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.

An electric motor is provided. The stator includes a core and a stator cage. The stator core is comprised of a plurality of axially stacked laminations. The stator cage includes a pair of end plates positioned adjacent the axial ends of the rotor core. The stator cage also includes at least one axially extending bar that interconnects the end plates. The stator core, the end plates, and the at least one bar are interconnected to form an integral body that is supported on the motor frame. The at least one bar presents opposite ends and includes a bore that projects axially from one of the ends. The bore is exposed to facilitate lifting of the stator.
