Abstract
An electric motor is disclosed. The electric motor includes a sheath for forming a main cavity, into which a coolant for cooling components of the electric motor is introduced. A stator is provided including a first stator end winding and a second stator end winding and a rotor. An impeller pumps coolant into a region of the first and second stator end windings. A dividing wall delimits a first coolant circulation chamber and/or a second coolant circulation chamber into zones that include an impeller inlet zone, an impeller air gap zone, an impeller outlet zone, an injection zone. The dividing wall is an independent component that includes a plurality of spacers for providing the zones.
