Abstract

Provided is an electric motor capable of cooling a stator without being increased in size with a small number of components and even with simple work. The electric motor includes ring-shaped sealing members (34) having flexibility and being arranged on an inner diameter side of a stator coil (22) so as to surround inner diameter portions of coil ends. Cooling oil flowing from an upper part of a housing into the housing flows downward through coil end oil paths (37, 38) formed by the sealing members (34), coil end covers (32, 33), and the coil ends.
