Abstract
A method for operating an electronically commutated synchronous machine with several phases, wherein an actuation circuit operates the synchronous machine, the actuation circuit having at least two switches for each phase and a degree of actuation for each phase being periodically ascertained by the actuation circuit, wherein the switch-on period, during which a supply voltage is applied to the respective phase by way of the associated switch, is determined for ascertaining the degree of actuation, wherein the following steps are carried out: measuring current by a single measurement resistor in at least two measurement windows and shifting one or more of the switch-on periods of the different phases relative to one another as soon as the difference between switch-on instants of at least two phases falls below a minimum period or the difference between the switch-on periods of at least two phases falls below twice the minimum period.
