Abstract
Disclosed is a direct slot cooling system for motors, including a stator configured to expand an inner slot space of a stator core where a coil is wound to form a cooling slot through which a cooling fluid passes; a rotor coupled to a center of the stator to rotate; and a housing coupled to left and right sides of the stator to form a cooling jacket in watertight communication with a cooling slot so that a cooling fluid circulates in the cooling jacket.
