Vehicles equipped with an electric motor including an open central region configured to enable release and/or operation of a device from within the electric motor

A rotor assembly for a rotor-based aerial vehicle, the rotor assembly comprising:

• an electric motor including a stator, a rotor, and an open central region, the rotor configured to rotate relative to the stator, the open central region located radially inward relative to the stator;
• a plurality of rotor blades operatively coupled to the rotor, wherein each one of the plurality of rotor blades is pivotable relative to the rotor;
• a control shaft extending through the open central region, the control shaft configured to move along an axial direction relative to the rotor;
• and
• a plurality of control arms, wherein each one of the plurality of control arms is operatively coupled to the control shaft and further operatively coupled to a corresponding one of the plurality of rotor blades, wherein movement of the control shaft along the axial direction relative to the rotor causes a pivotal movement of each one of the plurality of rotor blades relative to the rotor.

A marine vessel, comprising:

• an electric motor including a stator, a rotor, and an open central region, the rotor configured to rotate relative to the stator, the rotor having an exterior surface, the open central region located radially inward relative to the stator;
• a plurality of propeller blades operatively coupled to the rotor, wherein each one of the plurality of propeller blades extends radially outward from the exterior surface of the rotor and also projects radially outward relative to a surrounding portion of an exterior surface of a longitudinal body of the marine vessel, wherein rotational movement of the rotor causes a corresponding rotational movement of the plurality of propeller blades, thereby causing the marine vessel to be propelled within an underwater environment;
• and
• a device or a component located at least partially within the open central region, wherein the device or the component is operable or usable from within the open central region while the rotor is rotating and the marine vessel is being propelled within the underwater environment.
