Abstract
A method of determining torque of an electronically commutated motor arranged to drive a blower means for flowing air through a contained space with the electronically controlled motor and the blower means having a combined predetermined inertia. In practicing this method, power is applied to the electronically commutated motor, and the blower means is thereby accelerated to a predetermined speed. The power is then removed from the electronically commutated motor, and thereby the blower means is decelerated. The deceleration of the blower means is measured, and the torque of the electronically commutated motor is computed from the measured deceleration. A method of establishing a preferred rate of air flow and apparatus are also disclosed.
