What are the characteristics and types of centrifugal fans?
As its name implies, centrifugal fans inhale the air along the axial direction, but blown out radially based on the centrifugal force of impeller rotation.01/24/2024 -
How to connect multiple fans to a single PWM interface?
As we all know, the PWM interface can adjust the fan speed, then can multiple fans be connected in parallel to one PWM interface?03/01/2024 -
What are the characteristics and types of axial fans?
Axial fans are usually installed on the cabinet of electrical equipment, and sometimes integrated on the motor. They are widely used for their compact structure which can save a lot of space and is easy installation.01/24/2024 -
How to connect the three-phase AC fan star delta?
Taking this R4D500-RA03-01 as an example, you can see that there are a total of 9 outlet wires of the fan. In addition to the two ground wires for thermal overload protection the white and the yellow-green one, the remaining 6 wires are the lead wires of the three-phase winding of the motor ( U1, U2, V1, V2, W1, W2) For wiring, we can refer to the wiring diagram in the fan or specification book. They are all clearly drawn, such as the wiring diagram in the specification book of this fan.02/29/2024 -
How to Select a Fan or Blower？
First of all, we need to clarify the purpose of the fan. Is the fan used for air ventilation, air purification, heat dissipation or other specific applications? Different uses require different types and specifications of fans.02/02/2024 -
Will extending leads affect the performance of the cooling fan?
extending the lead will not significantly affect the normal function of the fan, but it is different for high-power fans. When the lead is lengthened, the resistance will increase, which may lead to a reduction in voltage, thereby reducing the actual operating voltage, reducing the fan speed and air volume to affect the performance of the fan, especially for some applications that require fans to work at a specific speed or maintain a specific temperature, the impact will be even greater.03/01/2024
