ABSTRACT:
A method for suppressing current peaks occurring during commutation in phase windings of a brushless direct-current motor, including supplying the phase windings via an indirect direct-current converter with rectangular current having an actual value measured exclusively in a direct-current link of the converter (single-current measurement), and delaying current buildup in the phase winding by a time period t.sub.v with respect to a current decay.
