A system for driving a blower of a heating, ventilating, and/or air conditioning (HVAC) system. The blower discharges heated or cooled air to a space for conditioning the air in the space by changing its temperature. A motor drives the blower at a speed or torque defined by a motor control signal thereby to control air flow rate of the HVAC system. The system includes a temperature sensor generating a temperature signal representative of the temperature of the air discharged to the space by the blower. In response to the temperature signal, a control circuit generates the motor control signal to cause the motor to operate at a minimum speed or torque until the temperature of the discharged air as represented by the temperature signal reaches a reference temperature. After the temperature of the discharged air reaches the reference temperature, the control circuit generates the motor control signal to control the motor speed or torque as a function of the difference between the temperature of the discharged air and the reference temperature whereby the air flow rate of the HVAC system is increased as the temperature difference increases.
