Abstract
A coolant flow enhancing device is provided to increase electric machine coil cooling at coil end turn locations. Such a device is incorporated into an overall fluid cooled electric machine that has phase separators extending through slots between stator teeth. The device includes flow deflectors located at ends of the phase separators. Each of the flow deflectors is designed so that a contour of its interior surface follows an outer contour of a corresponding one of the end turns to both maximize a cooling fluid flow rate past the one of the end turns and minimize separation of the fluid from the one of the end turns.
