U211B2/ B3
The circuit is designed as a speed control on the
reflection-coupled principle with 4 periods per revolution
and a max. speed of 30.000 rpm. The separation of the
coupler from the rotating aperture should be 1 mm
approximately. In this experimental circuit, the power
supply for the coupler was provided externally because of
the relatively high current consumption.
Instructions for adjusting:
D
In the initial adjustment of the phase-control circuit,
R
2
should be adjusted so that when R
14
= 0 and R
31
are
in min. position, the motor just turns.
D
The speed can now be adjusted as desired by means of
R
31
between the limits determined by R
13
and R
14
.
D
The switch-off power of the limit load control can be
set by R
9
. The lower R
9
, the higher the switch-off
power.
