摘要：The invention relates to a circuit arrangement and a method for operation of anelectric motor in a DC supply network, in particular for the operation of a DC motor witha permanent magnet magnetisation in the DC network on a motor vehicle, whichcomprises a rotational position sensor (32), for recording the rotational position of therotor (20) and an electronic commutation controller (30), for switching the current in thearmature winding of the stator (12), depending on the position of the rotor (20).

According to the invention, the rotational position sensor (32) is positioned relative to thestator, corresponding to an early commutation and the actual commutation point isdetermined by a delay correction, determined by separate measurement for each motor(10), which is adjustable in the electronic commutation controller (30).
