More Information
Summary:The utility model relates to ventilating equipment, which comprises a fan blade and a motor, wherein the fan blade is arranged in a frame; the motor is a direct-current brushless motor; and a rotary shaft of the motor is directly connected with the center of the fan blade. The ventilating equipment adopts a driving mode of the rotary shaft of the motor being directly connected with the fan blade, so that the energy loss due to a transmission mode through a belt in the past is reduced, and the post maintenance work such as belt replacement is removed. The direct-current brushless motor (a direct-current brushless position sensorless motor and a direct-current brushless motor position sensor motor) can carry out stepless speed regulating through a motor controller, and a user can adjust the rotating speed of a fan according to the demand of actual air quantity. The ventilating equipment is energy saving and environmental-friendly.
