2.0 General instructions
2.1 Technical description
The
BELUGA SXM
with the Powerbox
PB RX/SX12
represents a whole new generation of drive units
for stone cutting. The exceptionally comprehensive 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 frequency 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 machine 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.
2.2
Applications
The drive units and the related Powerboxes can be used according to the data attached to the information
plate. If you are using custom-built machines, the details on the quotation and the order confirmation also
apply.
The drive units and Powerboxes are essentially Class I appliances, this is only guaranteed by the full high-
quality protection of the residual current circuit breaker.
If suitable saw blades and drill bits are used, a wide range of materials can be cut:
- Concrete (even with strong reinforcement)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt road surfacing
The machine must
-
when operating at 230 V:
Be used with an upstream, all-current-sensitive residual current circuit breaker or safety
transformer in order to guarantee the safety of the operator.
- when operating at 400 V:
Be connected to a properly earthed CEE plug socket (CEE 5 pin, 3P+PE 32A 6h – 400V). The
neutral wire is not required.
Be used with an upstream, all-current-sensitive residual current circuit breaker or safety
transformer in order to guarantee the safety of the operator.
