Abstract
A motor housing 20 for an axial flux motor 10. The motor housing 20 includes at least one housing portion 22, 24 which is of at least partially double-walled configuration, in order to configure an internal cooling channel 40 in the housing portion 22, 24. The cooling channel 40 extends in a substantially annular manner in the circumferential direction 6 between an inlet 41a and an outlet 41b, in order, during operation, to produce a first cooling flow 82 which flows substantially in the circumferential direction 6 through the cooling channel 40. Furthermore, the cooling channel 40 includes a plurality of transverse ribs 50.

A motor housing (20) for an axial flux motor (10) comprising:
- at least one housing portion (22, 24) which is of at least partially double-walled configuration, in order to configure an internal cooling channel (40) in the housing portion (22, 24),
- the cooling channel (40) extending in a substantially annular manner in the circumferential direction (6) between an inlet (41a) and an outlet (41b), in order, during operation, to produce a first cooling flow (82) which flows substantially in the circumferential direction (6) through the cooling channel (40), the cooling channel (40) comprising a plurality of transverse ribs (50), at least some transverse ribs (50) protruding into the cooling channel (40) in the axial direction (2) to a lesser extent in one of a radially inner rib portion (52) or a radially outer rib portion (54) than in the respective other rib portion (52, 54), in order to form an increased rib passage (72).
A motor housing (20) for an axial flux motor (10) comprising:
- at least one housing portion (22, 24) which is of at least partially double-walled configuration, in order to configure an internal cooling channel (40) in the housing portion (22, 24),
- the cooling channel (40) extending in a substantially annular manner in the circumferential direction (6) between an inlet (41a) and an outlet (41b), in order, during operation, to produce a first cooling flow (82) which flows substantially in the circumferential direction (6) through the cooling channel (40), the cooling channel (40) comprising a plurality of transverse ribs (50), a rib intermediate region (70) being configured between in each case two adjacent transverse ribs (50), and a flow guiding arrangement (60) being configured in at least one rib intermediate region (70).
A motor housing (20) for an axial flux motor (10) comprising:
- at least one housing portion (22, 24) which is of at least partially double-walled configuration, in order to configure an internal cooling channel (40) in the housing portion (22, 24),
- the cooling channel (40) extending in a substantially annular manner in the circumferential direction (6) between an inlet (41a) and an outlet (41b), in order, during operation, to produce a first cooling flow (82) which flows substantially in the circumferential direction (6) through the cooling channel (40), the cooling channel (40) comprising a plurality of transverse ribs (50),
- the housing portion (22, 24) comprising a first wall portion (22a, 24a) and a second wall portion (22b, 24b), the cooling channel (40) being formed between the first wall portion (22a, 24a) and the second wall portion (22b, 24b),
- comprising, furthermore, a central housing (21) for receiving a shaft (32), a rotor (34) and a stator (36) of the axial flux machine (10), the central housing (21) having an axial housing opening at a first axial end (20a), the housing portion (22) being configured as a housing cover (22a) and being arranged at the axial housing opening in order to close the latter, and the first wall portion (22a) of the housing portion (22) being configured as a housing cover (22a), and the second wall portion (22b) being configured as a cooling cover (22b) for closing the cooling channel (40).
