Abstract:
Hollow motor apparatuses and associated systems and methods for manufacturing the same are disclosed herein. In representative embodiment, a hollow motor apparatus includes a rotor assembly rotatable about a rotation axis, a stator assembly positioned adjacent to the rotor assembly and coaxially with the rotor assembly relative to the rotation axis, and a bearing assembly operably coupled to the rotor assembly. The rotor assembly has an inner portion around an opening configured to receive at least a portion of a payload. The bearing assembly is disposed outside the inner portion of the rotor assembly and is configured to maintain a position of the rotor assembly relative to the stator assembly.
