摘要： An electric motor may include a stator assembly comprising a stator housing, and one or more rotors coupled to the stator by a rotor shaft assembly. The stator housing may include a cooling structure that has a plurality of cooling body portions and a plurality of cooling conduits defined by the plurality of cooling body portions. A method of forming a stator housing for an electric machine may include additively manufacturing a stator housing that includes a cooling structure defining a fluid domain, coupling a working fluid source to the stator housing and introducing a working fluid into the fluid domain defined by the cooling structure, and sealing the cooling structure with the working fluid contained within the fluid domain of the cooling structure. A method of cooling an electric machine may include heating the working fluid in the fluid domain and flowing the working fluid through the fluid domain, and transferring heat from the cooling structure to a cooling fluid flowing along one or more cooling surfaces contacting a surface of the electric machine.

摘要： An electric machine includes at least one rotor module. A rotor module includes a rotor hub having a hub body, and a plurality of first protrusions and a plurality of second protrusions. One or more first protrusions include an elongated portion and a head portion. One or more second protrusions include a wedge-shaped profile. The rotor module further includes a magnetic core having a plurality of core members disposed on the rotor hub. A core member of the plurality of core members is disposed such that the head portion of the first protrusion located between the adjacent second protrusions engages with the core member, and each of the one or more second protrusions extends at least partially in a space between adjacent core members of the plurality of core members. Moreover, the rotor module includes a permanent magnet disposed in a space between the adjacent core members.
