AC Fans

OA938AP-11/22-1WB AC Fans is an industrial fan used for cooling. The fan motor, fan blade and fan casing are made of various structural materials. According to the power supply, the AC fan can be divided into AC and DC fans.

The OA938AP-11/22-1WB AC Fans has the characteristics of low noise and no vibration, and can work stably for a long time under any working conditions. It is widely used in air-conditioning units on the premise of ensuring air volume and static pressure. It is also widely used in cooling radiators and engine compartments.

The working principle of AC fan is related to the motor inside. The fan blades of the AC fan are driven by the motor to rotate in the windward direction at a high speed, and the air is continuously sucked in from one radial side to the other radial side, forming a suction and pressure cycle or suction and exhaust cycle.

AC Fans, like all AC motors, rely on alternating current to induce the rotation of the motor rotor. On the other hand, its circular magnetic field is generated by a rotating windings on the stator, which is connected to three leads (u, v, w) of an AC power source.

The applied voltage waveforms of the OA938AP-11/22-1WB AC Fans are rectangular pulses with an amplitude of 380 volts and a frequency of 50 Hz. This kind of waveform will cause a corresponding magnetic field in the stator winding, which interacts with the magnetic field in the air gap to produce a rotating torque to drive the rotor to rotate. When switching on, the relative position of the stator magnetic field and the rotor magnetic field changes rapidly, so the instantaneous starting torque is very large. In the process of operation, the motor speed is determined by the number of stator winding turns, and the magnitude of the electromagnetic torque is determined by the exciting current.

OA938AP-11/22-1WB AC Fans are mainly used in industrial applications. Such as fans, air conditioners, blowers, pumps and other equipment. In the air conditioners, blowers, fans and other equipment, the AC fan is used to control the fan\'s speed and reduce the noise. The AC fan can also be used in high temperature environment. Its wind pressure can be changed by adjusting the speed of the fan, so that the temperature can be effectively controlled.

With light weight and small volume, OA938AP-11/22-1WB AC Fans has remarkable energy saving characteristics, and has a long service life at the same time. Its structure is simple, convenient to maintain and easy to install. And its price is relatively cheap, so it is widely used in industrial applications.
