Abstract: A motor housing for enclosing a first stator module and a second stator module of a motor is provided. The motor housing includes a stator housing. The stator housing has a first module portion coupled to the first stator module, wherein the first module has a first contoured shape complimentary to the first stator module. A second module portion is coupled to the second stator module, wherein the second module has a second contoured shape complimentary to the second stator module. The housing also includes a base portion having a first side coupled to the first module portion and a second side coupled to the second module portion. The base portion further includes a third side coupled to and extends between the first side and the second side. A rotor housing is coupled to the stator housing and has a fastener coupled to the third side.

Abstract: In one aspect, an electric machine is provided. The electric machine includes a housing including at least one air intake, an air outlet, and an air passage extending between the at least one air intake and the air outlet. The electric machine also includes a first heat sink positioned at least partially within the air passage, and a second heat sink positioned at least partially within the air passage downstream of the first heat sink. A cooling airflow through the at least one air intake flows through the air passage to cool the first heat sink and the second heat sink before the cooling airflow is exhausted through the air outlet.

Abstract: In one aspect, a three-phase axial flux stator is provided. The stator includes a plurality of stator modules oriented in an axial direction, and each of the stator modules includes a pair of teeth connected by a yoke section. The stator also includes a plurality of windings, each of the windings wound around one of the stator modules. The stator modules and the windings produce a three-phase flux in an axial direction.
