Blow moulder

Blow moulder

VLT® drives are available for permanent magnet motor operation for accurate positioning and synchronising control and fast ramp times. An algorithm in the VLT® AutomationDrive can manage almost all servo motors in closed-loop control with an external encoder attached to the motor. It communicates via ENDAT, Hyperface or Resolver encoders.
Reliability is critical
The internal speed controller provides stable and accurate circulation of the machine. Short downtimes are provided by a brake chopper that turns the motor into a generator to absorb the energy. In the production row the blow moulding machine is followed by the filler. If it is down, the filler is not served with bottles. Reliability of the blowing machine is critical for the entire production line. VLT® drives provide higher reliability of operation.
