  • Electric motor and electric vehicle having the same
    Patent number: 8937414
    Abstract: Disclosed are an electric motor and an electric vehicle having the same. The electric motor includes a stator including a stator core and a stator coil wound around the stator core, a rotor disposed to be rotatable with respect to the stator, and a cooling unit configured to allow a cooling fluid to flow therein and disposed to be in contact with the stator to cool the stator, wherein an outer surface of the stator core includes grooves in which the cooling unit is inserted. Cooling performance can be enhanced by shortening a heat transmission path, and the cooling unit can be easily fabricated and coupled.
    Type: Grant
