成果简介	NOVELTY - The motor has a rotor provided with a hollow shaft (102-1) that is provided with multiple orifices (O). A stator stack (106-1) is provided with multiple stator windings (106-2) arranged around the rotor. The stator windings define multiple winding heads (106-3) and an axial side of the stator stack. Multiple conduits are connected to the orifices. A predefined section is connected to an inner periphery, an outer periphery and a side faces of the winding heads. The conduits extend radially from the shaft and substantially parallel to the inner periphery, the outer periphery and the side faces of the winding heads. The conduits are provided with multiple holes to realize a flow of cooling fluid on the inner periphery and the outer periphery. . USE - Permanent magnet (PM) electric motor for use in a cooling system (claimed) of an electric vehicle (EV) i.e. a car. ADVANTAGE - The motor improves cooling performance of a stator winding during high-heating operating conditions, thus improving longevity, performance, reliability, efficiency and durability of a motor main body, and hence improving efficiency and range of a vehicle, significant capacity of a battery connected to the main body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a cooling system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a PM electric motor for use in a cooling system of an EV. 102-1Hollow shaft 106-1stator stack 106-2Multiple winding heads 106-3Multiple stator windings OMultiple orifices
