Abstract
A motor is cooled with a coolant. The motor includes a rotor rotatable about an axis, a stator including a stator core and windings wound about the stator core, a housing enclosing at least a portion of the stator, and a resiliently deflectable spray ring extending circumferentially relative to the axis. The spray ring defines at least one orifice configured to direct coolant on the stator. The spray ring presents first and second arcuately spaced apart ends defining a gap therebetween.
