Cooling Fan Manufacturer points

Date: 2015-3-6   Click: 1463 Times

(1) loss, high efficiency
Because "Cooling Fan Manufacturer" with 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) high power factor
Because reactive current "Cooling Fan Manufacturer" the exciting field does not need 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. With higher efficiency and power factor "Cooling Fan Manufacturer" and induction motor not only compared to the rated load, and at light loads more advantages.
