Abstract: The present disclosure relates to a system for cooling a stator core of an electric motor. The motor cooling system according to the present disclosure is advantageous in that the number of parts can be minimized, and cooling efficiency can be maximized with a cooling fluid evenly distributed to a heat-generating area, by improving a typical design (a core press-fit stop end) of a housing supporting the stator core to add a fluid guide and a nozzle shape or by applying a nozzle ring formed in a curved shape and capable of spraying the cooling fluid after being received and stored to an end of the housing.
