    摘要: A bathroom ventilator fan with the soft-start function includes an impeller and a motor. The motor is coupled to the impeller for driving the impeller to rotate. The motor has a control module for driving and controlling the rotation speed of the motor according to a soft-start signal. The soft-start signal includes a soft-start section and a target-driving section. The control module slowly increases the rotation speed of the motor from the soft-start section to reach the target-driving section.
