METHODS AND SYSTEMS FOR OPERATING DIRECT CURRENT MOTORS 5OF THE DISCLOSURE A method for applying power to an electronically commutated motor (ECM) is described. The method includes connecting an AC voltage source to an input of a 10 rectification circuit, connecting a DC voltage source to an output of the rectification circuit, and electrically connecting the DC voltage source and rectification circuit output to operational components of the ECM. The DC voltage source is capable of providing a voltage equal to 15 or greater than a rectified voltage originating from the AC voltage source, and the DC voltage source is connected in parallel with the output of the rectification circuit.
