Working principle of Brushless DC fan driver
Brushless motor uses winding as stator and permanent magnet as rotor. The brushless motor uses electronic circuit to switch the power on sequence of windings to generate rotating magnetic field and push the rotor to rotate.
Brushless motor has no carbon brush, no maintenance, long service life and high speed adjustment accuracy. Therefore, brushless motor is rapidly replacing the traditional brush motor. Household appliances with frequency conversion technology (such as frequency conversion air conditioner, frequency conversion refrigerator, etc.) use brushless motor. At present, almost all of the cooling fans use brushless motor.
