(1) energy saving, compare ac electric fan, d c one can save power by 50% to 70%,
(2) the low temperature, due to the efficiency is greatly increased, the motor temperature rise is generally less than 50 k,
(3) high safety coefficient, power supply voltage is 12 v only, is far less than 36 v voltage human safety standards. In some countries can avoid doing safety standard certification.
(4) low noise, brushless motor for noise value is 50% of AC motors
