An electric machine that includes a stator having a sheet metal packet which has an end plate at each end, and insulating plates abutting against the end plates. The packet has radially inwardly opening winding grooves. Insulating plates are provided at the ends of the packet and have recesses that correspond to the grooves and ribs that form abutment faces against which winding liners provided in the grooves abut. The ribs are shaped such that the windings emerging from the grooves will not cut through the liners when bent sharply. The ends of the groove liners are shaped by thermal stamping to lie against the side faces of the ribs.

The invention relates to a connecting device for the stator winding of an electric machine such as an electric motor. The winding head is contained within a cover unit. The connecting device is installed within the cover unit and is used for joining the winding ends of the winding head with external heads. The connecting device has a head portion with grooves for receiving the winding ends and leads and a plug-in foot portion which is insertable into the grooves of the stator lamination packet.

The invention relates to an electric machine such as a motor having a stator lamination packet with winding heads at opposite ends thereof. A cover for each or either winding head has inner fingers which extend into the grooves of the stator packet and outer fingers with wedge shaped portions which extend between the inner fingers in the installed position. The wedge shaped portions are resiliently mounted relative to the cover proper. The wedge shaped portions have one set of edges engageable with an end face of the stator packet and a second set of relatively inclined edges engageable with the underside of the associated winding head. Circumferentially arranged grooves in the wedge shaped portions hold a ring which biases the outer fingers radially inwardly to bunch the winding head into a predetermined confined space.
