In embodiment, an electric motor may, for instance, incorporate coils of wire, which may be similar to or the same as any of the electrically conductive components in the entirety of this disclosure, which are driven by the magnetic force exerted by a first magnetic field on an electric current. The function of the motor may be to convert electrical energy into mechanical energy. In operation, a wire carrying current may create at least a first magnetic field with magnetic poles in a first orientation which interacts with a second magnetic field with magnetic poles oriented in the opposite direction of the first magnetic pole direction causing a force that may move a rotor in a direction. For example, and without limitation, first magnetic element  308  in motor  300  may include an active magnet. For instance, and without limitation, a second magnetic element may include a passive magnet, a magnet that reacts to a magnetic force generated by first magnetic element  308 . In an embodiment, a first magnet positioned around the rotor assembly, may generate magnetic fields to affect the position of the rotor relative to the stator  304 . A controller may have an ability to adjust electricity originating from a power supply and, thereby, the magnetic forces generated, to ensure stable rotation of the rotor, independent of the forces induced by the machinery process. 
     Motor  300  may include impeller  344 , coupled with the rotor shaft  336 . An impeller, as described herein, is a rotor used to increase or decrease the pressure and flow of a fluid, including at least air. Impeller  344  may function to provide cooling to motor  300 . Impeller  344  may include varying blade configurations, such as radial blades, non-radial blades, semi-circular blades, and airfoil blades. Impeller  344  may further include single and/or double-sided configurations. Impeller  344  is described in further detail below. Additionally, or alternatively, in a non-limiting illustrative example, rotor shaft  336  may be mechanically coupled to cooling vanes. Cooling vanes are used to lower the temperature of a high-velocity mechanical part, like the rotor in an electrical motor. Cooling vanes may employ a plurality of physical principles to cool mechanical parts. Cooling vanes may draw cool air like a fan if mechanically coupled to the rotor at an angle sufficient to create a pressure differential in order to draw cool air from outside the motor housing into the relatively hot inner motor and cool internal mechanical parts by convection. The cooling vanes may alternatively, or additionally cool other components disclosed herein with the impeller. Convection cooling in principle, is cooling of a portion of a body by moving a fluid over it, the tendency of heat energy to move from high to low energy areas, like a hot spinning rotor to cool moving air. Additionally, cooling vanes may act as thermodynamic fins. Heat energy may be conducted through the cooling vanes from the hot rotor shaft to the tips of the cooling vanes, thus dissipating heat in a high-speed rotating part. Cooling vanes may be consistent with those disclosed in U.S. Pat. Application No. 16/910,255 entitled “Integrated Electric Propulsion Assembly” and incorporated herein by reference in its entirety. 
     Now referring to  FIG.  4   , an exemplary embodiment of an electric aircraft  400  is illustrated. Electric aircraft  400  may include motor  300  may be mounted on a structural feature of an aircraft. Design of motor  300  may enable it to be installed external to the structural member (such as a boom, nacelle, or fuselage) for easy maintenance access and to minimize accessibility requirements for the structure. This may improve structural efficiency by requiring fewer large holes in the mounting area. This design may include two main holes in the top and bottom of the mounting area to access bearing cartridge. Further, a structural feature may include a component of electric aircraft  400 . For example, and without limitation structural feature may be any portion of a vehicle incorporating motor  300 , including any vehicle as described below. As a further non-limiting example, a structural feature may include without limitation a wing, a spar, an outrigger, a fuselage, or any portion thereof; persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of many possible features that may function as at least a structural feature. At least a structural feature may be constructed of any suitable material or combination of materials, including without limitation metal such as aluminum, titanium, steel, or the like, polymer materials or composites, fiberglass, carbon fiber, wood, or any other suitable material. As a non-limiting example, at least a structural feature may be constructed from additively manufactured polymer material with a carbon fiber exterior; aluminum parts or other elements may be enclosed for structural strength, or for purposes of supporting, for instance, vibration, torque, or shear stresses imposed by at least propulsor  312 . Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various materials, combinations of materials, and/or constructions techniques. 
     Still referring to  FIG.  4   , electric aircraft  400  may include a vertical takeoff and landing aircraft (eVTOL). As used herein, a vertical take-off and landing (eVTOL) aircraft is one that can hover, take off, and land vertically. An eVTOL, as used herein, is an electrically powered aircraft typically using an energy source, of a plurality of energy sources to power the aircraft. In order to optimize the power and energy necessary to propel the aircraft. eVTOL may be capable of rotor-based cruising flight, rotor-based takeoff, rotor-based landing, fixed-wing cruising flight, airplane-style takeoff, airplane-style landing, and/or any combination thereof. Rotor-based flight, as described herein, is where the aircraft generated lift and propulsion by way of one or more powered rotors coupled with an engine, such as a “quad copter,” multi-rotor helicopter, or other vehicle that maintains its lift primarily using downward thrusting propulsors. Fixed-wing flight, as described herein, is where the aircraft is capable of flight using wings and/or foils that generate life caused by the aircraft’s forward airspeed and the shape of the wings and/or foils, such as airplane-style flight. 
     With continued reference to  FIG.  4   , a number of aerodynamic forces may act upon the electric aircraft  400  during flight. Forces acting on electric aircraft  400  during flight may include, without limitation, thrust, the forward force produced by the rotating element of the electric aircraft  400  and acts parallel to the longitudinal axis. Another force acting upon electric aircraft  400  may be, without limitation, drag, which may be defined as a rearward retarding force which is caused by disruption of airflow by any protruding surface of the electric aircraft  400  such as, without limitation, the wing, rotor, and fuselage. Drag may oppose thrust and acts rearward parallel to the relative wind. A further force acting upon electric aircraft  400  may include, without limitation, weight, which may include a combined load of the electric aircraft  400  itself, crew, baggage, and/or fuel. Weight may pull electric aircraft  400  downward due to the force of gravity. An additional force acting on electric aircraft  400  may include, without limitation, lift, which may act to oppose the downward force of weight and may be produced by the dynamic effect of air acting on the airfoil and/or downward thrust from the propulsor  312  of the electric aircraft. Lift generated by the airfoil may depend on speed of airflow, density of air, total area of an airfoil and/or segment thereof, and/or an angle of attack between air and the airfoil. For example, and without limitation, electric aircraft  400  are designed to be as lightweight as possible. Reducing the weight of the aircraft and designing to reduce the number of components is essential to optimize the weight. To save energy, it may be useful to reduce weight of components of electric aircraft  400 , including without limitation propulsors and/or propulsion assemblies. In an embodiment, motor  300  may eliminate need for many external structural features that otherwise might be needed to join one component to another component. Motor  300  may also increase energy efficiency by enabling a lower physical propulsor profile, reducing drag and/or wind resistance. This may also increase durability by lessening the extent to which drag and/or wind resistance add to forces acting on electric aircraft  400  and/or propulsors. 
     Still referring to  FIG.  4   , electric aircraft  400  can include motor  300 . Motor  300  may include a stator which has a first magnetic generating element generating a first magnetic field. Motor  300  may also include propulsor  312  with an integrated rotor assembly of the motor assembly which may include includes a hub mounted to stator, at least a second magnetic element generating a second magnetic field. First magnetic field and second magnetic field vary with respect to time which generates a magnetic force between both causing the rotor assembly to rotate with respect to the stator.
