Abstract
The invention relates to an electric machine, in particular to a generator for supplying the electrical system of a motor vehicle, comprising a laminated rotor () with an energiser winding (), which provides the energisation for the machine preferably in conjunction with permanent magnets () arranged on the rotor periphery. According to the invention, the rotor laminate bundle () is made up of at least two part bundles () in the axial direction with grooves () running into each other and with poles offset relative to each other (to). A machine with reduced detent torque is thus obtained with grooves () aligned parallel to the axis, in which the energiser windings () can be placed with a high filling factor and without production difficulties and without the risk of damaging the winding insulation.
