Brushless "Tiny Cooling Fan" uses a brushless motor drive, no electromagnetic interference, completely overcome brush-commutated motor electromagnetic interference, noise, short mechanical life drawback is widely used in electronics and electric heat applications should be compulsory. Brushless "Tiny Cooling Fan" because there is no brush, no maintenance, long life, high precision speed regulation. Therefore, brushless DC fan is rapidly replacing the traditional brush motor, household appliances with inverter technology (such as inverter air conditioner, inverter refrigerator, etc.) is the use of brushless "Tiny Cooling Fan", almost all of the current DC fan-free brush motor.
