ELECTRIC MOTOR AND ELECTRIC VEHICLES EQUIPPED WITH SAME

摘要

The present invention relates to an electric motor and an electric vehicle equipped with same. The electric motor according to the present invention, comprises: a stator equipped with a stator core and a stator coil wound around the stator core; a rotor disposed to enable rotation about the stator; a cooling unit for cooling the stator, disposed to contact with the stator and in the interior of which cooling fluid flows; and a groove formed on the outer surface of the stator core for insertion of the cooling unit. Accordingly, cooling performance can be enhanced by reducing the heat transfer path, and the manufacture and coupling of the cooling unit is facilitated.
