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.

Shaft-mounted slinger for electric motor

An electric motor assembly includes a stator, rotor, housing, rotatable shaft, and cooling fan. The stator and rotor are at least partly housed in the housing. The shaft is associated with the rotor to rotate about an axis. The cooling fan is fixed to and thereby rotates with the shaft to induce airflow within the housing. The cooling fan includes a wheel plate projecting radially relative to the shaft. The cooling fan further includes a plurality of radial blades that project axially from the wheel plate. The blades define a series of radial channels. The wheel plate defines an axial plate opening therethrough in alignment with a respective one of the channels.
