<p>Various methods and systems are provided for cooling an electric motor. In one example, a frame (106) for an electric motor (100) includes, an outer frame layer (108), an inner frame layer (110), and a liquid coolant passage (116) positioned between the inner frame layer (108) and the outer frame layer (110), wherein the inner frame layer includes a first opening (128) to allow air from an air passage (122) among a rotor of the electric motor (100) to flow between the inner frame layer (108) and the outer frame layer (110) and across the liquid coolant passage (116). Therefore, interior components of the electric motor may be cooled.</p> |
