Abstract
A synchronous reluctance machine includes a rotor having a plurality of rotor disks with longitudinal flux barriers. When the rotor disks are stacked together to form a rotor core, the flux barriers define channels extending in an axial direction of the rotor core. Air is forced to flow through these channels in order to improve a temperature distribution within the machine.
