5. Electronic motor control
Starting current limiting
The electronically controlled smooth start takes care
that the machine starts without jerk. In this manner,
the splashing of the liquid materials is prevented at the
same time when switching on the machine. As a result
of the machine’s reduced starting current, a 16A fuse is
sufficient.
No-load speed reduction
The electronic control reduces the no-load speed of the
machine witch results in reduced noise and wear of motor
and gear.
Speed pre-selection
With the speed control the speed can be
continuousty preselected:
The necessary speed is dependent on the type of material
to be mixed. lt is recommended that it be confirmed with
a practical trial.
Speed selectlon
Two rpm ranges can be preselected with the speed selecter
switch:
Speed 1: 150 min-I - 300 min-I
Speed 2: 300 min-I - 650 min-I
The necessary speed depends on the type of the material
mixed and it is recommended to verify it by a practical
test.
Constant Electronics
The constant electronics keeps the speed between no-load
and load nearly constant and ensures uniform mixing of
the materials
Electronic overload protection
In case that the machine is extremely overloaded, an
electronic overload protection protects the motor from
damage. In this case, the motor stops and restarts only
after the feeding pressure is reduced.
