Abstract
The present invention comprises a rotor rotatable about a central axis, a stator having a stator core radially opposite the rotor across a gap, and a guide element arranged on a first side of the axial direction of the stator core and supplying a coolant circumferentially. Several stator flow paths are provided on the stator core, penetrating the stator core axially and carrying the coolant. These multiple stator flow paths are arranged at different positions circumferentially. The guide element has a connecting flow path section that links the multiple stator flow paths and is formed from several flow path elements stacked axially.
