Encoders - feedback

Hall effect sensors detect pulses on a rotating magnetic disk at the back of the engine. Square encoders allow measurement with a resolution of 64 pulses per motor shaft revolution. After the gearbox, this is the right number of times more.

The outputs:

  • Red- motor power supply
  • Black -engine power
  • Green- encoder mass potential
  • Blue- Encoder power supply (3.5 V - 20 V)
  • Yellow -encoder A output
  • White- encoder B output

The figure shows the signal from both encoder channels. The B signal is shifted in phase relative to the A signal by 90 degrees.
