Feaam Gmbh | Date: 2015-04-21

The present invention provides an electric machine with a stator (1) and a rotor (21) mounted movable relative to the stator, wherein the stator comprises a plurality of slots (2) for receiving a stator winding. Exactly one conductor portion (3) of the stator winding is inserted into each slot. The conductor portions (3) are short-circuited with one another in a short-circuiting element on a first side (5) of the stator and are integrally formed with said short-circuiting element. On a second side (6) of the stator, the conductor portions (3) are connected to in each case one terminal of a power supply unit (8) which supplies adequate phase currents.
