(1) "220V Cooling Fan" loss, high efficiency
Because the use of a permanent magnet excitation, eliminating the induction motor excitation currents losses; while permanent magnet brushless DC motor operates in synchronous operation mode, eliminating the rotating frequency induction motor rotor core loss. Both make operating efficiency permanent magnet brushless DC motor is much higher than induction motors, small-capacity motor efficiency improvement is more obvious.
(2) "220V Cooling Fan" high power factor
Because reactive current excitation field brushless DC motor does not require power, so the power factor is much higher than induction motors, brushless DC motors can be run on a power factor, which is extremely beneficial for small power motors. "220V Cooling Fan" brushless motor and induction motor with higher efficiency and power factor, not only when compared to the rated load, and at light loads more advantages.
