Abstract

An electrical machine contains winding coils, in which the winding coils are able to be slid from the stator bore on to pole bodies provided on the stator of the machine and are retained on the pole bodies. The power/space ratio of the winding space available on the pole bodies is able to be increased by inserting at least one clamping part on the end faces of the pole bodies between the specific end face and the mounted winding coil. This clamping part is provided with at least two retention arms which extend in mutual opposition in the circumferential direction of the machine. The clamping part extends with the retention arms under the winding coil on the coil side facing the exposed end of the pole bodies.
