(4) Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.This blower can be widely used onto vacuum machine,dust collector,floor treatment machine.Q: Can we connect this centrifugal air blower directly onto power source? A: This blower fan is with BLDC motor inside and it needs a controller board to run. Q: What kind of power source shall we use to drive this blower fan? A: Generally, our customers use 24vdc switching power supply or Li-on battery. Q: Do you also sell controller board for this blower fan? A: Yes, we can supply adapted controller board for this blower fan.Brushless motors fulfill many functions originally performed by brushed DC motors, but cost and control complexity prevents brushless motors from replacing brushed motors completely in the lowest-cost areas. Nevertheless, brushless motors have come to dominate many applications, particularly devices such as computer hard drives and CD/DVD players. Small cooling fans in electronic equipment are powered exclusively by brushless motors. They can be found in cordless power tools where the increased efficiency of the motor leads to longer periods of use before the battery needs to be charged. Low speed, low power brushless motors are used in direct-drive turntables for gramophone records.
