MAKE: ElectrotorPlus ~ MRGA - Motor - General

• High-speed, axial or radial flux, electric motor.
• Go with radial flux since this will result in a much smaller changes in air gap.
• If radial flux used place the rotor on the outside so that the moment arm is as long as possible.
• The stator is mounted to the fixed mast via a universal joint. The stator can piviot about the X-axis and Y-axii but it cannot rotate about the Z-axis.
• The gears will fling oil onto the back of the stator. This oil could be used to cool the stator as well as cool and lubricate the gears.
• Both motors will probably be about 15 hp each.
• The rotor of this electric motor is also the rotor of the gyro.

• Consider using the Fisher & Paykel motor; except increase the lamination count for more torque and use 300volt, etc. etc. For very high RPM.
