The phase windings are connected to each other, in particular the particular second phase winding terminals are connected to a shared star point, and phase-width-modulated voltage signals being applied separately to each individual phase winding, and at least one selected phase winding being at least temporarily connected to a constant electrical potential. To minimize switching operations and to reduce the alternating current component of the current source, the pulses of the pulse-width-modulated signals applied to the remaining phase windings are at least temporarily phase-shifted with respect to each other during the period in which the selected phase winding is connected to a constant electrical potential."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for operating and apparatus for activating a rotating, brushless electrical machine","description":"A method for operating a brushless, rotating electrical machine, including at least three phase windings, each of which has a first phase winding terminal and a second phase winding terminal.
