Abstract:
The present invention provides an axial flux motor (10) having: a rotor (20) having a radially extending portion (20r) and an axially extending portion (20c) having a first side (20a) and a second side (20b); a stator (22) having an inner aperture (30), a front wall (34) having a first side (34s) and a second side (34i) and being axially spaced from the first side (20a) of the rotor (20) by a gap (38), a bearing member (32) within the inner aperture (30) of the stator (22) and supporting the axially extending portion (20c) of the rotor (20); a casing (40) having an axially and circumferentially extending outer portion (48) surrounding said rotor (20) and having an inner surface (43); a cover plate (42) having an inner face (42i) confronting and being spaced from said second side (20b) of said rotor (20); a containment chamber (26) including said second side (34i), and said inner face (42i) of said cover plate (42) and having a top portion (45); a sump (50) within the containment chamber (26); and one or more first flow diverters (60) on the inner surface (43) of casing (40) to direct liquid towards said first and/or second inner side faces (34i, 42i).
