Abstract

The present application discloses a cooling system for a drive motor for an alternative fuel vehicle, the drive motor comprising a motor housing, a stator core arranged in the motor housing, and a stator winding arranged inside the stator core, wherein the stator core is formed by a lamination of a core punch, characterized in that the cooling system comprises: a flow guiding configuration for directing a coolant flow around an outer periphery of the stator core to cool the stator core, the flow guiding configuration comprising alternately arranged diversion regions and convergence regions; one or more coolant inlets for introducing the coolant from outside the cooling system; a flow guiding hood for directing the coolant flow to the ends of the stator windings to cool the ends of the stator windings; and a convergence port for allowing the coolant in the flow guiding configuration to pass so that the coolant flows from the outer periphery of the stator core to the flow guiding hood.
