DC Fans

DC fan motor operations are based upon the relationship of voltage and torque. A DC motor\'s torque is proportional to the current passing through the motor, which is capable of producing a constant speed with varying loads. DC fans, also referred to as permanent magnet brush DC motors, typically operate off of 12-volt DC power sources.

The 8412NML is a very popular DC fan, designed to meet a variety of applications, such as HVAC, automotive, and industrial applications. The 8412NML is most commonly found in cooling systems as a part of the HVAC system or in vehicle cabins. These fans are designed to provide adequate cooling, with low power consumption and good reliability. In terms of design, the 8412NML is a 110 mm x 73 mm x 114 mm, brushless, permanent magnet DC fan.

The fan provides excellent performance in both static and dynamic pressure applications, along with low noise operation. It utilizes the stator\'s permanent magnet field as its power source, and the rotor is magnetized with copper rings. The rotor is typically made of aluminum to give it additional strength. The motor produces a torque of up to 1.25 N·m.

The 8412NML offers a wide range of features that make it an attractive option for cooling applications. It provides an operating temperature range between -25 °C and +70 °C, allowing the fan to operate in a wide variety of climates. The fan is equipped with dust protection, an anti-vibration system, and reverse polarity protection. These features make it a great choice in harsh and dusty environments.

The 8412NML has a high efficiency rating, with a peak operating efficiency of up to 50%. The fan is capable of operating at more than one speed, achieving speeds of up to 10,500 RPM. It has a starting voltage range of 5 to 10 volts and a starting current of 0.25A. By using a voltage regulator, the fan can be operated at voltages between 5 to 24 volts.

The 8412NML is designed to operate at low levels of noise and vibration. Its sound levels are rated at 40 dBA at a distance of 30 cm, and its vibration levels are below 0.20G. This makes it suitable for use in most noise-sensitive applications. Additionally, the fan offers low power consumption, drawing only 5.1W at full speed.

In summary, the 8412NML is designed for a wide range of applications. Its performance and features make it an attractive option for cooling systems. Its low power consumption, low noise levels, and dust protection make it suitable for use in harsh and dusty environments. It can be operated at multiple speeds, achieving speeds of up to 10,500 RPM. Additionally, its high efficiency rating makes it very energy efficient.
