| description | The present invention relates to an electric motor for an electric vehicle, comprising: a housing; a stator having a stator core and provided inside the housing; a rotor having a rotor core and rotatably installed around a rotational axis within the stator core; a plurality of end rings respectively mounted on both ends of the rotor core; and a cooling unit cooling heat of the rotor by using air circulation inside the housing. The cooling unit includes: a plurality of first cooling passages formed inside the rotor core therethrough; a plurality of second cooling passages formed through the inside of the housing; a plurality of connecting passages connected to the first and second cooling passages to form an air circulating passage inside the housing; and a plurality of blade fins formed to protrude on any one of the plurality of end rings and circulating the air when the rotor rotates. The heat of the rotor is cooled by using the circulation of the air. Thus, the heat generated from the rotor can be absorbed.
