Abstract

A method for controlling air volume output by a motor. The method includes: 1) establishing functional relation formulas for air volume in a low torque interval and a high torque interval; 2) inputting a target air volume into a microprocessor control unit; 3) starting a motor under a torque to enable the motor to reach a steady state; 4) acquiring an adjustment coefficient under the torque, and calculating the air volume; 5) comparing the target air volume with the calculated air volume; 6) re-recording a steady rotational speed after the motor reaches a new steady state under an increased or reduced torque, and recalculating the air volume in the new steady state; and 7) repeating steps 5) and 6) to adjust the torque until the calculated air volume is equal or equivalent to the target air volume.
