Abstract: The invention relates generally to electrical propulsion of aircraft, and in particular, to electric motors that rotate propellers to produce thrust. A major challenge in electric propulsion is the thermal management of the electric motor, motor controller and battery. Conventional examples of electric aircraft place the electric motor within a cowling and connect a heat transfer system to said motor in order to move waste heat into the airstream outside of the aircraft. A streamlined electric aircraft motor and motor controller unit is disclosed, which places the waste heat generating components directly in convective thermal contact with the airstream outside of the aircraft. In order to facilitate the rapid transfer of waste heat from the motor/controller to the external airstream, the motor's electromagnets are located in a motor stator, which is external to the rotor, and thermally connected to the aerodynamically streamlined housing.

Abstract: The invention is an improved ratchet to drive sockets for the purpose of tightening or loosening threaded fastener. The invention contains an electric motor, battery and worm gear system to drive the sockets. The battery and motor are contained within the handle of the invention and are thus limited in size and power. A switch is also located on the handle and is used to activate the motor in the desired direction. The motor is powerful enough to drive most fasteners when the fasteners are somewhat loose, and as such the invention can drive the loose fasteners rapidly. At such times when the fasteners are snug or tight the invention will perform as a conventional ratchet. As the handle is pulled the worm and pion gears will lock and transmit the torque to the socket. As the handle is released the motor will drive the worm and spin the pion gear/socket and take up all of the slack.
