The system may further include a cowl comprising an air duct configured to direct heated air into the channel to deice the propeller blade. The cowl may be configured to selectively couple to the propeller and an electric motor and form a seal between the cowl and the electric motor to capture the heated air exuded by the electric motor. Additional systems and methods are also disclosed.

A vehicle includes a body, at least one propulsion system including an electric component, a strut extending between the body and the at least one propulsion system, and a cooling system operably coupled to the electric component of the at least one propulsion system. A portion of the cooling system is arranged within the strut.

The boom includes one or more inlet located on a first surface of the boom and within an airflow of said at least one propeller; at least one outlet on a second surface of the boom; a hallow channel extending in interior of the boom from said at least one inlet to said at least one outlet, wherein said airflow generated by said at least one propeller passes into said at least one inlet through the hollow channel to said at least one outlet providing cooling for said heat transfer device.

A rotor of a motor includes a cylindrical portion, a first plate portion, a second plate portion, and a side hole. The cylindrical portion is arranged on a radially outer side with respect to the stator and extends in the axial direction. The first plate portion is arranged on a first axial side with respect to the stator, and expands radially inward from a first axial end of the cylindrical portion. The second plate portion is arranged on a second axial side with respect to the stator, and expands radially inward from a second axial end of the cylindrical portion. The side hole penetrates the cylindrical portion in a radial direction. The stator holder has a holder through-hole. The holder through-hole is arranged on the radially inner side with respect to the stator and penetrates the stator holder in the axial direction.

Disclosed is an aerial vehicle. The aerial vehicle may include a removable battery. Various embodiments of removable battery assemblies include a pull-bar battery assembly, a latch battery assembly, and a lever battery assembly. The aerial vehicle may also include a propeller locking mechanism to which propellers may be removably coupled. The propeller locking mechanism may obviate the need for tools for coupling or decoupling propellers to the aerial vehicle. Vents in the arm of the aerial vehicle may provide an air pathway, providing convective cooling for the electronics aerial vehicle.

Propulsors (e.g., an electric motor mechanically coupled to a rotor) are described that passively cool the electric motors via an airflow path through the electric motor and out of the rotors. One embodiment comprises a method of cooling an electric motor. The method comprises operating the electric motor of a propulsor for an aircraft to rotate a rotor of the propulsor, where the rotor has one or more air outlets, and where the electric motor has a housing that includes one or more air inlets in fluid communication with the one or more air inlets. The method further comprises generating, by rotating the rotor using the electric motor, an airflow through the electric motor from the one or more air inlets to the one or more air outlets to cool the electric motor.

A motor controller of an unmanned aerial vehicle (UAV) is optimized to improve operation of the UAV. The motor control optimizations include controlling a motor of a UAV to reduce an operating temperature of the UAV, reducing an amount of latency or jitter resulting from motor operation, and applying a smoothing filter for motor operation. For example, controlling a motor of a UAV to reduce an operating temperature of the UAV can include using a temperature model for the unmanned aerial vehicle or an operating temperature measurement to determine a current operating temperature and comparing that current operating temperature to a threshold. If the threshold is exceeded, settings of the motor are adjusted to cause the motor to operate in a manner that reduces the current operating temperature.

A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.
