AeroVantage ~ Motor / Engine

Notes: To eventually be moved.

• Motor:
• Proposed Features:
• An electric motor is located at each PropRotor.
• Optimally, the motor will be slow turning and thereby negate the need for gearing.
• Each motor will probably have 2 (or more) totally independent electrical power and control circuits; redundancy for safety.
• The coils, which are stationary, can be divided up among 2 or 3 independent power and control circuits, as mentioned above.
• The only moving parts on an Outrunner style motor will be the permanent magnets and their outer encasement, plus bearings and stub shaft.
• The motor is brushless.
• It should be possible to put the rotor's pitch control mechanism through the center of the motor; hollow shaft.
• Consider putting a Torque-Pitch coupling in each proprotor head. This will allow pilot and gyro instigated changes in electrical power to instantly adjust the rotor's collective pitch and thus a faster response. See http://www.unicopter.com/ElectrotorSimplex_Hub.html
