Electrotor-SloMo ~ Control - Electric - Sensor - Hall Effect

• To detect the position of the motor's Rotor.

• OTHER: Electrical - Control - Sensor - Position

• Bilateral:
• Timing of phase changes by Hall encoders.
• Have one Hall encoder in each motor. These two encoders will be on different circuits, For example on P1 and on S1. The output of the Hall sensors will go to AND chips. I.e. P1 - phase A will be And-ed with S1 - phase A, etc. The output from this AND gate will therefore be timed to the latter of the 2 incoming pulses. Since the controller will want to optimze the change between phases this means that it is optimized for the lagging rotor. Obviously, if this is correct, it will act as a means of synchronization of the two (actually 4) motor's rotors. Likely yes, maybe no, since the additional power will increase the torque and the induced drag ~ until the rotor speeds up.
• The electric yaw control might also be linked in with this circuitry. However it will require its own 12 smaller power transistors.
• Should the encoders be 'Incremental'. ????
• Coaxial (SloMoCo):
• Quadrature versus Hall Sensors: For good description see: Freescale Semiconductor ~ 3-Phase BLDC Motor Control with Quadrature Encoder using 56F800/E Have hard copy.
