A control factor is determined periodically for each phase winding. The time periods during which an upper and lower supply voltage is applied to the phase winding are determined based on the control factor. The electronically commutated synchronous machine is actuated according to space vector modulation. Zero vectors are applied to the phase windings at the beginning and/or end of a period for a switch-off duration. All switches connected to the upper supply voltage or all switches connected to the lower supply voltage are on. The selection of the zero vector is performed in accordance with the phase winding with the greatest, in magnitude, deviation from the average control factor. As disclosed is an actuation circuit and the use thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for actuating a brushless motor","description":"A method for operating an electronically commutated synchronous machine, having a stator with at least two, in particular three, phase windings and a rotor having at least one permanent magnet.
