AC Fans are widely adopted in many industrial fields, playing an important role in cooling systems. Among them, UF12A23-BWHNR is a type of electronically commutated (EC) AC fan that helps to provide more efficient and reliable ventilation and cooling both in industrial and commercial applications. This article will focus on the application field and working principle of UF 12A23-BWHNR AC fan.

Application Field

In industrial fields, UF 12A23-BWHNR AC fan is mainly applied in factory automation systems, ventilation, air-conditioning, power supplies, and special device cooling. Its 230V AC input voltage rating and long distance travels make this fan suitable for various industrial equipment, especially for large scale applications. Being an energy efficient fan, it helps to save electricity, to contain space and to prevent the system from becoming overheated.

In commercial fields, UF 12A23-BWHNR AC fan has been increasingly used in consumer electronic devices such as refrigerators, air-conditioners, dehumidifiers, and TVs. Its high airflow and pressure provide excellent cooling when it is applied in these cooling systems. Its low noise and low vibration provide comfortable living environment and satisfactory customer experience.

Working Principle

The core of UF 12A23-BWHNR AC fan consists of a DC brushless motor and a permanent magnet rotor. The DC motor is driven by electricity to spin the permanent magnet rotor. The rotor is attached to the construction of fan blades to provide air circulation. To control the motor rotation, an external drive circuitry is applied on the brushless DC motor to convert the AC power into DC power and to power the motor rotation.

The drive circuitry consists of a power supply circuit, a rectifier circuit, an inverter circuit, and a commutator circuit. The electricity coming from the AC power source is rectified by the rectifier circuit into DC power. Since this DC power is not enough to drive the motor, it is further converted into higher voltage and current by the inverter circuit. The commutator circuit varied the current to maintain the smooth functioning of the motor. This current change causes the motor to rotate in the same direction as the rotor, which drives the fan blades and finally creates air circulation.

The drive circuitry is controlled by a motor controller, which is continuously monitoring the output of the AC power source to make sure a stable operation with high efficiency. The controller is designed with multiple temperature sensors and an adjustable speed control switch to allow the users to adjust the speed of air flow manually.

The UF 12A23-BWHNR AC fan is a highly reliable device due to the efficient working mechanism of its drive circuitry and motor controller. Furthermore, its ultra thin construction and high-quality engineering materials make it one of the most popular AC fans in the market.
