Where the dimension L is 26,5 mm.

Encoder in the motor

A sensor based on the Hall effect detects 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- motorpower supply
  • Black -engine power
  • Green- encoder masspotential
  • Blue- Encoderpower supply(3.5 V - 20 V)
  • Yellow -encoderoutputA
  • White- encoder Boutput

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