Abstract
An induction motor for a chiller assembly is provided. The induction motor includes a housing and a stator having a cylindrical shape with a first end, a second end, an interior surface, and an exterior surface. The cylindrical shape defines a central axis. The induction motor further includes a rotor and a shaft with a first end and a second end. The rotor and the shaft are configured to rotate within the interior cylindrical surface of the stator about the central axis. The induction motor additionally includes a first bearing assembly located proximate the first end of the shaft, a second bearing assembly located proximate the second end of the shaft, a first nozzle ring and a second nozzle ring. The first and second nozzle rings are configured to direct a cooling fluid between the interior surface of the stator and the rotor.
