Abstract
A stator for an electric machine includes a stator carrier having a plurality of grooves with a respective groove base, and a motor winding having at least one first strand. A predetermined number of first grooves of the plurality of grooves is associated with the first strand. At least one coil section of the first strand is introduced into each of the first grooves. The first strand has a plurality of individual wires connected electrically in parallel, with each wire formed as a round wire. At least some of the individual wires in each of the coil sections are arranged above one another in a radial direction of the stator. The coil sections are each arranged in the first grooves in such a way that an average radial distance of the individual wires to the groove base is equal for all individual wires.
