Abstract:
A slinger for an electric motor broadly includes a hub and a wheel. The motor includes a housing in which a stator and rotor are at least partly housed. The motor also includes a rotatable output shaft projecting upwardly through a shaft opening in the housing. The hub is fixedly attachable to the output shaft of the motor so that the slinger rotates with the output shaft. The wheel is configured to divert liquid radially away from the shaft opening. The wheel includes a wheel plate and a plurality of radially extending blades cooperatively forming a series of passages extending radially outward relative to the shaft opening, when the hub is attached to the output shaft. The wheel plate is supported by the hub so as to be positioned above the housing when the hub is attached to the output shaft. The blades present radially inboard ends intersecting the hub.
