Abstract
An electric motor system for powering a propeller has a central shaft engageable to a mount on an aircraft around which an annular housing rotates. The annular housing is engaged with propeller blades using blade mounts connected to the annular housing directly or upon brackets. The brackets are removably engageable with the annular housing to provide for change or repair of propeller blades.
Claims18
An electric motor apparatus powering a propeller, comprising:
- an electric motor having a shaft forming an inner stationary stator and having an annular housing operatively engaged to and surrounding said shaft, said housing including a curved exterior circumferential surface rotating around said shaft upon communication of electric power to said electric motor;
- at least one bracket having an interior opening sized equal to a circumference of the curved exterior circumferential surface, the interior opening configured to removably mate with the curved exterior circumferential surface by sliding thereon;
- a plurality of blade mounts positioned on said at least one bracket;
- a plurality of propeller blades, each of said propeller blades having a first end engaged to a respective said blade mount;
- and
- said shaft having a first mounting hub located on at least one end thereof, said first mounting hub for connecting said shaft to a fixed position on a first mount on an aircraft.
