2.2.1 Detection of the pulsator pulley rotation with the rotary detector

Two magnet has mounted on the pulsator pulley, And rotary detector has mounted to the mechanism case.

When those magnet through under the coil (Rotary detector), Electromotive force has occured on the coil.

And the electromotive force has changed to pulse, Then the microprocessor detects periodic of the pulse.

Periodic of the pulse:

Short→ Rotation磁磁磁Fast

Long→ Rotation磁磁磁Slow
