2.1 Technical description
The BELUGA represents a whole new generation of drive units for stone cutting. The exceptionally com-
prehensive modular system offers the flexibility needed today when performing cutting work in concrete
and stone. To achieve this, newly developed high-frequency motor parts are used in the motor. The fre-
quency range is controlled by the frequency converter from 0 - 1000 Hz integrated into the Powerbox. At
1000 Hz, the rotor reaches a speed of 30.000 min -1 . A major benefit lies in the exceptional weight / power
ratio (motor power output = 8 kW / weight = 6.5 kg -> 1.2). Using conventional technology e.g. type
BBM33extra (motor power output = 2.4 kW / weight = 13.5 kg -> 0.17) It means that the weight of the ma-
chine has been reduced sevenfold using the high frequency technology. We have succeeded in running the
Powerbox as well as the drive units on a 230V single phase network or on a 400 V three-phase network.
This means that only one piece of equipment is needed for use on both voltage sources. Further benefits
lie in the stepless speed control. This enables the best speed to be assigned to each tool diameter, in order
to attain the best possible cutting speed on the tool. During work, the speed can be steplessly reduced if
you come up against steel reinforcements and thus can be optimised according to the progress of the work.
Here, you can run the unit at much higher cutting speeds (Attention! depends on the tool) and in doing so,
the progress of the job can be speeded up by up to 150%. With conventional machines, the torque drops
very sharply at the higher speeds. Therefore, this advantage does not apply to conventional machines.
