摘要： A fan for a ventilation system has a motor, a motor speed control unit and a controller arranged to control the motor to maintain the quantity of air flowing through the system constant. The controller compares the actual motor current with an expected motor current for the fan operating at the desired air quantity and motor speed to determine an actual system operating condition. When the difference between the actual motor current and the expected motor current is greater than a preset range, the motor speed is adjusted to a new motor speed determined based on the actual system operating condition. The system operating conditions may change due to changes in the static pressure of the system such as changes to the ventilation ducting or external wind pressure.
