Abstract
An electric motor includes a rotor and a squirrel cage winding. The squirrel cage winding has two rings, which are axially spaced apart from each other and are interconnected by bars. The rotor has cutouts axially extending all the way through for receiving bars, and the cutouts are spaced apart from each other in the circumferential direction. The rotor has radially outwardly open axial grooves, and the radial distance range covered by the axial grooves contains the radial distance range covered by the bars.
