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
