 9S1212P4F011 is suitable for cooling in industrial, communication, computer, medical, and other fields which require cooling equipment or have special application requirements for noise, operating temperatures, and power-saving. It is well-suited for cooling in high data rate communication equipment, servers, telecommunications base stations, and information terminals, and its excellent cooling performance also makes it an ideal choice for cooling in industrial control equipment, medical and measuring equipment, driver systems, and broadcasting systems. It is also especially suitable for high-speed and low-noise operations in small spaces.

Working Principle

At the core of the 9S1212P4F011 is a brushless DC motor with 4 fixed electromagnetic poles, one commutator, and a rotor. When current is applied, the rotating magnetic field produced by the stator attracts the rotor and causes it to rotate. The commutator on the rotor works with the stator coils to ensure that the rotor is always in the same position with respect to the static magnetic field. As the stationary magnetic field rotates, it causes the rotor to spin, resulting in air flow. This gives the 9S1212P4F011 its excellent cooling performance.

The 9S1212P4F011 also includes intelligent built-in motor control electronics which can monitor and regulate the speed of the fan, as well as monitor the temperature around it. It also features automatic restart capability for protection against thermal overloads, short cycles, and other potential problems. This intelligent motor control also helps to reduce power consumption, making it an energy-efficient solution.

Overall, the 9S1212P4F011 is an excellent, reliable choice for a wide range of applications, from industrial control equipment to servers. With its built-in motor control and energy-efficient operation, it is an ideal cooling solution for those who need something that is both quiet and efficient.
