1. "220V Cooling Fan" speed performance, simple control: Compared with frequency control induction motor speed control brushless DC motor is not only simple, but also has better speed performance.
  2. "220V Cooling Fan" high power factor: Due to the reactive current excitation magnetic brushless DC motor does not need the grid, so the power factor is much higher than induction motors, brushless DC motors can operate in a power factor, which small power motor is extremely beneficial. Brushless motor and induction motor with higher efficiency and power factor only when compared to the rated load, and at light loads more advantages.
  . 3) "220V Cooling Fan" loss, high efficiency: Because the use of a permanent magnet excitation, eliminating the induction motor excitation current generated losses; and permanent magnet brushless DC motor is operating in synchronous operation mode, eliminating the induction motor rotor core The turn-frequency loss. So that the efficiency of both permanent magnet brushless DC motor is much higher than induction motors, small-capacity motor efficiency were much higher.
