Abstract
An electric motor includes a stator having a first side and a second side, a first housing coupled to the first side of the stator, and a second housing coupled to the second side of the stator. A shaft of the electric motor has a first end and a second end. The shaft is rotatably supported by a first bearing and a second bearing. A propeller of the electric motor couples to the first end of the shaft. An inverter includes an inverter housing directly coupled to the first housing.
