Abstract
A method for applying braking to an electronically commutated motor that includes a switching circuit electrically coupled to one or more windings is described. The method comprises operating the switching circuit to remove power from the windings of the electronically commutated motor, determining when the rotation of a rotor of the electronically commutated motor has decreased to a predetermined speed, and operating the switching circuit to interconnect the windings of the electronically commutated motor such that currents passing through the windings are dissipated through components of the switching circuit and the windings.
